ecosystem The living and non-living parts of the environment in a specific area. (Ecosystems can be really small or really large!)
ecology The study of how living things are related each other and to their natural environment.
Environment Everything that surrounds an organism and influences it. The study of how living things are related each other and to their natural environment.
Biotic Factors The living parts of an ecosystem such as plants and animals.
Abiotic Factors The non-living parts of…
a symbiotic relationship in which both species benefit from the association(win/win)
any relationship in which two species live closely and interact
occurs when one species benefits from the association while the other is neither helped nor harmed(win/whatever)
occurs when one organism lives on or inside another organism and harms it (win/lose)
An organism that eats other organisms to live.
The organism that gets eaten.
a single living thing
living factors in an ecosystem
The non-living parts of an ecosystem such as soil, climate and rainfall.
a system formed by the interaction of a community of organisms with their physical (abiotic) environment
...organisms that use sunlight directly to make food through a process called photosynthesis.
...organisms that eat producers or other organisims for energy
organisims that get energy by breaking down theremains of dead organisms.
animals that feed on the bodies of dead organisms.
..., A consumer that eats only plants.
..., An animal that eats other animals
..., An animal that eats both plants and animals
..., A series of steps in which organisms transfer energy by eating and being eaten
..., A community of organisms where there are several interrelated food chains
..., A diagram that shows the amount of energy that moves from one feeding level to another in a food web
...when resources such as food, water or space become limited, Anything that limits (restricts) the size of a population
...when two or more individuals or populations try to use the same limited resource such as food.
the components of an ecosystem (biotic or abiotic) that an organism needs that are currently present
an organism that is non-native and harmful to the ecosystem
how the reintroduction or removal of a signal organism can cause changes to the rest of the population
predator-prey population cycle
how predator and prey cause each other's populations to continuously cycle up and down
Plants use the sun's energy to convert water and carbon dioxide into sugars
the process by which cells use oxygen to release stored energy from food
main energy source that organisms use for most of their work (i.e. moving, growing)
cycling of matter
series of steps or cycle that allows abiotic elements to be used over and over again
flow of energy
energy (usually sunlight) transformed to chemical energy by autotrophs, all eventually lost as heat
A group of individuals that belong to the same species and live in the same area
A simple sugar that is an important source of energy.
all energy systems and trophic levels on earth begin with this main energy source
