abiotic factors





carrying capacity and changes in populations

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.

food,water,shelter,and space

because there are new things that may come to the specific ecosystem and some animals are becoming extinct  

limiting factors and predator/prey relationships

limiting factors: the factors that prevent a population from growing any larger

algae growth

shark and dolphin

energy roles

Producers: a organism that makes its own food


herbivores: a organism that gets its energy from plants, and only plants

Sea turtles

omnivores: a organism that eats both plant, and animal orgins


Carnivores: a organism that eats meat, and only meat

Killer whale

Decomposers: a organism that decomposes organic material.

Sea mushroom

Scavengers: an organism that feeds off of dead material


because it is the source to all the levels of

zooplankton,young urchids,and copepods

food chains and food webs

 Food webs are more important because they show more, different overlapping paths that shows one organism may eat more than one organism. If one organism is extinct from the food web, then the other organism that eats it can still devour another organism in their following food so they can survive, but the balance of the food web will still be broken, just not as quickly as the food chains.

why removing a population is bad is because it could mess up the whole population cycle

trophic levels and energy pyramids

why a pyramid is better than any shape is that it shows what the lower steps are going to lead up to

why producers are on the bottom is because there are more of producers and less of top predators
