How are predation and competition essential for maintaining a thriving ecosystem?
Elis [28]

Answer:

<u>Both of these are necessary to maintain overpopulation of any species in an ecosystem.</u>

Explanation:

  • Predation is an act in which one organism eats another organism present in the ecosystem.

  • The one eaten is called prey, while the dominant organism is called Predator.

  • Since an ecosystem is made up of many organisms along with the natural resources present in it.

  • This gives rise to different species competing against one another.

  • If one of these species is at a certain advantage, their population will rise uncontrollably hence to prevent this a predator plays a major role.

  • On the other hand, competition is a term which describes the harm caused to two different organisms.

  • This is due to the limited number of natural resources like food, water or shelter etc.

  • Organisms who are less likely to adapt according to the changing environment ultimately die.

  • For example, Plant roots over time lessen the amount of nitrogen present in the soil, causing the neighboring plant to die.
