What Type(s) of Microbial Interactions Take Place in a Microhabitat

Question

What type(s) of microbial interactions take place in a microhabitat?
A) antagonism
B) cooperation
C) competition
D) antagonism and competition
E) a combination of antagonism, cooperation and competition

Accepted Answer

Microbial interactions in a microhabitat can involve antagonism, cooperation, and competition. For example, one species may produce a compound that inhibits the growth of another species (antagonism). Alternatively, two species may work together to break down a complex substrate, such as cellulose, into simpler molecules (cooperation). Finally, multiple species may compete for the same resources, such as a limited supply of nutrients. Therefore, a combination of antagonism, cooperation, and competition occurs in a microhabitat.
