In the pyramid below, give an example of an autotroph and an example of a heterotroph
Answers
Answer:
In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy.
The energy in each trophic level of an energy pyramid is just 10 percent of the energy in the level below it. What accounts for the decrease in energy from the lowest level to the highest level of an energy pyramid?
All living things use some of the energy they get from nutrients to carry out life processes such as respiration and movement. In addition, some of this energy is lost as heat. As a result, the energy in ecosystems decreases from the lowest level to the highest level. This is also the reason why the number of levels in an energy pyramid is limited.
