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.
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
shark and dolphin
Producers: a organism that makes its own food
herbivores: a organism that gets its energy from plants, and only plants
omnivores: a organism that eats both plant, and animal orgins
Carnivores: a organism that eats meat, and only meat
Decomposers: a organism that decomposes organic material.
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
