how does access to sunlight affect the biodiversity of a river ecosystem?\na. sediment is limited in areas with little access to sunlight.\nb. plant and animal life is limited in areas with little access to sunlight.\nc. algae is more common in areas with less access to sunlight.\nd. biodiversity is unaffected by access to sunlight.\n\nplease select the best answer from the choices provided\n\na\nb\nc\nd
Answer
Brief Explanations:
Sunlight is critical for photosynthetic organisms (like algae and aquatic plants) which form the base of the river ecosystem's food web. In low-sunlight areas, these producers cannot thrive, which in turn limits the animal life that depends on them, reducing overall biodiversity. Option a is incorrect because sediment levels are not directly limited by sunlight. Option c is wrong because algae need sunlight to grow, so they are less common in low-sunlight areas. Option d is incorrect as sunlight directly impacts the base of the food web, thus affecting biodiversity.
Answer:
b. Plant and animal life is limited in areas with little access to sunlight.
