本题详细解析:
Niche: the set of rep, 3- -x-q 3ju.yenertnew y3isources, abiotic and biotic factors in which a species can survive and the interactions that it has with t3--.wiuejxqpn,n ye-tr 3 e y3hem.

Biotic factors: living parts of an environment, e.g. predators, prey, herbivores, competitors, and parasites amongst others.
Genetics: determines how a species looks and acts but does not describe the environmental conditions with which a species interacts.
