A.Poisonous plants killed off many moose
B. Many moose reached old age and died
C. Overcrowding caused competition in moose population
D. A decrease in predators caused competition in moose population

Answer 1

Answer:

The option C is the correct option. The population of moose decreased after 1995 due to the overcrowding leads to competition in moose population.

Explanation:

• In the graph before 1995, the population of wolves decreased and the population of moose increased.
• As the population of moose increased, so the need for food and the shelter also increased.
• This created the competition between moose population for food and shelter.
• Many of moose population which cannot compete die due to less availability of food and shelter.
• That is why the population of moose suddenly decreased.
