why are swamps more productive than streams?
a. streams do not get enough sunlight.
b. streams are larger in size.
c. streams have too much water flow.
d. streams have water that is stagnant.

Explanation:

Swamps are more productive than streams. Streams have flowing water which can wash away nutrients and organic matter. Swamps have relatively stagnant water. Stagnant water allows for the accumulation of nutrients and organic matter. This accumulation provides a rich environment for the growth of plants and the support of various organisms, making swamps more productive.

Answer:

D. Streams have water that is stagnant.
