The document discusses the biotic and abiotic factors of the ocean ecosystem. The biotic factors include various fish, sea snakes, jellyfish, sharks, coral, octopi, narwhales, puffer fish, sea horses, crab, seals, otters, starfish, and mollusks. The abiotic factors consist of water, rocks, sea shells, bones, pearls, sand, sunken ships, and teeth. These biotic and abiotic factors work together, with water helping fish swim and sand providing habitat for crabs. Interruptions to the food chain could hurt fish populations and impact fishing industries.
