the largest number of individuals
limiting factors- factors that limit the type of life forms able to live in a ocean environment include temperature, sunlight,pressure,oxygen concentration and nutrient availability.
a shark and catfish are two organisms in the ocean that have a predator/prey relationship. if theres no small fish in the ocean then catfish would die and the shark wont have anything to eat and it will die.
a producers makes its own food then gets eaten by a consumer.
a consumer is an organism that feeds off of plants and gets eaten by a decomposer.
a decomposer is bacteria or fungus that breaks down cells from dead organisms.
producers are the most important things because they get energy from the sun and make there own food.
food chains and food webs
food webs are more realistic than food chains because they have more animals than food chains.
definition:the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
formula: 6CO2 + 6H2O ------> C6H12O6 + 6O2
definition: a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus.
some plants in the ocean move towards the sun which is tropism.
the plants help other fish to live because they eat plants.
decomposers are helpful in the ocean by cleaning all dead eaten plants or animals.
without decomposers the ocean would have a lot of dead animals and plants on the bottom.
