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.

Respuesta :

This shift in the biological composition of a community over time is called succession.

The process by which a region's species and habitat mix changes over time is referred to as ecological succession. These communities gradually replace one another until a "climax community" is reached, such as a mature forest, or a disturbance occurs, such as a fire. Ecological succession is a fundamental concept in ecology. The first species to appear in a new environment are mosses and lichens.

They prepare the ground for larger species to grow, such as grasses, shrubs, and, eventually, trees. Ecological succession is essential for the growth and development of an ecosystem. It begins colonization of new areas as well as recolonization of areas destroyed by biotic and climatic factors. As a result, organisms can learn to adapt to changes and survive in a constantly changing environment.
