Answer:

Option D

Explanation:

in this food chain, it is clear that gray wolf feed upon Moose and the moose feed upon following primary food resources - a) Maple b) Balsam Fir c) Aquatic plants and d) cotton wood. Except Balsam, there are other organisms as well who are feeding upon Maple and Aquatic plants.  

Therefore, any change in balsam plants population is directly affected by change in population of Mouse.  

Now if the population of gray wolf is increased, they will feed upon mouse and hence the balsam fir will flourish to its full extent as the population of its only primary consumer i.e mouse will decrease.  

Hence, option D is correct

Rama09 [41]

Answer:

large mammals such as gorillas

Explanation:

The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.

There are three types of survivorship curves which can be constructed by studying the life history of the organisms.

The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.

Thus, large mammals such as gorillas are the correct answer.
