3. Is a group of individuals of the same species.
5. Can leave plants and animals submerged in water, thus altering their food chains.
6. includes all the populations that inhabit a common environment and interact.
7. Are caused when the amount of water necessary for living things to survive is not available. Many plants die because they cannot perform photosynthesis, as a result, consumers cannot obtain energy from them.
9. periods Are times when the global temperature of the earth’s surface decreases, which causes the migration of animals and the extinction of species that do not adapt to the new environmental conditions.

16. trophic level They feed on herbivores, they are called secondary consumers.
17. Feed on other animals but without killing them.
18. Like fungi and bacteria, feed on waste and the remains of living things of all trophic levels.

4. Unicellular or multicellular that belongs to a particular species.
8. They eat both vegetables and animals.
10. They are consumers, eat another animals
11. It's the interaction of living things but different species in an environment.
12. They are consumers, eat plants, leaves, flowers, fruit, pollen, nectar, seeds and roots.
