Answer

  1. Keystone species, as they produce large quantity of fruits, and their protection leads to conservation of animals dependent on them.

Explanation:

Keystone species are the critical species which have the large effect on the population of other species in the environment. 

They are important to the community as they affect the species number and helps in maintaining the structure of the ecological community. 

The population of other species depends on the population of keystone species e.g., figs acts as a keystone species, as it produces a large number of fruits and provides food for many animals. 

So helps in increasing their survival rate.
