Explain the role of water availability in hydrosere succession.
Model answer
What a good answer should say
- Water availability is crucial in hydrosere succession as it influences the types of vegetation that can establish and thrive.
- In aquatic environments, the initial colonizers are typically submerged plants, which gradually lead to the development of emergent vegetation as sediment accumulates and water levels decrease.
Explanation
Why this works
This works because it directly answers the comparison in the question and keeps the explanation linked to Ecosystems under stress. A strong response states the key difference clearly, then explains why that difference matters for the biology.
