Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.

The answer would be natural selection.
The female deer might consider the large antlers of the male deer to show of certain genetic qualities that have a higher probability of reproduction, as well as a higher social status among deers.
This means that if she picks him as her mate during this season, their offspring will have a better chance of survival compared to her picking another deer with smaller antlers.
This is called natural selection because she will pick the deer that is most adapted to that environment. Thus their offspring can be ensured to have the highest possible probability to survive.
