Question

the picture shows the growth in an abandoned park over a few years. at which point will the park likely become a climax community?
○ after 1 year
○ after 3 years
○ after 8 years
○ after 20 years
1-2 years 3-5 years 6-20 years

Explanation:

A climax community is a stable, mature ecological community. Succession in the park shows early stages (1 - 2 years: pioneer, 3 - 5 years: grass), and 6 - 20 years leads to a more complex community (like the bush). After 20 years (end of 6 - 20 years) is when it likely stabilizes as a climax community, as earlier times (1, 3, 8 years) are still in successional stages (1 - 2: pioneer, 3 - 5: grass, 8 years: still in 6 - 20, not fully matured yet).

Answer:

after 20 years
