✔ L.3 Ecosystems Flashcards
non-living; often used to refer to the nonliving components of an ecosystem (such as climate and temperature)
abiotic
feed on other organisms (plant or animal) because they cannot make their own food, a heterotroph
Consumer
a community of different but interdependent species and their non-living environment.
Ecosystem
a hierarchy of food relationships from the simplest to most complex
Food Chain
animals
Fauna
plants
Flora
the immediate space where an animal or plant lives and has food, water and protection
Habitat
a living thing that produces its own food within itself, usually by using sunlight energy in photosynthesis; an autotroph
Producer
all the living factors (disease, parasitism, predation) that impact an organism
biotic factors
a division based on climate, plants and animals; an environment that has a characteristic type of climax community ex. Freshwater biome—all of the lake, pond, stream, & river communities on Earth
Biome
is the maximum number of organisms the resources of an ecosystem can support
Carrying Capacity
Note: The carrying capacity of the environment is limited by the available abiotic and biotic resources (limiting factors), as well as the ability of ecosystems to recycle the residue of dead organisms through the activities of bacteria and fungi.
a stable community that is in final stage of succession
Climax community
a form of symbiosis in which one organism benefits and the other is not harmed
Commensalism
the living part of an ecosystem composed of many species
Community
the type of interaction among organisms; the struggle to obtain needed resources like food, water, shelter
Competition
