Ecosystem an area where plants, animals, and other organisms, co-ordinate for their living. According to energy pyramid, ecosystem can support fewer foxes than grasshoppers.
<h3>What is energy pyramid?</h3>
Energy pyramid is the flow of energy from one tropic level to another which is always erect.
After each level, 90% energy is lost in environment as heat. There is loss of energy at each tropic level.
As foxes comes after grasses in energy pyramid, so the ecosystem can support fewer foxes than grasshoppers.
Thus, the correct option is A.
