Study Notes
Adaptation
- A characteristic of an organism that helps it survive in its environment.
Axis
- An imaginary line an object rotates around.
- Earth's axis runs through the North and South Poles.
Change of State
- A physical change that occurs when matter changes form (solid, liquid, gas).
Chemical Change
- A reaction or change in a substance that produces a different chemical.
Community
- A group of different species living in the same geographical area.
Compound
- A substance made of two or more elements chemically bonded.
- Has properties unlike the individual elements.
Conservation
- Controlled use and/or maintenance of natural resources.
- Efforts to protect these resources.
Constellation
- A recognizable pattern of stars.
- Often named based on their shape or figure in the sky.
Consumer
- An organism that eats other organisms for food.
Decomposer
- An organism that breaks down dead organisms for nutrients.
Density
