If an apex predator enters an ecosystem which level of the food Petra is will benefit?
The one above the apex predator
The one below the apex predator
The lowest level of the food pyramid
The one below the apex predators prey

The correct option is D) The one below the apex predators prey

Explanation:

An apex predator can be described as a predator animal which is at the top pf a food chain. This means that the apex predator does not have a predator of its own.

Option A cannot be true because there will be no predator for the apex predator.

Option B cannot be correct because the organisms below the apex predator will not be benefited. There population will decrease because of the apex predator.

However, as the population of the apex predator's prey will decrease, the organisms below the prey will increase as they will have lesser predators,. Hence, the correct option is D.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
