it decreases.
square pyramid (bottom is a square)-5 points triangular pyramid (bottom is a triangle)-4 points
A square based pyramid.
A pyramid is a structure with a square at the bottom and 4 triangles connecting them. You have the correct word.
yes
Yes, it is a pyramid and a circle on the bottom
The Producers. Tends to be the bottom of the pyramid if you are studying a 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.
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.
A pyramid is bigger at the bottom and small and pointy at the top. so its bigger at the bottom, otherwise it would have been called an energy upside-down pyramid =). But anyway, energy enters a food chain from the sun. some energy and biomass is lost at each stage of a food chain as feaces, movement energy and heat energy (especiall birds and mammals). therefore only a small amount of energy and biomass is incorporated into a consumer's body and transferred to the next feeding level. the loss of energy and biomass at each stage is a representation of why the pyramid gets smaller at the top.
THE LEVEL ON the pyramid that has the most biomass is the tertiary level.
At the bottom. The amount of energy being passed on decreases as the pyramid goes up. For example, if the pyramid had 5 flowers on the bottom, 3 rabbits in the middle, and a hawk on top, the most energy would be with the flowers, and least passed on to the hawk.
it contains the least amount of the total energy.
Because the loss in biomass is so great a percentage from one level to the next, the top bar is just a vertical line to show that it is there but a tiny portion of what the bottom bar started.
it contains the least amount of the total energy.
it contains the least amount of the total energy.
The amount of energy in one section of the pyramid would always be less than the amount of energy in the section below it.
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
