<Li> Solar energy is fixed by the photoautotrophs , called primary producers , like green plants . Primary consumers absorb most of the stored energy in the plant through digestion , and transform it into the form of energy they need , such as adenosine triphosphate ( ATP ) , through respiration . A part of the energy received by primary consumers , herbivores , is converted to body heat ( an effect of respiration ) , which is radiated away and lost from the system . The loss of energy through body heat is far greater in warm - blooded animals , which must eat much more frequently than those that are cold - blooded . Energy loss also occurs in the expulsion of undigested food ( egesta ) by excretion or regurgitation . </Li>
