You sample the solid waste of three infants from three different families each week for 24 weeks. You find that the population of bacteria in the gut is dominated by one species for the first 12 weeks, and then shifts to another species. This shift in the biological composition of a community over time is called:
A)competition.
B)mutualism.
C)succession.
D)evolution.
E)ecology.

Quizplus · Accepted Answer

Succession refers to the process of biological communities changing over time. In this scenario, the gut bacterial community shifted from one dominant species to another, indicating succession. Competition refers to the interaction between organisms competing for limited resources. Mutualism refers to a type of symbiotic relationship where both organisms benefit. Evolution refers to the process of genetic changes in a population over time. Ecology is the study of interactions between organisms and their environment, but it is not specifically related to the concept of community succession.
