Information gathered by experiments and/or observations.
What is data
300
An area where living and non-living things interact with each other

What is carrying capacity
300
Each step in a food chain or web

Noticing events in a careful way.
What is an observation
400
The type species that is left standing at the end of succession

400
The process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers
What is transpiration
400
The saltiness or dissolved salt content of a body of water
What is salinity

An idea intended to explain something.
What is a theory
500
The type of succession where soil still remains after a disturbance
What is secondary succession

What is respiration
500
The zone of a body of water (ex: Lake or Ocean) that is exposed to sunlight
What is a photic zone
500
Organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition
