Correct Answer: Option D
Explanation:
The correct answer is D: Succession.
Explanation:
Succession refers to the process by which an ecological community undergoes a series of changes in species composition over time. This process can be observed in a cleared plot, where organisms gradually colonize the area in a particular order, starting with pioneer species and eventually leading to a stable community or climax community.
Here's why the other options are not correct:
- A. Ecosystem: An ecosystem is a system of living organisms interacting with their physical environment, but it doesn’t specifically refer to the process of species appearing in a particular order.
- B. Food chain: A food chain is a linear sequence of organisms through which energy and nutrients are passed by consumption, not the order of species appearance.
- C. Food web: A food web is a more complex, interconnected set of food chains in an ecosystem, again unrelated to the sequence of species appearing in a cleared area.
- E. Community: A community is a group of different species living in the same area, but it does not describe the order in which species colonize a new area.
Thus, succession is the correct term to describe the gradual process of species establishment and changes over time in an ecosystem.
