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. (glucose; sugar; food)

in order to make food.

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

34. 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.

46. Plants release (throw away)
oxygen as 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.

51. Now, let’s see how much you remember about producers and photosynthesis.

52. Which type of organisms must eat other organisms?

53. Consumers (animals) must eat other organisms.

54. Which type of organisms can make food?
