ecology
Term
What is a particular environment and all the living things that are supported by it?
Definition
ecosystem
Term
This element is the "backbone" for all living things. It is not a living organism without it.

Term
What must first occur in the atmosphere before we can use nitrogen later?
Definition
lightning
Term
Rain carries nitrogen down to the soil, how else is nitrogen put back into the soil?
Definition
bacteria digests dead matter and releases nitrogen into the soil

secondary consumer
Term
Is energy lost or gained as you go up the energy pyramid?
Definition
energy is lost

Definition
sugars (in addition to oxygen and water vapor)
Term
What do we call the process whereby the plants use the sun's energy to produce food?
Definition
photosynthesis
Term

Definition
producers (plants)
Term

dead leaves, dead roots, dead branches, dead animals
Term
Water vapor that is cooled, gets close together, and often forms clouds is called what?
Definition
condensation
Term
What is respiration?
Definition
the release of water vapor into the air by animals
Term
What do we call the release of water vapor into the air by plants?
Definition
transpiration
Term
Water changing into water vapor because of increasing temperatures is called what?
Definition
evaporation
Term
When water vapor condenses and cools down enough, what part of the water cycle occurs next?
Definition
precipitation
Term
What is runoff?
Definition
water flowing down mountains, hills, or slopes in the form of rivers or streams
Term
Why do we get less energy from eating a rabbit after the rabbit has eaten carrots?
Definition
Because the rabbit has burned off some of the energy by running, moving about, giving off body heat, etc., etc.
