Explanation:

Question 8

Wetlands have ecological functions. Trapping and filtering pollutants (A) is a known wetland function (e.g., via vegetation and soil). Reducing flooding (B) is also a function (absorb excess water). Adding nutrients (C) is not a primary function (wetlands filter, not add excess nutrients). Controlling sunlight (D) is not a wetland function. But if we assume a single correct option (maybe a typo, but likely A or B; if forced to pick one, A is a key filtration function). However, maybe the question expects multiple, but as a multiple-choice with options, likely A.

Plankton (A) are organisms that float near water surfaces (includes phytoplankton, zooplankton). Starfish (B) are benthic (bottom-dwelling) or move on seafloor. Squids (C) are active swimmers (nekton). Sponges (D) are benthic. So the correct answer is A.

Bottom - dwelling organisms in a body of water are called benthos. These organisms live on or in the substrate of the water body, including organisms like some worms, mollusks, and crustaceans that are adapted to the benthic (bottom) environment.

Answer:

A. Trap and filter pollutants
