2. What is a consumer? What are the three types of consumers?

3. A consumer is a living thing that cannot make its own food and must feed upon, or consume, living things. The three types of consumers are herbivores, carnivores, and omnivores.

4. What is a herbivore? (Provide two examples)

5. Herbivores are living things that eat only plants. Horses, zebras, beavers, elephants, parrots, tortoises, and grasshoppers are herbivores.

6. What is a carnivore? (Provide two examples)

7. Carnivores are animals that eat other animals. Polar bears, cats, sea lions, walruses, hyenas, and hawks are carnivores. Carnivores are animals that eat other animals. Polar bears, cats, sea lions, walruses, hyenas, and hawks are carnivores.

8. What is an omnivore? (Provide two examples)

9. What is a omnivore? (Provide two examples) An omnivore is a living thing that eats both plants and animals. Robins, flamingos, raccoons, blue crabs, and foxes are omnivores. An omnivore is a living thing that eats both plants and animals. Robins, flamingos, raccoons, blue crabs, and foxes are omnivores.

10. How are producers and consumers different? Which has the greater biomass?

11. Producers make their own source of energy, while consumers rely on their consumption of other organisms for energy. Producers have a greater biomass than consumers. Producers make their own source of energy, while consumers rely on their consumption of other organisms for energy. Producers have a greater biomass than consumers.

12. What is a producer? (Provide two examples)

13. Producers are living things that make their own food. Grass, trees, flowers, fruits, and vegetables are producers. Producers are living things that make their own food. Grass, trees, flowers, fruits, and vegetables are producers.

14. What is the scientific name for a living thing?

15. An organism is a living thing. An organism is a living thing.

16. What is the vocabulary word that means all of the living things in an ecosystem? What is biomass ALWAYS measured in?

17. Biomass is all of the living things in an ecosystem. Biomass is always measures in kilograms. Biomass is all of the living things in an ecosystem. Biomass is always measures in kilograms.

18. Which type of organism has the greatest biomass? (Producers, Herbivores, Carnivores, or Omnivores)

19. Producers have the highest biomass. They are always at the bottom of the food chain. Producers have the highest biomass. They are always at the bottom of the food chain.

20. What is an ecosystem? (Provide two examples)

21. An ecosystem is a community of living things and its non-living environment. Some examples of ecosystems are An ecosystem is a community of living things and its non-living environment. Some examples of ecosystems are forest, desert, ocean, Arctic, coral reef, grassland, tropical rainforest.

22. What is the environment? (Provide two examples of things that make up the environment)

23. The environment is all of the living and non living things that make up one’s surroundings. Some aspects of the environment are w The environment is all of the living and non living things that make up one’s surroundings. Some aspects of the environment are weather, climate, soil, rocks, humidity, and rainfall.

24. What is a food chain?

25. A food chain is a straight-line diagram that shows which living things are eaten by others.

26. What is a food web?

27. A food web is a diagram that combines different food chains to show all of the foods that living things eat.

28. Describe one way that humans should protect organisms and their environments/ ecosystems. We need to be careful of how much of the resources we are taking (Are we overfishing and taking another animal’s food source?) We need to be careful of how we treat the environment (Are we destroying animals’ homes and affecting their ability to find food? (Through global warming, building and developing on the land, etc.)) We need to be careful of how we dispose of our waste (Is our garbage causing harm to other animals and negatively impacting the food chain?
