Explanation / Answer

Answer(2): Polyps are invertebrates in the phylum mollusca.

Hence the correct option is (c).

Answer(3): Biomass refers to the "weight" of organisms.

Hence the correct option is (a).

Answer(5): Salt marshes and mangroves are tidal.

Hence the correct answer is (a).

Answer(6): Salt marshes are dominated by all of the below except dwarf shrubs.

Hence the correct option is (d).

Answer(10): Holdfast is a part of a macroalgae.

Hence the correct option is (a).

Answer(11): Spatial heterogeneity can be defined as the amount of differing structure in an area.

Hence the correct option is (a).
