valentinak56 [21]

Answer:

The correct answer is- Resource partitioning

Explanation:

According to the competitive exclusion principle, two species can not share the same niche because species that share the same niche have the same needs which leads to the interspecies competition.

This competition leads to resource partitioning which means the species who share the same niche evolved by natural selection to occupy different niche by dividing their resource which leads to the coexistence of two different species.

So here coexistence of wild cats differ in the size of their canine teeth is the result of resource partitioning.

The chemical energy of these plants all started with what energy source?
Zielflug [23.3K]

Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

  • green plants manufactures their food using sunlight.
  • in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.
