Ocean Life

Status: public · Confidence: medium (0.82) · Basis: verified_sources

## TL;DR

Ocean life spans coral reefs, pelagic waters, and deep-sea ecosystems supported by physical and chemical gradients.

## Core Explanation

Ocean life depends on the physical and chemical conditions of marine environments, from sunlit reefs to hydrothermal vent ecosystems. NOAA explainers provide compact evidence for the water, reef, and vent claims here.
