Food Chains and Food Webs Worksheet
####
Left Side: Food Chain Questions
The food chain provided is:
Green Plants → Grasshopper → Bird → Snake → Hawk
1.
Q1. What does the arrow mean in a food chain?
-
Answer: The arrow in a food chain indicates the direction of energy flow. It shows who eats whom, with the arrow pointing from the organism that is eaten to the organism that eats it.
2.
Q2. Name the producer in the food chain.
-
Answer: The producer is the organism that makes its own food through photosynthesis. In this food chain, the
Green Plants are the producer.
3.
Q3. Name the primary consumer in the food chain.
-
Answer: The primary consumer is the organism that directly eats the producer. Here, the
Grasshopper is the primary consumer because it eats the green plants.
4.
Q4. Name the secondary consumer in the food chain.
-
Answer: The secondary consumer is the organism that eats the primary consumer. In this case, the
Bird is the secondary consumer because it eats the grasshopper.
5.
Q5. Name the tertiary consumer in the food chain.
-
Answer: The tertiary consumer is the organism that eats the secondary consumer. Here, the
Snake is the tertiary consumer because it eats the bird.
6.
Q6. Name the apex predator in the food chain.
-
Answer: The apex predator is the top predator in the food chain, which has no natural predators. In this food chain, the
Hawk is the apex predator.

Right Side: Food Web Questions
The food web provided includes the following organisms:
- Producers: Green Plants
- Consumers: Grasshopper, Frog, Mouse, Deer, Snake, Eagle
1.
Q1. Name the producer in the food web.
-
Answer: The producer in the food web is the
Green Plants, as they are the source of energy for all other organisms in the ecosystem.
2.
Q2. Name three consumers in the food web.
-
Answer: Three consumers in the food web are:
1.
Grasshopper
2.
Frog
3.
Mouse
3.
Q3. What does a frog eat?
-
Answer: According to the food web, the frog eats the
Grasshopper.
4.
Q4. Name the apex predator in the food web.
-
Answer: The apex predator is the organism at the top of the food web, which has no natural predators. In this food web, the
Eagle is the apex predator.

Explanation:
-
Producers: These are organisms that produce their own food through photosynthesis, such as green plants.
-
Primary Consumers: These are herbivores that eat producers (e.g., grasshoppers).
-
Secondary Consumers: These are carnivores or omnivores that eat primary consumers (e.g., birds).
-
Tertiary Consumers: These are carnivores that eat secondary consumers (e.g., snakes).
-
Apex Predator: This is the top predator in the food chain/web, with no natural predators (e.g., hawks or eagles).
This worksheet helps students understand the roles of different organisms in an ecosystem and how energy flows through food chains and webs.
