The Ocean Ecosystem
Dolphin, Shark, Sea Turtle, Jelly Fish, Sea Horse, Whale, Seal, Kelp, Sea Weed, and Guppies are all Biotic factors of the ocean
Sand, Salt Water, Rocks, dead oranisms, and Sea Shells are all abiotic
Carrying capacity maximum population size of the species that the environment can sustain indefinitely, given the food, habitat ,water, shelter, and other necessities available in the environment.
A limiting factor in a system is an input or variable such that a small change in it from the present value would cause a non-negligible change in an output or other measure of the system.
Decomposers - Bacteria & Fungi, gets energy from dead organisms
Consumer - Fish, gets energy from seaweed
Producer - Seaweed, gets energy from sun
Herbivore - A organism that only eats plants
Carnivore - A organism that only eats meat
Omnivore - A organism that eats both meat and plants
Scavenger - A organism who feeds off dead animals.
If you remove a population from the ocean then food source would be low and many animals would starve.
