Food Chains and Webs

1. Food Chains and Webs Study Guide

2. Carnivore: • Animal that eats only other animals

3. Prey • Animal that is killed and eaten by another animal

4. Decomposer • Organism that feeds on and breaks down dead organisms

5. Ecosystem • All the interacting living and nonliving things in an area

6. Nutrients • Things in food that living things need

7. Herbivore • Animal that eats only plants

8. Food Chain • Shows how living things get food and energy

9. Habitat • Place where an organism lives

10. Producer • Green plant that makes food

11. Species • Group of living things that are all the same kind

12. Adaptations • A behavior or body part that helps an organism survive in its habitat

13. Ecology • The study of living and nonliving things and their interactions

14. Community • All the populations of animals that live in an area

15. Endangered • An animal species in which very few of its kind are left

16. Predator • An animal that hunts and eats other animals

17. Primary Consumer • An animal that gets its energy only from producers

18. Variations • Differences among animals of the same kind

19. Order of Food Chain with Examples Producer ->Primary Consumer->Secondary Consumer->Tertiary Consumer i.e. grass -> crickets -> anole -> Owl Decomposer i.e. earthworm and fungi

20. Examples of Adaptation • Camouflage • Mimicry • Body parts (like the anole’s toes and tail)

21. Why might animals need to adapt its behavior? • It needs protection like trying to hide when it’s getting hunted • It needs to move like using antennae or bristles • Its habitat changed like leaving a place when there’s no food left

22. What happens as an energy pyramid goes from bottom to top? • It gets smaller because the energy is used up at each level going from the bottom to the top

23. Which role in the food chain puts nutrients back into the soil for plants? • decomposers

24. Producers give their energy to • Primary consumers, or herbivores

25. Why are plants so important in a food chain? • They’re important because all animals eat plants or other animals that eat plants
