with an increase in each trophic level, about 10% of energy is lost by the animals due to, respiration, excretion, and other metabolic processes.Can some one explain this part of the syllabus for me:
Explain why there is an increased efficiency in supplying green plants as human food and that there is a relative inefficiency, in terms of energy loss, in feeding crop plants to animals
In my notes the explanation is as follows"
If plants are fed to animals, and the animals are then eaten, it is less efficient than directly eating the plants, because the animal hasn’t used up some of the plants energy, allowing plants to feed more people.
Thus it is more efficient to consume on green plants rather than animal food for, only 10% of energy provided by plants would be attained through thd animals.
hope this helps...
