Q: Biomass???
I have to write a report on biomass and one of the things I have to find is Political connections. I guess that means does the government want people to use it or not or if most people like it and why. I can’t find any good political connections. Can you please give me a few links a some good sites? Thanks! <3

A: Biomass is a renewable energy source, unlike coal/gas/oil etc. so is less harmful to the environment and will not run out. As global warming and energy conservation are major international political issues at the moment, many politicians and members of the public support biomass fuels. However, the reality is that biomass use is currently infeasible and under-developed. Therefore, solar power/wind power/nuclear power are all more popular.

Q: How can I measure the biomass of a plant in a certain area without pulling up plants?
I am doing an experiment to see if the biomass of Marram grass changes as you move over sand dunes (does exposure affect biomass) but need a way to measure biomass without pulling up plants, drying them and weighing them all, as this is illegal! Any ideas?

A: Perhaps you can isolate a certain area and measure the CO2 consumption during photosynthesis. This can be related the biomass.

Q: How does biomass of an organism change as the depth of ocean increases?
Advanced Higher Biology.

How does the biomass of an organism change as the depth of the ocean changes? And what are the factors that affect the rate of photosynthesis and chemosynthesis for the increase in biomass?

Thanks so much in advance!

A: If you mean any organsim, then its biomass should not change with increasing depth. e.g. if we plunge you into the deepest ocean trench, assuming you live, the increased pressure will squish you but will not affect your fundamental composition.

If you mean the biomass in the ecosystem, seafloor, chemoautotroph-based ecosystems will start with a bit less biomass overall as they aren’t tragically efficient and there’s not a great deal of diversity in those food webs.

Factors that affect the rate of photosynthesis and chemosynthesis are the same as those that affect all enzyme-mediated reactions; heat, temperature, substrate Kc and enzyme Kc. Photosynthesis also depends on light intensity (which is kind of like a substrate to the light-dependent reactions if you think about it). Chemosynthesis has unique limits of the limiting factors; not being nearly as sensitive to “reasonable” temperatures.

Hope that helps!

Q: How would you explain biomass to a teacher in a powerpoint?
I have project in less than 2 weeks how can i explain biomass in a power point and what should i talk about ?how do i do it?im going crazy.

A: talk about:
1)cost
2)availability
3)national safety
4)environmental concerns
5)conservation
i don’t know that much about biomass but it includes wood and waste, which produces about 1.3 pounds of CO2 for every kilowatt produced.
good luck!

Q: What happens to the biomass of organisms as the level increases?
I have already looked over my textbook and study guide but i can’t seem to find it the information. I can only find what biomass means.

A: Biomass decreases are you go up on a food chain. Thats because the amount of available energy that is transferred to an organism after it consumes another decreases as you go up on a food chain. The bottom of the chain is plants and other autotrophs that make their own food directly then as they are consumed by heterotrophs like herbivores and carnivores the amount of energy transfer is only 5-10% thus it can only support a smaller amount of organisms (biomass)

Q: How much energy and biomass pass from one trophic level to the next?
How much energy and biomass pass from one trophic level to the next? Where does the rest go? What does this mean for farming methods where food is scarce?

A: It is actually only 10% I’m more than pretty sure that Ellie R is wrong, and I have this 20 page website to back me up. Basically here is everything YOU need to know:
“Only a fraction of the energy available at one trophic level is transferred to the next trophic level. The rule of thumb is 10%, but this is very approximate.” (but undoubtedly the number that your professor will want)
“Typically the numbers and biomass of organisms decrease as one ascends the food chain.
…
Assimilation = (Ingestion – Excretion)…
The hare uses a significant fraction of the assimilated energy just being a hare — maintaining a high, constant body temperature, synthesizing proteins, and hopping about. This energy used (lost) is attributed to cellular respiration.”(that is how you answer the second part)

“These efficiencies vary among organisms, largely due to widely differing metabolic requirements. For instance, on average vertebrates use about 98% of assimilated energy for metabolism, leaving only 2% for growth and reproduction. On average, invertebrates use only ~80% of assimilated energy for metabolism, and thus exhibit greater net production efficiency (~20%) than do vertebrates. Plants have the greatest net production efficiencies, which range from 30-85%. ” (cited source)

For the last part of the question I would assume that the answer is “when food is scarce there should be much less focus on providing the human population with meat because of the way energy is transfered. Even though more energy is gained from eating meat, there will be a loss due to cellular respiration. Farming animals is, therefore, less effective than eating the crop as is.” (me)

Q: Whats the difference between Waste to Energy and Biomass Energy?
I have to write a 15 page research paper on an alternative energy source that can be produced in a power plant. My teacher gave me some topics and i had chosen to do it on waste. I have been researching municipal solid waste incineration. I talked to a friend and she said she was also doing waste and she kept mentioning biomass. I thought that those were two completely different subjects. So now im confused if i should mention biomass in my paper or not. Please help me.

