which choice best describes why 90% of all marine organisms thrive/live in the photic zone, which is the portion of a body of water that receives light from the sun and interacts with the atmosphere?
the photic zone is where photosynthesis occurs, and animals need photosynthetic organisms for food.
the photic zone is a major source of carbon and nitrogen as nutrients for many organisms.
salinity and ph levels within the photic zone are most stable, enabling more organisms to live there.
all organisms need sunlight to live and they stay in the photic zone in order to gain the most sunlight possible.

Explanation:

The photic zone receives sunlight, enabling photosynthesis by primary producers (e.g., algae, phytoplankton). These producers form the base of the marine food web, supporting most marine organisms that depend on them for food.

Answer:

The photic zone is where photosynthesis occurs, and animals need photosynthetic organisms for food.
