Answer 1

Answer: (C)

Benthonic and brown algae

Answer 2

Marine ecosystems encompass about 71% of the Earth's surface, holding approximately 97% of the world's water. These ecosystems contribute significantly to the planet's total net primary production, accounting for 32% of it. Depending on factors such as water depth and shoreline characteristics, marine ecosystems can be categorized into various zones. The benthic zone, which encompasses substrates beneath the water's surface, provides habitat for numerous invertebrate species. Marine ecosystems host diverse classes of organisms, including brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Additionally, the fishing industry relies heavily on marine ecosystems, as they serve as the primary source of commercial seafood harvested from wild populations.

So, the correct option is (C): Benthonic and brown algae
