Explanation:

Question (First Question: Biome Identification)

To identify the biome, we analyze each option:

• Swamp: Characterized by flat, poorly drained land near water, with woody plants (matches the description).
• Marine: Ocean - based, not dominated by woody plants near running water.
• Estuary: Where river meets sea, not defined by flat, poorly drained land with woody plants.
• River: A water body, not a biome dominated by woody plants in poorly drained land.

So the correct answer is A. Swamp.

• Option A: Wetlands can be used for crops (e.g., rice paddies) and can also experience flooding, so this is a valid effect.
• Option B: Only mentions a source of crops, ignoring the flooding aspect.
• Option C: Only mentions causing floods, ignoring the beneficial crop - related use.
• Option D: Wetlands are not primarily waste - water purifiers (that's more of a constructed wetland or specific treatment, not a general effect on humans).

So the correct answer is A. Both a source of crops and floods.

• Option A: Swamps are typically in flat, poorly drained areas near streams (matches their definition).
• Option B: Swamps are near water sources like streams, not away.
• Option C: Swamps are in flat (not sloped) areas with abundant plants.
• Option D: Swamps have woody plants, so non - woody areas are incorrect.

So the correct answer is A. flat, poorly drained area near streams.

Answer:

A. Swamp
