  1. 1. A group of the same kind of living things that live in the same place at the same time. For example, all the deer in a forest make up a deer population.
  2. 2. An animal that eats only meat, like a lion or a shark.
  3. 5. All the different kinds of plants, animals, and other living things that live together in the same area and interact with each other.
  4. 6. A place where living things (plants, animals, and microorganisms) and non-living things (water, air, soil) work together.
  5. 8. The study of how living things interact with each other and with their environment.
  6. 9. Living things, like plants, that can make their own food using sunlight or chemicals.
  7. 13. All the parts of Earth where life exists, including land, water, and the air.
  8. 14. The total amount of living matter in an area, like all the plants, animals, and microorganisms combined.
