Question

question 5 of 10
why does competition happen?
a. there are limited resources in an ecosystem.
b. there are no predators in an ecosystem.
c. different organisms have different needs.
d. organisms do not need the same resources.

Explanation:

Competition occurs when organisms vie for the same limited resources (like food, water, space) in an ecosystem. Limited resources drive competition. Option B is incorrect as predators can be part of an ecosystem and competition still occurs. Option C is not the direct cause - different needs don't lead to competition unless resources are limited. Option D is false as organisms often need similar resources (e.g., multiple species needing water in a dry area).

Answer:

A. There are limited resources in an ecosystem
