ecosystem: contains all living and non living parts of the environment in a given area
biotic:living/ex:animals
abiotic:non living/ex:rock
habitat:the place within an ecosystem that provides the biotic and abiotic organisms need to survive
populations:a group of the same species in the same area at the same time
community:a group of populations at the same time.
symbiosis:a close long-term relation between two species it usually involves exchange of food
mutualism:both species benefit - example: honey bees pollinate acacia flowers as they collect nectar for their hives.Without pollinators such as these,Acacias could not produce seeds
parasitism:one organism(parasite) benefits and the other(host) is harmed. - example: a mosquito bites a human the human(host)gets harmed and infected but the mosquito(parasite) benefits from the humans blood.
commensalism:one specie benefits and the other is neither harmed or benefit. - example: a bird nesting in a tree has a place to raise its young.It neither harms nor benefits the tree
competition:interaction between two or more organisms that need the same resources at the same time
Niche:a way species interact with biotic and abiotic factors to obtain food.
predation:the relationship between the predator and its prey
prey:an organism caught and eaten by a predator
predator:an organism that haunts or kills other organisms
population density: the size of a population compared to the amount of space available
contains all living and non living parts of the environment in a given area this can increase the competition and make it easier for diseases to be transmitted.
carrying capacity: the largest number of individuals of one species that an ecosystem can support
if a population exceeded its carrying capacity the area will become over populated and good growing conditions or the disappearance of competing species
extinction: if all members of a population die
when a lot of individuals live closer the food will be less
