Consumers do not use 100% for growth as some of the energy they use is used to maintain body temperature but also to contract muscles. As energy cannot be created or destroyed but only transferred the amount of energy as you go up the chain must decrease, so the primary producer must have the most biomass.

∙ 7y agoAn ecosystem is similar to a pyramid. The base must be very large to support the upper levels. There are always many more in the first level than in the second. More in the second than in the third. More in the third than in the fourth. That is because the upper levels can only support a certain number.

Why is the number of trophic level that can exist limited?
All sources of energy come from the sun. Autotrophs make their own energy through photosynthesis by collecting energy from the sun. When an organism (herbivore) at the next trophic level eats them they only get approximately 10% of the energy that the first organism had. When another organism eats the animal that ate the plate they only get approximately 10% of the energy of what that animal got from the previous animal. So this animal only got 1% of the energy from the sun. If more trophic levels existed they would only get 10% of this 1% so would not get enough energy (approximately 0.1%) so is why trophic levels are limited.
Why isn't alcohol production from biomass energy efficient?
distillation. Boiling the solution requires more energy than the energy content of the ethanol present.
Why is biomass a better alternative to oil?
Biomass is a renewable resource.
How is biomass renewed?
Biomass is renewable only if the vegetation it is burning is renewable!Biomass fuel is really any kind of vegetation that is burnt to produce electricity. Ideally this is residue from other crops, like the remains of sugar cane (bagasse) after they crush out the sugar juice. All these crops can grow quickly, in one season, so they are renewable. We can always grow more.Since biomass can be renewed in a shorter amount of time, and it doesn't get used up faster than it can be renewed, it is called "renewable".Biomass is used to make biofuels:EthanolBiodieselBiomass is a renewable energy source because it is used over and over again.Biomass is renewable because plants turn inorganic things into biomass and when we burn it, it turns back to inorganic things, which can then be turned into biomass again.Because vegetation can be burnt and then grow again. renewable!because it is waste and people and animals are inexhaustibleBecause they can grow crops and wood if they are replanted.Biomass is renewable because the sources used are regenerative. It is made of such things as living and recently living organisms like plants, forest residue such as fallen trees, yard clippings, garbage, and other organic materials. The materials are all ones that will not run out, making them renewable.Biomass is considered a renewable energy source because we can always make more of it. Biomass comes from trees and waste, which can easily be grown or created.Biomass Energy is considered renewable due to the fact that we can regrow it in a small amount of time. Take wood for example, it is considered biomass because it was once a living organism. It takes from 30 to hundreds of years for trees to grow fully. While that may seem like a long time, compare it to what we use now, fossil fuels. The length of the process for creating oil can take up to hundreds of thousands of years. In my opinion, I would rather wait fifty or so years, rather than a few hundred thousand.Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist.
What difference between A level and CBSE?
A level has been originated from Geneva and CBSE is an Indian course. A level is more than a hundred years old and is for people who has decided a specific route and have a determined mind. It would be a better option to choose A level but for keeping more options open CBSE would be more beneficial.
What does a biomass pyramid present?
Biomass - the total dry weight of the organisms in a trophic levelBiomass Pyramid - a diagram showing the biomass at each trophic level of a food chainA pyramid of biomass shows energy lost in each trophic level while a pyramid of numbers shows the numbers of the organisms in each trophic level
Why are there fewer organisms in the higher trophic levels than the lower trophic levels?
the temperature is higher and in generally the conditions of life is much easier... There are also many atmospheric and oceanic phenomena participating in making the environment much more friendly than any other geographic level. and of course, cause they're near me :)
What trophic level contains the greatest biomass in most ecosystems?
More individuals, less energy, more producers, or fewer carnivores?ANSWER: more individuals because there are more types of omnivores and carnivores(who feed off of primary consumers) than there are herbivores (who feed off of primary producers)
What is a biomass piramid?
An ecological pyramid of biomass shows the relationship between biomass and trophic level by quantifying the amount of biomass present at each trophic level of an ecological community at a particular moment in time. It is a graphical representation of biomass(total amount of living or organic matter in an ecosystem) present in unit area in different tropic levels. Typical units for a biomass pyramid could be grams per meter2, or calories per meter2.The pyramid of biomass may be 'inverted'. For example, in a pond ecosystem, the standing crop of phytoplankton, the major producers, at any given point will be lower than the mass of the heterotrophs, such as fish and insects. This is explained as the phytoplankton reproduce very quickly, but have much shorter individual lives.One problem with biomass pyramids is that they can make a trophic level look like it contains more energy than it actually does. For example, all birds have beaks and skeletons, which despite taking up mass are not eaten by the next trophic level. In a pyramid of biomass the skeletons and beaks would still be quantified even though they do not contribute to the overall flow of energy.(This is copied from Wikipedia)
Why does biomass decrease?
Biomass is defined as any biological material from living or recently living organisms. Since every living organism is a part of the food chain, less energy becomes available the more it climbs up the chain, resulting in a decrease in biomass.
How does the amount of biomass at the fourth trophic level compare to the amount of biomass at the third trophic level immediately below it?
Biomass at the fourth trophic level is approximately ten times smaller than biomass at the third trophic level.
What trophic level must have more of than others?
:) The 1st trophic level has more energy. The first trophic level consists of producers(plants and algae). They has more energy because they create their own food (photosynthesis). Hope this answer helps :)
What is an example of an animal that fill more that one trophic level?
Any omnivore is in more than one trophic level, such as a chicken that eats both heterotrophs (worms) and autotrophs (grain)
How trees can be producers and yet the smallest tropic level in a pyramid of numbers?
Trees are very large compared to the organisms they support, such as insects, birds and rodents. A single tree has much more biomass than the consumers depending upon it, meaning it is still the base of biomass pyramids and pyramids of energy. Therefore even if they are fewer in number trees still occupy the producer level of the trophic pyramid
Can an organism fill more the one trophic level?
Yes, when their diet varies they can fill more than one trophic level
What organism belongs to more than one trophic level?
mushroom
Can a single species feed at only one trophic level?
No, some species can feed at more than one trophic levels. For instance, humans can eat plants(first level), chickens(second level), and dogs(third level).
