Many plants, such as the potato plant, avoid insect predation by producing highly toxic sap. However, the potato bug, unlike mos
t insects, has adapted to the toxins and can still eat the potato plant. In turn, over a long period of time, potatoes are likely to develop more chemical defenses against the potato bugs. This type of consistent adaptation between two species is known as
A) co-evolution.
B) commensalism.
C) a realized niche.
D) a fundamental niche.
