UNIT 1 SCIENCE REVIEW

5. : Unicellular or multicellular that belongs to a particular species.
8. factors: They are always living things.
9. includes all the populations that inhabit a common environment and interact.
12. Like fungi and bacteria, feed on waste and the remains of living things of all trophic levels.
13. Feed on other animals but without killing them.
14. Trophic level: They are producers, take sun’s energy and inorganic matter, incorporate them into the food chain.
16. 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.

19. Can leave plants and animals submerged in water, thus altering their food chains.

1. They are consumers, eat plants, leaves, flowers, fruit, pollen, nectar, seeds and roots.
2. Trophic level: Organisms that feed on producers, in other words, herbivores and omnivores. These animals are called primary consumers.
3. factors: Are not alive.
4. They eat both vegetables and animals.
6. eruptions: Expel ash; rocks and lava and gravely damage many animals and plants that are part of a food chain.
7. It's the interaction of living things but different species in an environment.
10. Is a group of individuals of the same species.
11. Consume waste and dead animals.
15. They are consumers, eat another animals
17. 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.
