1. The correct description of succession is: The changes in species composition in a community over time as species colonize an area.
Succession refers to the gradual process of change in the species structure of an ecological community over time. This process occurs as different species establish themselves in an area, leading to a series of predictable changes in the ecosystem. Primary succession occurs in an area where no soil exists, such as after a volcanic eruption, while secondary succession occurs in areas where soil is already present, such as after a fire or farming activities.
2. Incorrect: The reduction in biodiversity of an ecosystem over time.
This description does not accurately capture the concept of succession. Succession is about the changes in species composition and diversity in an ecosystem as it progresses through different stages, rather than a reduction in biodiversity.
Understanding the concept of succession is essential in ecology as it helps us comprehend how ecosystems develop and evolve over time. I hope this explanation clarifies the meaning of succession for you. If you have any more questions or need further clarification, feel free to ask!
