- Adaptation
- structure or behavior that helps an organism to survive in its habitat
- Decomposer

- Soil

- Environment
- surroundings of an organism that affect its life and development
- Sand
- small particles of various minerals and broken rocks, the result of weathering and erosion
- Fossil
- evidence of an organism from the distant past; can be actual plant or animal (frozen wooly mammoth meat), the preserved remains (dinosaur bones) or the impressions of its body
- Habitat
- the place where an organism lives. It provides food, air, water, and space for living and shelter

- a predictable sequence of growth, reproduction and death in organisms. Many plants grow from seeds. Most plants reproduce by growing flowers, which make more seeds and die. Animals begin as embryo and may go through metamorphosis on their way to adulthood, reproduction and death.
- Streak
- color of powder left on a surface after the mineral has been rubbed on it
