Lesson 6

Question 1

ecological succession

Answer 1

Ecological succession is the observed process of change in the species structure of an ecological community over time.

Question 2

pioneer species

Answer 2

Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.

Question 3

pioneer community

Answer 3

In biology, the variety of plants, animals and fungi that first colonize a barren habitat is known as a pioneer community. These organisms are the first in the order of biological succession for that habitat and are followed first by seral communities and then by climax communities.

Question 4

climax community

Answer 4

In ecology, climax community, or climatic climax community, is a historic term that expressed a biological community of plants, animals, and fungi which, through the process of ecological succession the development of vegetation in an area over time, had reached a steady state.
