Question

questions 1 through 3 refer to the following.

3 mark for review

which of the following claims is best supported by the data in the graph?

a the temperature of earth rises and biodiversity increases immediately after a volcanic eruption.

b the carrying capacity of plants in the area is approximately 250 species.

c after the volcanic eruption, pioneer species colonized the area and the ecosystem began to undergo succession.

d plant species that are well adapted will survive and reproduce, leading to a change in the ecosystem biodiversity through the process of natural selection.

Explanation:

• Option A: The graph shows plant species number changes post - eruption, not temperature and biodiversity.
• Option B: The carrying capacity is not indicated as 250 in the graph.
• Option C: After volcanic eruption, pioneer species colonize (succession starts as shown by the increase in species number over time).
• Option D: The graph focuses on species number change (succession) rather than natural selection.

Answer:

C. After the volcanic eruption, pioneer species colonized the area and the ecosystem began to undergo succession.
