study
Any place or location where living and nonliving things interact.
Ex… a forest, a lake, and a compost heap
ecosystem
biotic factors
The living parts of an ecosystem.
ex soil, wind, rock , water, and air and non living parts
abiotic factors
a group of animals, plants or other living things that share common characteristics and are able to reproduce.
species
group of organisms of the same species that live in a particular area.
Ex… all the bees in this species living together in one area form a
population
all the populations of different species that live and interact in the same place form a community.
Ex…In a pond ecosystem, tadpoles, mosquito larva, birds, and bushes all share the same
community
One species receives the benefit.
Ex… A bird’s nest in a tree.
commensalism
Both species benefit.
Ex…Flowers and butterflies
mutualism
One species benefits while one is harmed.
Ex… Mosquitoes and humans
parasitism
something an animal does usually in response to some type of external stimulus in order to survive. Hibernating during winter is an example of
Behavioral adaptations
are those that change the physical, outward features of an organism or species. A structural adaptation may result in an animal flying, swimming faster, running longer, or being more capable of hunting prey. We’ve all seen a cat’s eyes glow in the dark or reflect a flash of light.
structural asaptations
is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism
predation
is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.
