Amountain lion population recently experienced a drop in population size. which of the following would best describe the limiting factor that is involved? a change occurred in the genetic variability. the deer population experienced a rapid decline due to a parasite. mountain lion hunting experienced an increase in restrictions. the population of trichinella, a parasite, experienced a decline.

A mountain lion population recently experienced a drop in population size. The best  limiting factor that is involved is- The deer population experienced a rapid decline due to a parasite.

Only this could be the best possible answer out of all other options because when there are no deer, there is no food for the lions.

The correct answer is option B, The deer population experienced a rapid decline due to a parasite

Explanation:

As the prime food of lion in the jungle is deer, so if the population of deer is to be considered as declining , there will be some certain amount of negative impact on the population of lion as well.

The parasite attacking the deer causes their death , due to which very few deer are available as food to the lions thus the lions reach a stage of starvation after a certain period of time . In absence of food they may start dying as well thus the factor "The deer population experienced a rapid decline due to a parasite" is a limiting factor.
