There are two types of agricultural crop residues<span>. </span>Field residues<span> are materials left in an agricultural field or </span>orchard<span> after the crop has been </span>harvested. These residues include stalks and stubble (stems<span>), </span>leaves<span>, and </span>seed<span> pods. The residue can be ploughed directly into the ground, or </span>burned<span> first. Good management of field residues can increase efficiency of </span>irrigation<span> and control of </span>erosion<span>. </span>Process residues<span> are materials left after the crop is processed into a usable resource. These residues include </span>husks<span>, seeds, </span>bagasse<span>, </span>molasses<span> and </span>roots<span>. They can be used as animal </span>fodder<span> and </span>soil amendment<span>, fertilizers and in </span>manufacturing<span>.</span>
Explanation:
The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs
