  1. Plants Produce Food

  2. Every organism on Earth needs energy to live and grow.

  3. The primary source of all life energy on Earth’s is the Sun.

  4. But animals can’t eat sunlight.

  5. Animals can only get energy by eating(consuming) other organisms (plants or animals).

  6. Animals are consumers.

  7. Animals are consumers.

  8. Animals are consumers.

  9. Animals must eat (consume) to get the energy they need.

  10. Animals must eat (consume) to get the energy they need.

  11. Animals are consumers.

  12. Animals must eat food (consume) to get the energy to live.

  13. Only green plants can producefood. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

  14. Plants make food from sunlight. Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

  15. Plants are producers. But there is one type of organism that can produce food from sunlight energy. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

  16. Plants are producers. Produce means “to make.” But there is one type of organism that can produce food from sunlight energy. Plants Plants are producers. Produce means “to make.” Producers make food from sunlight energy.

  17. Producers make food from sunlight energy.

  18. Plants are producers. They make food.Only plants can make food.

  19. Plants make food in their leaves.

  20. A green material in leaves called chlorophyll(klor oh fil) turns light energy from the sun into chemical energy (sugar).

  21. Producers convert sunlight energy into a chemical energy (glucose; sugar; food) that animals must have to live.

  22. Sugar made in the leaves moves through tubes to other parts of the plant..

  23. Plants store the food they make in different ways.

  24. Plants store the food they make in different ways.

  25. Plants store the food they make in different ways.

  26. Plant leaves must have three things in order to make food.

  27. Plants must have three things in order to make food. light

  28. water Plants must have in order to make food.

  29. carbon dioxide Plants must have in order to make food.

  30. CO2(carbon dioxide) is a gas that makes up about 1% of Earth’s atmosphere.

  31. Plants must have three things in order to make food. light wateralso calledH2O Carbon dioxide a.k.a. CO2

  32. Plants must have three things in order to make food. light wateralso calledH2O Carbon dioxide CO2

  33. Plants must have three things in order to make food. light CO2 Carbon dioxide H2O water

  34. sun Plants get the light they need from the Sun.

  35. Plants get the CO2,carbon dioxide, they need from the air.

  36. Plants get the water they need from soil with their roots.

  37. Water goes through tubes in the stem to get to the leaves.

  38. The process of plants turning sunlight energy, CO2, and water into chemical energy (food, sugar) is called …

  39. photosynthesis (foh toh SIN theh sis)

  40. The process of plants turning sunlight energy, CO2, and water into chemical energy (food, sugar) is called photosynthesis (foh toh sin theh sis)

  41. photosynthesis Photo means “light”

  42. photosynthesis Photo means “light” synthesis mean “to put together”

  43. photosynthesis Photo means “light.” Synthesis mean “to put together.” Photosynthesis mean “to put it together using light.”

  44. photosynthesis Photo means “light” synthesis mean “to put together” Photosynthesis mean “to put together with light.” Plants “put food together” using light energy in the process called photosynthesis.

  45. Plants take (CO2) carbon dioxide into their leaves and use it during photosynthesis. CO2

  46. Plants release (throw away) oxygenas a waste product as they make food. oxygen

  47. Plants release (throw away) oxygen as a waste product as they make food. Oxygen is a gas that makes up 21% of the air.

  48. Plants can’t live without CO2 and must release oxygen.

  49. Animals can’t live without oxygen and must release CO2.

  50. This is a very important balance for life on Earth.
