00:00:01.860 --> 00:00:04.860
laughs

3
00:00:05.339 --> 00:00:07.259
food chain

4
00:00:07.259 --> 00:00:10.200
the food you eat gives you energy the

5
00:00:10.200 --> 00:00:12.480
path that energy takes as it moves from

6
00:00:12.480 --> 00:00:15.719
the Sun to the Earth to plants to

7
00:00:15.719 --> 00:00:18.420
animals and back to the Earth again is

8
00:00:18.420 --> 00:00:20.220
called the food chain

9
00:00:20.220 --> 00:00:22.500
you were just one stop on that food

10
00:00:22.500 --> 00:00:23.960
chain

11
00:00:23.960 --> 00:00:26.460
photosynthesis is the first step in the

12
00:00:26.460 --> 00:00:29.939
food chain it starts with producers a

13
00:00:29.939 --> 00:00:32.640
producer is an organism like a plant

14
00:00:32.640 --> 00:00:35.100
that captures energy from the Sun to

15
00:00:35.100 --> 00:00:37.200
help it make its own food

16
00:00:37.200 --> 00:00:40.100
this process is called photosynthesis

17
00:00:40.100 --> 00:00:43.800
the plants roots and leaves need water

18
00:00:43.800 --> 00:00:46.620
and sunlight for photosynthesis to work

19
00:00:46.620 --> 00:00:49.200
in the leaves on a plant there is

20
00:00:49.200 --> 00:00:51.960
something called chlorophyll chlorophyll

21
00:00:51.960 --> 00:00:54.539
traps light from the sun and reflects

22
00:00:54.539 --> 00:00:57.180
green light which is why most plants are

23
00:00:57.180 --> 00:00:58.020
green

24
00:00:58.020 --> 00:01:00.840
the roots of a plant then absorb the

25
00:01:00.840 --> 00:01:02.879
water from the soil around it

26
00:01:02.879 --> 00:01:05.938
the water flows into tiny tubes in the

27
00:01:05.938 --> 00:01:08.760
plant and then up the stem the tubes

28
00:01:08.760 --> 00:01:11.159
then send the water to the leaves where

29
00:01:11.159 --> 00:01:14.100
the sunlight is captured tiny holes in

30
00:01:14.100 --> 00:01:16.860
the leaves allow carbon dioxide to enter

31
00:01:16.860 --> 00:01:18.060
the plant

32
00:01:18.060 --> 00:01:21.180
carbon dioxide is a gas that is made of

33
00:01:21.180 --> 00:01:24.240
carbon and oxygen it is in the air all

34
00:01:24.240 --> 00:01:27.360
around us it is very important for

35
00:01:27.360 --> 00:01:28.560
plants

36
00:01:28.560 --> 00:01:31.259
the plant releases the oxygen out of its

37
00:01:31.259 --> 00:01:34.200
leaves the holes in the leaves open and

38
00:01:34.200 --> 00:01:37.140
close they know how much carbon dioxide

39
00:01:37.140 --> 00:01:39.600
to let in and can also stop too much

40
00:01:39.600 --> 00:01:42.060
water from escaping using the

41
00:01:42.060 --> 00:01:44.520
chlorophyll the plant then transforms

42
00:01:44.520 --> 00:01:46.700
water and carbon dioxide into

43
00:01:46.700 --> 00:01:49.680
carbohydrates or sugar which gives the

44
00:01:49.680 --> 00:01:53.040
plant energy that energy is now ready

45
00:01:53.040 --> 00:01:55.140
for the next stop on the food chain

46
00:01:55.140 --> 00:01:57.240
which is the consumer

47
00:01:57.240 --> 00:02:00.060
the consumer is the organism that eats

48
00:02:00.060 --> 00:02:00.960
the plant

49
00:02:00.960 --> 00:02:03.479
all animals including humans are

50
00:02:03.479 --> 00:02:06.960
consumers you are a consumer because you

51
00:02:06.960 --> 00:02:09.119
cannot use the sun's energy to make food

52
00:02:09.119 --> 00:02:11.940
for your own body like a plant can

53
00:02:11.940 --> 00:02:14.700
you rely on the producer or the plant to

54
00:02:14.700 --> 00:02:17.580
make that energy for you you then eat

55
00:02:17.580 --> 00:02:20.459
that plant and absorb the energy that is

56
00:02:20.459 --> 00:02:24.000
already in it a primary consumer is an

57
00:02:24.000 --> 00:02:26.220
organism that directly eats the plants

58
00:02:26.220 --> 00:02:28.319
like a cow

59
00:02:28.319 --> 00:02:31.680
a secondary consumer is an animal that

60
00:02:31.680 --> 00:02:34.319
eats the primary consumer that eat the

61
00:02:34.319 --> 00:02:37.980
plant here's an example a plant is the

62
00:02:37.980 --> 00:02:41.400
producer a cow is a primary consumer

63
00:02:41.400 --> 00:02:43.500
because it ate the plant

64
00:02:43.500 --> 00:02:46.620
you are a secondary consumer because you

65
00:02:46.620 --> 00:02:49.260
ate the cow that ate the plant

66
00:02:49.260 --> 00:02:51.660
if you eat a piece of corn on the cob

67
00:02:51.660 --> 00:02:53.940
directly then you become the primary

68
00:02:53.940 --> 00:02:56.700
consumer you are also the primary

