4. Column 1, #1 How does a plant begin? As a seed.

5. Column 1, #2 What is the process in which plants reproduce? Germination.

6. Column 1, #3 Water, carbon dioxide, and sunlight. What 3 things does a plant need in order to grow?

7. Column 1, #4 Time, dehydration, lack of sunlight What are 3 causes for a plant to die?

8. Column 1, #5 Appearance What plant change takes place over time?

9. Column 2, #1 Inherited traits are something you are born with, came from your parents. What are inherited traits, also known as instincts?

10. Column 2, #2 Learned behaviors are something you learn, the way you act. What are learned behaviors?

11. Column 2, #3 Hair color is an inherited trait. Reading a book is a learned behavior. Is hair color a learned behavior or inherited trait? Is reading a book a learned behavior or inherited trait?

12. Column 2, #4 An ecosystem is all the living and nonliving things in an environment and how they interact. A habitat is a place where an animal or plant lives. What is an ecosystem? What is a habitat?

13. Column 2, #5 What can happen to an animal or plant if its ecosystem is changed? It can either adapt (change so it can survive) or die off.

14. Column 3, #1 What is photosynthesis? A process in which plants change light energy from the sun and use it to make sugar (food).

15. Column 3, #2 Where does photosynthesis occur? It occurs inside the plant cells where the chlorophyll is found.

16. Column 3, #3 What is chlorophyll? A green substance inside plant cells that traps energy from the sun.

17. Column 3, #4 Plants need carbon dioxide for photosynthesis & they give off oxygen. What type of gas do plants need for photosynthesis to take place & what type of gas do they give off?

18. Column 3, #5 Water, sunlight, and air What do plants need for photosynthesis to take place

19. Column 4, #1 What is the difference between predator and prey? Predators are animals that hunt and kill other animals for food. Prey are the animals that predators hunt.

20. Column 4, #2 A living thing (consumer) that eats meat What is a carnivore?

21. Column 4, #3 Omnivores are consumers that eat both plants and other consumers. What do omnivores eat?

22. Column 4, #4 Herbivores are living things (consumers) that eat plants. What are herbivores?

23. Column 4, #5 What is a rabbit and what is a human – carnivore, herbivore, or omnivore? A rabbit is an herbivore and humans are omnivores.

24. Column 5, #1 What do you call it when a weatherman predicts what weather will come? Weather forecasting

25. Column 5, #2 What weather measurement is used when you measure the amount of air that is pressing on anything, also known as air pressure? Barometer

26. Column 5, #3 The amount of water vapor in the air. What is humidity?

27. Column 5, #4 How is humidity measured? It is the percentage (%) of the water vapor the air can hold at a given temperature.

28. Column 5, #5 How is wind speed measured? In miles per hour.
