| Deforestation | An organism, such as bacteria or fungus, that breaks down dead matter and returns nutrients to the soil |
| Desert | lAn area that gets less than 25 centimeters of precipitation each year, making it VERY dry |
| Ecology | The study of how living things interact with one another and their environment |
| Ecosystem | All the living and nonliving things in an area and their interactions |
| Estuary | A body of water where fresh water and salt water ecosystems merge together |
| Fauna | The animal life in an area |
| Flora | The plant life in an area |
| Food Chain | The order in which animals feed on plants and other animals (shows how energy flows from producer-consumer-decomposer) |
| Food Web | Many food chains put together to show how energy flows through the ecosystem |
| Grasslands | A biome whose main plants are grasses |
| Habitat | The place and surroundings where an organism normally lives |
| Herbivores | An organism that eats only plants |
| Host | A living organism on which a parasite lives |
| Limiting Factor | Something in an environment that keeps the population of an organism from increasing as much as it could |
| Niche | The habitat that supplies everything needed for a species or an organism to survive The role that an organism plays in its environment |
| Nitrogen Cycle | The continuous series of processes in which nitrogen passes from the air into the soil, then into an organism, and then back into the air |
| Omnivores | A consumer that eats both plants and meats |
| Parasite | An organism that lives in or one another organism (host) |
| Photosynthesis | The process by which green plant cells make food from sunlight, water, and carbon dioxide |
| Pollutant | A substance that spoils, dirties, or damages some aspect of the environment |
