Question

on the aldabra islands off the coast of africa, tortoises only eat native shrubs that they can reach extending their necks. feral goats also eat the shrubs, but they can reach much higher than the tortoises. the result is that there is less vegetation that the tortoises can reach, and many starved to death (later, a feral goat control program was put into place). what type of relationship between tortoise and goat is this? predation interspecific competition mutualism commensalism

Explanation:

Both tortoises and goats eat vegetation. Goats' over - eating leads to less food for tortoises, which is interspecific competition.

Answer:

Interspecific competition
