Food Chains and Food Web
What Are Some Parts of a Food Chain and a Food Web?
2
Key Words Consumer A living thing that eats other living things
Food chain Pathway of energy through an ecosystem Food Energy Where energy gets passed from one consumer to another. Food web Interconnecting food chains in an ecosystem, which shows many energy relationships Producer Living things that make their own food by photosynthesis
3
a. List the organisms that you think are producers?
Roots, seeds, leaves, stems, and fruits
4
b. Why are they called Producers?
They make food (glucose) by photosynthesis
5
c. List the organisms that you think are primary consumers
Rabbit Mouse Earthworm Cricket Small insects
6
d. Why are they called primary consumers?
Primary consumers, which are herbivores eat producers.
7
e. List the organisms that you think are secondary consumers.
Fox Robin Snake Hawk Mouse Owl
8
f. Why are they called secondary consumers?
They eat consumers
9
g. Herbivores are organisms that eat plants
g. Herbivores are organisms that eat plants. List the herbivores in the food chains. Rabbit Mouse Earthworm Cricket Small Insects
10
h. How does your list of herbivores compare with your list in question c?
They are the same organisms
11
i. Carnivores are organisms that eat other animals
i. Carnivores are organisms that eat other animals. List the carnivores in the food chains. Fox Robin Snake Hawk Mouse owl
12
J. How does your list of carnivores compare with your list in question e?
They are the same.
13
K. Make two food chains using animals not listed in the above food chains.
spider Plant Parts millipede Plant Parts cat Squirrel

Questions on Back (254)
21
Hawk 3 Earthworm 2 Fox 5 Snake 5 Owl 3 Small Insects 2
1. How many of the food chains you made in Figure 1 include the following animals? Hawk 3 Earthworm 2 Fox 5 Snake 5 Owl 3 Small Insects 2
22
2. How many food chains include plant parts?
12 (all of them)
23
3. Give the names of the producers that are in the food web.
Plants
24
4. Give the names of the of the consumers that eat both plants and animals.
Mouse
25
5. What would happen to the food web if all the plants were removed?
Everything would die.
26
5 b. Explain your answer. Plants are involved in all of the food chains and are the base of the food chain in all ecosystems.
27
6. What might happen to the owl population is there were less rabbits, mice, and snakes in a certain year? There would be less owls because of the lack of food
28
7. What organisms will be affected if crickets, small insects, and earthworms are killed by pesticides? Robins will be most affected because these three organisms are their only food in the food web. Other organisms that eat these three organisms also feed on other organisms in the food web.
29
8. Draw three food chains below that can be connected in a food web
8. Draw three food chains below that can be connected in a food web. Show producers and consumers that you might see in your back yard or on your way to school
