Answer:
This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.
Explanation:
The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.
