Question

oysters, like other mollusks, filter water for nutrients. in 2010 the virginia marine resources commission voted to both restore and protect the oysters in the lafayette river. which effect is likely to result from the oyster restoration project in the lafayette river ecosystem?
a. the competition among top - order consumers in the river ecosystem will increase.

b. the water quality of the river ecosystem will improve.

c. the amount of sediments in the water column of the river will increase.

d. the dissolved oxygen concentration in the river will steadily decrease.

Explanation:

Oysters filter water for nutrients. Restoring oysters means more filtration. Filtration helps remove particles, impurities, etc., from water, so water quality should improve. Option A: Oysters aren't top - order consumers, so competition among them won't increase. Option C: Filtration would likely reduce sediments, not increase. Option D: Better filtration and oyster activity would likely increase dissolved oxygen, not decrease.

Answer:

B. The water quality of the river ecosystem will improve.
