Question

which of the following most accurately describes how competition can impact populations in an area?
competition impacts only one species, regardless of available resources.
competition does not impact the species when resources are limited.
competition can impact the population of both species when they are in direct competition for limited resources.
only one species can be impacted by competition.

Explanation:

Competition occurs when two or more species vie for the same limited resources (such as food, water, or territory). In direct competition for limited resources, both species involved are affected. For example, if two bird species compete for the same type of nesting sites (a limited resource), the population growth of both can be impacted as they struggle to obtain the necessary sites for breeding.

• The first option is incorrect because competition is not one - sided when resources are involved.
• The second option is wrong as competition is more intense when resources are limited, not non - impactful.
• The fourth option is incorrect because in a competitive interaction over resources, usually more than one species (the competing ones) is affected.

Answer:

Competition can impact the population of both species when they are in direct competition for limited resources.
