Identify the key term described.


The relationship that results when organisms in an environment rely on each other for resources

A change in one species that results from a change in another species with which it interacts

Answer 1

1) Interdependence (ecological interdependence) — organisms in an ecosystem rely on one another for resources; when the reliance is mutually beneficial this is called mutualism (a form of symbiosis).

2) Coevolution — an evolutionary change in one species driven by a change in another species with which it interacts.
