an organism that is able to make its own food through the process of photosynthesis

an organism that gets its energy from eating other organisms

an organism that hunts and kills another organism for food

an organism that is hunted and eaten by a predator

an organism that breaks down dead organisms and waste

the process in which dead organisms are broken down and returned to the soil

shows the path of energy from one organism to another

many overlapping food chains linked together

the environment where an organism lives; its "home"

the surroundings/area where an organism lives

all of the same type of organisms living in an environment

all of the populations living together in the same environment

the living and nonliving parts of an environment

living things depending on each other

a characteristic that helps an organism survive in its environment

the seasonal movement of animals from one place to another

an animal’s body processes slowing down for survival in extreme conditions

new organisms that come from a parent organism

A characteristic that is passed from parents to offspring is an inherited trait.

A characteristic that an organism learns by observing other organisms or is taught

a behavior that is inherited; an organism is born knowing how to do this

the stages of growth and development that an organism goes through during its lifetime

the changes that insects and some amphibians go through during their life cycle

4 stages in life cycle: egg, larva, pupa, adult

3 stages in a life cycle: egg, nymph, adult

a population that is greater than the resources available in an ecosystem

the complete dying out of an entire species

the movement of carbon dioxide and oxygen on Earth by the processes of respiration and photosynthesis

a process by which animals use oxygen and food to make energy and carbon dioxide

the population size that an environment can feed and

support

a gas produced by animals during respiration that plants use for photosynthesis

apart of the ecosystem that is not living, such as sunlight, air, and water

the process in which plants use energy from the sun to make their own food

an animal that only gets energy by eating only plants

a long-term relationship between two different kinds of organisms where one or both receive benefits

a gas produced by plants during photosynthesis that animals use for respiration

an animal that gets its energy from only eating other animals

a part of an ecosystem like a plant or animal with basic needs that must be met

an animal that gets energy by eating both plants and animals

a group of organisms with similar characteristics that allow them to reproduce

the role an organism plays in its environment

the resemblance of an organism to another organism or to its surroundings that gives it a better chance at survival

a mark or depression made by pressure

to remain alive or in existence; live on
