Answer 1

Answer commensalism

EXPLANATION

Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.

A. The food and other resources they required became scarce due to climate change

E Predators including humans, hunted and killed the population to a point that it could not recover

EXPLANATION

Dodo were flightless bird and were highly exploited by human. Since the Bird were flightless they were easy to catch by Predators such as human leading to their declining. While there were trees from which Dodo were in mutual relationship. The decline in these tree population and low reproduction rate is one of plausible reason for Dodo extinction
