Which of the following was most likely the first stage of succession in the development of a forest ecosystem?
A
Pioneer species colonizing bare soil
B
Establishment of a mature forest
C
Development of a climax community
D
Introduction of herbivores
Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Recognize that succession typically begins with the colonization of a new or disturbed area by pioneer species, which are the first organisms to colonize bare or disturbed environments.
Identify that pioneer species are usually hardy species that are able to withstand harsh conditions and begin the soil formation process, making the environment more suitable for other species.
Consider that the establishment of a mature forest and the development of a climax community are later stages in succession, occurring after pioneer species have modified the environment.
Acknowledge that the introduction of herbivores is not typically the first stage of succession, as it usually occurs after plants have established themselves in the ecosystem.
