Question

Zooxanthellae are (1pts) an invasive species of kelp in the Indian Ocean symbiotic algae that provide corals with energy via their photosynthetic activity symbiotic bacteria that decompose tissues of dead animals in oceans symbiotic bacteria that fix nitrogen in oceans an endangered species of fish in the Pacific Ocean Red tides are caused by (1pts) nutrient upwelling the position of the moon nutrient pollution leading to marine algae blooms increased ocean oxygen content increased ocean carbon dioxide content

Explanation / Answer

Answer 1: Option B: Symbiotic algae that provides corals with energy via their photosynthetic activity.

Zooxanthellae are algae belonging to phylum Dinoflagellata that depend on corals for protection from predators and fishes along with extraction of useful compounds necessary for photosynthesis. The Zooxanthellae in return perform photosynthesis and provide nutrition to corals.

Note: Zooxanthellae also have a symbiotic relationship with other marine animals like jellyfishes, molluscs and sea anemones among others.
