Match List - I with List - II and choose the correct answer from the given codes :List – I (Ecosystem types) List – II (Characteristics) a. Coral reefs i. Still water b. Deltas ii. Saline water c. Wetlands iii. Brackish water d. Rivers iv. Fresh water
Ecosystem Matching: Types and Characteristics
This solution provides the correct pairings between ecosystem types listed in List I and their defining characteristics from List II.
Coral Reefs: Saline Water
Coral reefs are marine ecosystems that flourish in specific oceanic conditions. They require warm, shallow, and clear waters with high salt content. Thus, their characteristic environment is saline water.
Match: a - ii
Deltas: Brackish Water
Deltas form at the mouths of rivers where freshwater meets saltwater. This mixing results in a unique environment characterized by brackish water, a mix of fresh and saltwater.
Match: b - iii
Wetlands: Still Water
Wetlands are areas saturated with water, often featuring still water or very slow-moving water bodies. This includes habitats like marshes and ponds.
Match: c - i
Rivers: Fresh Water
Rivers are natural flowing watercourses primarily composed of fresh water. They move towards larger bodies of water.
Match: d - iv
Ecosystem Match Summary
The correct pairings identified are:
- a. Coral reefs corresponds to ii. Saline water
- b. Deltas corresponds to iii. Brackish water
- c. Wetlands corresponds to i. Still water
- d. Rivers corresponds to iv. Fresh water
The correct combination representing these matches is a-ii, b-iii, c-i, d-iv.