69
00:02:56.700 --> 00:02:59.300
consumer if you eat an apple

70
00:02:59.300 --> 00:03:02.280
strawberries and other fruits as well as

71
00:03:02.280 --> 00:03:05.099
any vegetables that's because you are

72
00:03:05.099 --> 00:03:06.959
getting your energy directly from those

73
00:03:06.959 --> 00:03:08.160
plants

74
00:03:08.160 --> 00:03:10.739
if you eat a hamburger you become a

75
00:03:10.739 --> 00:03:13.739
secondary consumer because the cow which

76
00:03:13.739 --> 00:03:16.379
is the place that hamburger came from is

77
00:03:16.379 --> 00:03:19.200
the one that ate the plants first

78
00:03:19.200 --> 00:03:21.959
the hamburger also gives you energy and

79
00:03:21.959 --> 00:03:23.220
nutrients

80
00:03:23.220 --> 00:03:25.800
but you cannot eat the same nutrients

81
00:03:25.800 --> 00:03:28.739
from corn that a cow ate as you can from

82
00:03:28.739 --> 00:03:31.319
corn that you eat yourself in the food

83
00:03:31.319 --> 00:03:34.560
chain the energy in food is passed down

84
00:03:34.560 --> 00:03:36.720
from one consumer to the next

85
00:03:36.720 --> 00:03:39.420
the food gives away some of its energy

86
00:03:39.420 --> 00:03:42.659
at each stop it makes that's why it's

87
00:03:42.659 --> 00:03:44.220
important to eat your fruits and

88
00:03:44.220 --> 00:03:46.080
vegetables directly too

89
00:03:46.080 --> 00:03:48.420
there are different types of consumers

90
00:03:48.420 --> 00:03:51.120
they are grouped by the kinds of food

91
00:03:51.120 --> 00:03:52.560
that they eat

92
00:03:52.560 --> 00:03:55.319
herbivores are organisms that eat only

93
00:03:55.319 --> 00:03:59.220
plants and vegetables cows deer and

94
00:03:59.220 --> 00:04:01.099
elephants are examples

95
00:04:01.099 --> 00:04:04.319
carnivores eat other animals or only

96
00:04:04.319 --> 00:04:08.940
meat lions tigers bears

97
00:04:08.940 --> 00:04:11.760
and seals are examples

98
00:04:11.760 --> 00:04:15.320
an omnivore eats both plants and animals

99
00:04:15.320 --> 00:04:19.440
examples include humans bears and

100
00:04:19.440 --> 00:04:22.440
chickens the last step or the very

101
00:04:22.440 --> 00:04:24.600
bottom of the food chain is the

102
00:04:24.600 --> 00:04:27.320
decomposers

103
00:04:27.380 --> 00:04:29.940
decomposers break down dead matter into

104
00:04:29.940 --> 00:04:32.040
substances that can be used by The

105
00:04:32.040 --> 00:04:35.900
Producers or plants worms insects

106
00:04:35.900 --> 00:04:39.600
bacteria and fungi are examples of

107
00:04:39.600 --> 00:04:43.020
decomposers decomposed matter returns to

108
00:04:43.020 --> 00:04:45.120
the soil and becomes food for the

109
00:04:45.120 --> 00:04:48.060
producers here is an example of a basic

110
00:04:48.060 --> 00:04:51.000
food chain the plant is a producer

111
00:04:51.000 --> 00:04:53.160
because it provides its own food through

112
00:04:53.160 --> 00:04:56.279
energy from the Sun the mice are primary

113
00:04:56.279 --> 00:04:58.199
consumers because they get energy

114
00:04:58.199 --> 00:05:00.259
directly from the plant when they eat it

115
00:05:00.259 --> 00:05:03.839
the owl is a secondary consumer because

116
00:05:03.839 --> 00:05:06.060
it gets its energy from the mice when it

117
00:05:06.060 --> 00:05:09.660
eats them once the owl dies its body

118
00:05:09.660 --> 00:05:12.060
begins to decompose or go back into the

119
00:05:12.060 --> 00:05:13.100
soil

120
00:05:13.100 --> 00:05:17.160
decomposers such as worms insects and

121
00:05:17.160 --> 00:05:19.380
other organisms break down the matter

122
00:05:19.380 --> 00:05:21.900
from the owl's body and leave nutrients

123
00:05:21.900 --> 00:05:24.600
in the soil from that matter the

124
00:05:24.600 --> 00:05:26.880
nutrients in the soil then enter the

125
00:05:26.880 --> 00:05:30.120
plant and the food chain starts all over

126
00:05:30.120 --> 00:05:32.940
again the next time you decide what to

127
00:05:32.940 --> 00:05:35.160
eat think of the food chain and where

128
00:05:35.160 --> 00:05:36.720
your food came from

129
00:05:36.720 --> 00:05:39.660
see if you are the primary consumer or

130
00:05:39.660 --> 00:05:42.419
the secondary consumer how much energy

131
00:05:42.419 --> 00:05:44.520
will you get from the item you chose to

132
00:05:44.520 --> 00:05:47.639
eat remember the better the food you eat

133
00:05:47.639 --> 00:05:50.880
the better your body can perform hope
