What is the total dry weight of organisms in each level of a food chain or biomass pyramid?

Say, for example, you have a basic food pyramid consisting of two levels. A tree and caterpillars. The dry mass of the caterpillars mentioned on the level, which could be any amount of caterpillars, is the weight of the caterpillars minus any water. It's the same for all of the levels, but the number tends to be greater on the lower levels.
The only two ways to work this out is to "Dry out" the organisms, which would kill them, or by estimating it using an average dry mass for the organism mentioned.

What does a biomass pyramid measure?
Biomass. Pyramids of biomass and number are scientific models to represent all the things eaten in a foodchain. Pyramids of number are flawed as a great many insects may feed on a tree, for example, producing a narrow base to the pyramid. Pyramids of biomass are a better model as they show the dry mass of each part of the food chain and give a better indication of the energy passed between trophic layers. Biomass pyramids show the abundance of organisms at each trophic level.
How would a chart showing the concentration of toxins differ from a biological pyramid of biomass for the same food chain?
i believe the concentration becomes greater as you move up the food chain, or up the biomass pyramid, meaning that the highest level of consumer has the highest amount of toxicity. I always thought it was the other way around but I've done some research and that's what I found.
Why are producers important for the transfer of energy within an ecosystem?
Producers are the beginning of the chain of energy that travels through the food chain. These are organisms, such as plants, that turn inorganic material into biomass.
Which group of organisms has the least biomass?
A tropic level is the position that an organism occupies in the food chain. The trophic level that has the least biomass is trophic level 5, which is composed of apex predators.
What are the three ecological pyramids of environmental studies. Explain their types?
Energy Pyramids show how much energy is present at each level. It is a diagram that shows the relative amounts of energy within each trophic level in a food chain or web. Biomass Pyramids represents the amount of biomass within each trophic level. Numbers Pyramids show how many organisms there are at each tropic level. Energy pyramids are probably the most useful of the three!
What are the concept of an ecological pyramid?
The ecological pyramid is basically the food chain. So, the producers (plants) are at the bottom, then herbivores (plant eaters), then above them are the omnivores or carnivores, and then the most powerful and top of the food chain animals are at the top of the pyramid.
What does a biomass pyramid represent?
A pyramid of biomass shows how much energy the organism on a food chain is getting from its food.
What does a biomass show?
The biomass pyramid is a chart that is drawn to scale. It displays the biomass at each stage in the food chain.
What organism has the greatest biomass in the food chain?
The Producers. Tends to be the bottom of the pyramid if you are studying a pyramid.
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
What does a biomas pyramid represent?
I think you might be talking about a biomass pyramid. I never heard of a biotic pyramid. Take a look at this website. It might help you. http://earth.rice.edu/MTPE/bio/biosphere/topics/energy/40_biomass.html
What is the total mass of all organisms in a food chain?
biomass

In a food chain which organisms have the smallest numbers and smallest total biomass?
Those at the top of the food chain.
What is a enery pyramid?
If the organisms in a food chain are arranged according to trophic levels, they form a pyramid, with a broad base representing the primary producers and usually only a few individuals in the highest part of the pyramid. Also known as a "pyramid of numbers," an ecological pyramid is a way of describing the distribution of energy, biomass, or individuals among the different levels of ecosystem structure.
What happens to the biomass as you move up the food chain?
Biomass accumulates Think of it as a pyramid If the animals at the bottom consume a little then the next step up will have a little more in them because they just absorbed all of it when you get to the top you will have the highest concentration in the entire food chain.
The pyramid which best explains why there are typically only four to five links in a food chain is the pyramid of 1. energy. 2. productivity.3. biomass.4. matter. 5. number?
Energy
