Many plants, such as the potato plant, avoid insect predation by producing highly toxic sap. However, the potato bug, unlike most 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 reliazed niche.
D. a fundamental niche.

Commensalism is the relationship that exists between both potato plant and potato bug

Explanation:

Commensalism entails relationship between two organisms where one gains and the other does not either gain or lose. The analogy above shows that the insect potato bug gains from the plant but the potato plant does not gain nor lose as a result of this

the cell theory states that all living things including animals, as well as plants, are made of cells.
