Question

What causes competition in an eco system?

Answer 1

Answer: Competition in ecosystems.

Step-by-step explanation:

Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live.

Answer 2

Increasing members in the higher trophic level causes competition in an ecosystem.

Step-by-step explanation:

For example, if there is a shortage of producers, the primary consumers will face a higher competition for food. Thus, many will die. Death of primary consumers will increase the competition in secondary consumers as they are left with less food options. This will go on till the tertiary consumer, and the competition will continue until each trophic level is balanced.
