44 What is a renewable resource?

45 Resources that will not disappear as we use them

46 What is an example renewable resource?

47 1. Wind 2. Solar Energy 3. Hydro Energy

48 What is a nonrenewable resource?

49 Resources that cannot replace themselves once they are gone

50 What is an example of a nonrenewable resource?

51 1. Oil/Petroleum (gas, diesel, propane) 2. Natural Gas 3. Coal 4. Uranium

52 Why do we need to conserve our natural resources?

53 We protect animals and their habitats We provide a future for generations of people to come

54 Why does it mean to reduce something?

55 To make something smaller or use less of resulting in a smaller amount of waster

56 Why does it mean to reuse something?

57 We can reuse materials in original form instead of throwing them away Or Pass those materials onto someone who can use them

58 Why does it mean to recycle something?

59 Materials can be remade into the same kind of object or into something new

60 What is a habitat?

61 The natural home or environment of an animal, plant or organism

62 Why are we losing habitats?

63 1. Global warming 2. Deforestation 3. Cutting down habitats for farmland 4. Water pollution

64 Why is a food chain?

65 The order in which organisms or living things depend on one another for food

66 What is a producer?

67 Organisms that produce their own food

68 What is an example producer?

69 Plants

70 What is a consumer?
