Factors controlling biodiversity on different seabed substrates (rock, sand, mud) in coastal zones?

• A. Substrate type determines habitat complexity and shelter; food availability and oxygen content; movement and sediment stability; rocky shores support sessile organisms, sandy shores support motile and burrowing species, mud supports deposit feeders and detritivores.
• B. Substrate type has no effect on biodiversity
• C. Biodiversity is uniform across rock, sand, and mud
• D. Only depth matters, not substrate type

Answer: (A)
