What does the producer layer always have in the energy pyramid?
food
Why are there usually fewer organisms at the top of an energy pyramid?
The energy pyramid has a broad base to support the next level of organisms, then gets narrower as each layer is added. Each upper level eats more than one ie many organism from the layer below it. Therefore, there has to be more organisms and more energy trapped in lower layers to give energy to the upper layer. There is more grass than rabbits, there are more rabbits than hawks. There is more energy in the grass layer than the layers above it.
Why is there less energy at the top of the energy pyramid?
Energy decreases because only 10% of the energy stored at each trophic level is available to the next trophic level.
What always happens when energy is transformed?
Usually some energy is wasted, in the sense that it gets converted to a less valuable form of energy. In other words, entropy increases.
Where does the energy go that is lost in the energy pyramid?
Only the energy stored as biomass (stuff that the next organism up eats and successfully absorbs) makes it up to the next layer of the pyramid. The rest i lost because the animal doing the eating doesn't absorb all of the energy in the food, the animal moves around expending energy, some (quite a lot actually) is lost as heat in warm-blooded animals, etc. In fact very little of the energy absorbed by one layer of the pyramid through eating makes it up to the next layer.
What does the producer layer always have in the energy pyramid?
food
Which part on the energy pyramid has the highest amount of energy?
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.
What is the bottom layer of a pyramid that represents ecosystem producers and its top layers represent consumers called?
The bottom layer of pyramid that represents ecosystem producers is the ecological pyramids. The top layers represent consumers. In the energy pyramid the bottom levels have more energy than the top levels.

There is more energy in the grass layer than the layers above it.
How is matter and energy used in ecosystems?
Energy is described by a pyramid diagram (the ecological pyramid). There are 4 layers in the pyramid. The bottom layer is producers. They produce all the energy that goes up the pyramid. The second layer is the primary consumers, or herbivores, who eat the producers. Next, there is the secondary consumer layer, the organisms in it eat other consumers. Finally, there are tertiary consumers eat secondary and primary consumers.Note: as you go up the pyramid, the original energy from the level below it is reduced to 10% of the original energy from the level below it. The primary consumers get 10% of the energy the producers made, and so on, so the secondary consumers get 1% of the original energy, and the tertiary get 0.1% if the energy!See: http://en.wikipedia.org/wiki/Ecological_pyramid for a picture of the ecological pyramid.
What does the bottom layer of an energy pyramid represents?
It represents what gives it energy and what it gives energy to
What are pyramid of numbers and pyramids of biomass?
Pyramids of numbers show the amount of organisms in the chain, and pyramids of biomass show the biomass (mass of living things) of each organism in the chain. It is all shown in a pyramid shape. Definition of Pyramid of numbers: A pyramid of numbers shows graphically the population of each level in a food chain. Definition of Pyramid of Biomass: Pyramid of Biomass represents the total biomass at each trophic level. A pyramid of numbers shows the population size of each species in a food chain. A pyramid of biomass shows how much ENERGY each animal is getting from its food.
Why is there less energy at the top of the energy pyramid?
Energy decreases because only 10% of the energy stored at each trophic level is available to the next trophic level.
Which country is the leading producer of chloroflourocarbons?
United States is the lead producer of CFC's. These deplete the ozone layer.
The fatty layer of skin that stores energy?
The Subcutaneous Layer
The people on the bottom layer of the social pyramid?
the lower class
What do you call your legislative branch?
Another layer of a pyramid scheme
