<h3>Energy transfer in the ecosystem</h3>
Energy is transferred from lower to higher trophic levels of the food chain in any ecosystem.
In other words, energy is transferred when primary consumers feed on producers, when secondary consumers feed on primary consumers, and so on.
However, when energy is transferred through feeding from lower to higher trophic levels, a certain percentage of the energy is lost to the surroundings as heat.
In actual fact, scientists believe that about 90% (and not 30%) of the energy is lost as heat to the surrounding. Only about 10% of the energy is converted to useful energy.

Jenna and Allen are both correct. Homeostasis refers to certain processes that take place to keep the body in normal or stable state. Maintaining the body temperature at normal measurement is an example of homeostasis, as well as increasing breathing rate when exercising. Breathing and heart rate is increased to deliver oxygen and glucose to the body more quickly and remove carbon dioxide wastes.