A: Waste to energy is basically burning your trash to create energy and biomass is burning anything that was once living or part of a living thing, like in places where they burn cow “pies” to cook their food that’s biomass.

Q: How does a biomass power plant get fuel year round?
Please provide sources. Please provide any sites about biomass power. How does a biomass power plant get the fuel it needs year round if it needs plant matter, and farms only harvest once, maybe twice, a year?

A: We burn tree bark in a biomass boiler. Trees are harvested year around by a paper mill. The bark is removed by a debarking drum and a conveyor takes the bark to a bark dryer, then to a surge bin where it is stored and fed by screw conveyors into the boiler. In addition waste paper and cardboard are run through a pelletizer. The waste paper(and cardboard) is shredded, compressed and extruded through dies where it comes out looking a little bigger around than a cigar. These cigar pieces are burned. We run it year around.

Q: What are two advantages and disadvantages of biomass energy?
Biomass energy is the use of biological matter known as trees, grass, and undeveloped remains to create a fuel that produces heat and electricty.

A: adv. Renewable, Domestically available
Disadvantage. Requires use of natural resources, releases CO2 and other poluttants.

Q: What is the impact of Biomass on the Environment?
I need both the pros and cons of biomass. Any extra information you can give me on biomass in general will be appreciated too.

A: Geothermal
Hydro power
Solar power
Tidal power
Wave power
Wind power

The above list mostly comprises of Biomass. It’s good for our planet because those energy are renewable. Less damage to the planet. So we benefit from it ;)

Q: What is the average leaf size and biomass of a grown Nasturtium?
If you know, what is the average leaf size and biomass of nasturtiums grown in acidic soil?

A: http://en.wikipedia.org/wiki/Nasturtium

Q: what is biomass and what is the process to make it into energy?
hye people.
can you intelligent people out there help me with this question.
what is biomass? and what is the process to turn biomass into energy as the alternative energy?
i google it but i got confused all over.
because, there is also a word biofuel, bioethanol.
oh please and please help me people.

A: Biomass is just a term meaning biological sources (read plants, animals, etc.).

Using biomass for fuel come in many forms -
1. eating food gives you physical energy;
2. burning wood provide heat energy;
3. making ethanol (fuel for cars) from corn provides fuel energy (bio-ethanol);
4. making bio-diesel fuel (fuel for trucks – different engine type) from used oil (like frying oil and even motor oil).

Technically, buring coal and oil is considered using biomass for fuel, as they are organically derived, but the current concept is meant to imply the use of organic sources that can be processed in much shorter timeframes (fossil fuels take millions of years to convert dead organic matter).

As for non-biomass derived energy? Examples are nuclear, wind and solar.

Hope this helps clear it up.

Q: How are glucose and biomass use to make decoration?
What is glocose and Biomass?
How they be useful to make decorations?

A: Glucose is a basic sugar, Lactose (in milk) breaks down into galactose 7 glucose.

Biomass is the environmental term desribing the weight of all living things in a given area. A peice of “biomass” would be a bit of anything organic, ie not a mineral. (though this is somewhat of a misusage of the term)

If you want to make a decoration, I guess you could use the sticky glucose to glue flowers(biomass) to the things you wish to decorate

Q: What would happen to plant biomass if the levels of carbon dioxide went up?
Would the plants biomass get bigger, because they have more carbon dioxide for photosynthesis, or would it decrease?
Thanks

A: They would increse due to a greater rate of photosynthesis.

Q: Ecosystems: How can a small biomass of producers support a larger biomass of consumers?
Hello..

How can a small biomass of producers (algae) support a larger biomass of consumers (zooplankton)?

And another question; How can you calculate the energy transfer between trophic levels? Is there a formula?

Thank you!

A: Doubt it, but the only way that would be possible would be if the producers grew as quickly as they were eaten by the consumers. In your example, the phytoplankton would have to reproduce faster than they were eaten by the zooplankton.

I rather doubt that’s the case. I’d bet on there being more phytoplankton biomass than zooplankton at all times.
