Answer:

The correct answer is E. Biological.

Explanation:

The biological definition of species states that while two organisms can mate and have successful and fertile breed, then they belong to the same species. Therefore, if there were no genetic flow between both species, it means that mating and breeding were not successful and therefore, they were not the same species.

water
disease
health
relationships

Factors that control nature population growth:

- food
- shelter
- precipitation
- relationships
- food web
- weather ( natural disasters)

So as you can see humans pretty much has more control over our population growth while nature operates by cycle and a set of systems that man can't create, but can manipulate.
