Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
Svetlanka [38]

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
