The average temperature is around 74 degrees Fahrenheit. Oceans do have seasons but it’s mostly

warm year round. They do not have precipitation because it’s under water. It’s location are in the tropical latitudes. Abiotic factors: temperature of

water, current strength, dissolved minerals.Biotic factors: fish mollusks, living coral, echinoderms.

Producer: an autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis.

Primary consumer: an animal that feeds on plants.

Secondary consumer: an organism that largely feeds on primary consumers.

Tertiary consumer: an carnivore at the top of the food chain that feeds on other carnivores.

Decomposer: an organism, usually a bacteria or fungus, that breaks down the cells of dead plants and animals.

Producers include algae, sea plants, plankton. Primary consumers are mostly small fish, molluscs, coral polyps, clams and sponges, which are eaten by secondary consumers like eels, crabs, starfish and octopus. Some decomposers are fan worms and flat eels.

Water cycle: the circulation of the earth’s water, in which water evaporates into the atmosphere, where it condenses and falls as rain or snow.

Carbon cycle, the circulation of carbon between living organism and their surroundings. Carbon dioxide from atmosphere is synthesized by plants into plant tissue, which is ingested and metabolized by animals and converted to carbon dioxide again during respiration and decay.nitrogen cycle: the continuous sequence of events by which atmospheric nitrogen and nitrogenous compound in soil are converted, as by nitrfication and nitrogen fixation, into substances that can be utilized by green plants and denitrification.

An evironmental issue is pollution. It’s a major problem over half the global ocean. It threatens animals and their homes
