How does access to sunlight affect the biodiversity of a river ecosystem? a. sediment is limited in areas with little access to sunlight. b. plant and animal life is limited in areas with little access to sunlight. c. algae is more common in areas with less access to sunlight. d. biodiversity is unaffected by access to sunlight.

The correct answer to this question would be b. Plant and animal life is limited in areas with little access to sunlight.

The correct answer is option B

The access to sunlight helps in the development of the plants and animals. The area where more sunlight is available, will have large number of animals and plants.

The area that is deprived of  sunlight will have less animals and plants as compared to that of the area having more sunlight reaching the river.The phytoplanktons and zooplanktons will appear only in the area having more sunlight.
