Question

dinoflagellates have endosymbiotic relationships with corals. corals cannot produce photosynthetic pigments, but they receive photosynthetic products from dinoflagellates. which of the following might explain why corals are damaged or destroyed by excessive turbidity of ocean waters? the increasing temperatures cause dinoflagellates to expel their chloroplasts. increased particulates prevent dinoflagellates from entering the coral. turbid waters block sunlight from reaching photosynthesizing dinoflagellates. dinoflagellates are unable to filter out nonorganic particulates during feeding. corals cannot see their prey in the turbid water.

Explanation:

Coral - dinoflagellate symbiosis is crucial for coral health. Turbid waters block sunlight needed for dinoflagellates' photosynthesis. Without proper photosynthesis, the symbiotic relationship is disrupted, harming corals.

Answer:

Turbid waters block sunlight from reaching photosynthesizing dinoflagellates.
