Question

question 12 of 25
which freshwater ecosystem is most productive?

a. stream
b. swamp
c. creek
d. bog

Explanation:

Swamps are highly productive freshwater ecosystems. They have abundant nutrients from decomposing organic matter and support a diverse range of plant and animal life. Streams and creeks have flowing water which limits sediment and nutrient accumulation compared to swamps. Bogs are waterlogged but often have acidic conditions and lower nutrient availability (due to sphagnum moss dominance) reducing overall productivity relative to swamps.

Answer:

B. Swamp
