Detailed explanation-1: -Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals. Dung beetles eat animal feces.
Detailed explanation-2: -When a rabbit eats a plant, nutrients from the plant become available to the tissues of the rabbit. During this process, some of the energy from these nutrients is lost. It becomes heat and unavailable chemical energy.
Detailed explanation-3: -The largest amount of available food energy is found on the first trophic level, the base of the pyramid. Less than 10% of the amount of food energy that is available in one level is available to the animals in the trophic level just above. That means each higher level can support fewer and fewer organisms.
Detailed explanation-4: -On a trophic pyramid, we place the decomposers in a special place along the side of the pyramid (as seen in your homework and notes) because they are responsible for breaking down the dead organisms at all trophic levels into small molecules called nutrients.
