nonliving factors in an ecosystem

living factors in an ecosystem

all the living and nonliving factors in an area

the organism at the top of the food web that is NOT hunted

organisms that use photosynthesis to make their own food

the variety of life across all levels of ecological organization

organisms that eat meat

the largest population that an environment can support

a type of symbiosis where one organism benefits and the other organism is unaffected

the populations of organisms of different species in a specific are at a given time

when more than one organism tries to use the same limited resources - only the organisms able to get the resources they need to survive

animals that can't make their own food so they must consume or eat it

organisms that feed on the remains or wastes of other organisms

a series of steps in which organisms transfer energy by eating and being eaten

a system of several overlapping food chains; shows a complete picture of the flow of energy in an ecosystem

animals that eat plants

organisms that MUST eat other organisms that make their own food

environmental factors that cause a population to stop growing or decrease in size

a type of symbiosis where both organisms benefit

animals that eat both plants and meat

a type of symbiosis where one organism benefits and the other organism is harmed

the process by which plants use energy from the sun to make food and oxygen

comprised of ALL the individuals of the SAME species in an area at a given time

type of feeding relationship in which one animal captures and eats another animal for food

an animal eating the prey also a limiting factor in an ecosystem

an animal that is being eaten by another

these organisms feed directly on a producer

organisms that are able to produce their own food through photosynthesis using the sun's energy

organisms that eat the remains of dead organisms

these organisms eat primary consumers

close relationship between two species

these organisms eat secondary consumers

In densely populated areas diseases and parasites would spread very quickly causing devastations in the ecosystem
