Question

a volcanic island emerges from the ocean. based on succession principles, which sequence best describes the ecological development of this island?
climax community - pioneer species - intermediate species
intermediate species - pioneer species - climax community
climax community - intermediate species - pioneer species
pioneer species - intermediate species - climax community

Explanation:

Ecological succession on a newly formed volcanic island (primary succession) starts with pioneer species (like lichens) that can colonize bare rock. Over time, these modify the environment (e.g., create soil). Intermediate species (like grasses, shrubs) then establish. Eventually, a climax community (stable, complex ecosystem like a forest) forms.

Answer:

Pioneer species → intermediate species → climax community
