Biotic components or biotic factors are any living organisms that affect another organism. These components shape an ecosystem which includes animals that consume organisms in question and its living food that the said organisms consume. Biotic components include human influence. Producers, consumers and decomposers usually comprise biotic components.
The biotic component of an environment are (a) plants and animals because only plants and animals are living
Biotic components are the living parts of an ecosystem. They include plants, animals, bacteria, and fungi. Biotic components interact with each other and with the abiotic components of the environment.

Answer:
a keystone species
Explanation:
A keystone species is a species that plays a key role in the balance of the entire ecosystem. Some examples of keynote species that are critical for their ecosystems include sharks, African elephants, sea otters, etc. The most important feature that defines a keynote species is the fact that these species have a huge influence on the food web dynamics. Moreover, keystone species are also characterized by a low functional redundancy (ie., they cannot be replaced by other species within the ecosystem).
