Question

Using Figure 5-2, what is the most likely cause of the decrease in moose populations immediately after 1995?

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

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

Step-by-step 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.
