ocean ecosystym #ecosys2






The maximum population size of the species in the oceans that can sustain giving the food, habitat,water and shelter.

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment. The Carrying Capacity for Great White sharks in the coast of Los Angeles is about 10, because the coast of L.A is not as big as other areas Great White's can live, the carrying capacity is less because that means less algae, which means less fish, which means less sharks, it goes down the whole food chain.

limiting factors:

The various organisms living in the sea are suitably adapted to temperatures at differing depths. Because sunlight can penetrate water to only about 100 feet, water temperature falls with the ocean's floor. Sunlight is not only important to water temperature, but is necessary for the production of oxygen and other important substances. The weight of the water exerting pressure on life forms in the ocean increases with depth, limiting life at increasing depths. Finally, supplies of nutrients often run short in different regions, with nitrogen being the primary limiting nutrient to saltwater life

energry rolls:

Producers- are also called autotrophs,they receive their energy from the sun,make their own food through photosynthesis,and provide the most energy that feeds the rest of the ocean ecosystem

Consumers- are also called heterotrophs, they don't make their own food,they feed on other organisms(plants and animals) ,receive their energy by consuming other organisms,and there are 4 types of consumers which are herbivores,carnivores,omnivores,and scavengers

these are some of what i have found for examples

Herbivores- lobsters,fish,sea urchins,Green Sea Turtles Carnivores- sharks,dolphins,killer whales,seals Omnivores- sea turtles,crabs,dolphins,lobsters Scavengers- zooplankton,sharks,marine eels,remoras

Decomposers- organisms that break down wastes and dead organisms and return the nutrients back into the environment. examples: shrimp,bacteria,nematodes,brittlestars

each of the energy rolls get their energy from the organism they consumed

Food Chains and Food Webs:

Food webs are more realistic than food chains because a food web shows multiple food chains,it shows that an organism doesn't just eat one organism in its ecosystem,and food chains only shows a path that only starts with one producer.

The producers are in the largest level because it has more energy that it gets from the sun which provides the energy to fuel the rest of the ecosystem and the top predators are in the smallest level because they have the least energy that it gets from the level before it


Carbon dioxide,water,and sunlight are needed for photosynthesis that will eventually produce glucose and oxygen.

Photosynthesis takes place in the chloroplast of the plant cell.The chloroplast contains chlorophyll which traps the sunlight so it can combine with carbon dioxide and water.


Tropism is turning or bending movement of an organism toward or away from an external stimulus,such as light,heat,or gravity.

Decomposers are vital in the ocean because they have to break down the dead organisms at the bottom of the ocean to get back the nutrients from them and give it off to the living organisms.

he adaptions purpose is to enable traits so organisms can survive in their ecosystem and there are two types of adaptations structural and behavioral;structural is the physical features of an organism and behavioral is how an organism acts.These adaptations help organisms survive by giving them the features and behaviors that are suitable for the organism in its environment.Adaptations that plants and animals need in the ocean environment are camouflage,poison/venom,traveling long/deep distances
