Question

Algae—clam—sea star. This food chain would likely be found

a. in the photic zone.
b. in the intertidal zone.
c. in the benthic zone.
d. in the open ocean.

Answer 1

The food chain consisting of algae, clam, and sea star would likely be found in the intertidal or neritic zones, where sunlight penetration allows for photosynthesis, supporting the presence of algae.

Step-by-step explanation:

The food chain Algae—clam—sea star indicates the presence of photosynthetic organisms, meaning it would most likely be found in a marine zone where light penetration allows for photosynthesis. Algae are photosynthetic organisms, and such a food chain would depend on light for the initial energy input.

The photic zone extends to a maximum depth of 200 meters (656 feet) below the surface of the water, which is where enough sunlight penetrates for photosynthesis to occur. The neritic zone is well-illuminated and extends to about 200 m at the edge of the continental shelf, also enabling photosynthesis. Combining this information indicates that the food chain mentioned would most likely be found in the intertidal zone or the neritic zone, as these zones support photosynthetic life forms.
