What is exploitation competition? - ANSWERS-Type of competition that occurs indirectly

What is apparent competition? - ANSWERS-Type of competition that occurs between two
species preyed upon by the same predator.
Example: A species of spider and a species of beetle are both hunted by owls. If the amount of
spiders suddenly increase, this would lead to survival of more owls which would in turn hunt
