Educational worksheet illustrating a food web with questions about producers, consumers, herbivores, and food chains.

Let's solve each question step by step using the food web shown in the worksheet.

Q1. Which of the following is a producer?

Answer:
✔ d) Plants

Explanation:
Producers are organisms that make their own food through photosynthesis (like plants). In this food web, plants are at the base and provide energy to herbivores like caterpillars and rabbits. The others (skunk, caterpillar, rabbit) are consumers.

Q2. Which of the following is an omnivore?

Answer:
✔ a) Skunk

Explanation:
An omnivore eats both plants and animals.
- Skunk eats seeds & nuts (plant-based) and also squirrels (animal-based), so it’s an omnivore.
- Caterpillar – only eats plants → herbivore.
- Rabbit – eats plants → herbivore.
- Plants – producers, not consumers.

So, skunk is the only omnivore listed.

Q3. List any three consumers from the food web.

Answer (examples):
✔ Bird, Snake, Owl

Other valid answers: Squirrel, Rabbit, Caterpillar, Skunk

Explanation:
Consumers are organisms that eat other organisms. All animals in the food web are consumers.

Q4. List any three herbivores from the food web.

Answer (examples):
✔ Rabbit, Caterpillar, Squirrel

Explanation:
Herbivores eat only plants:
- Rabbit → eats plants
- Caterpillar → eats plants
- Squirrel → eats seeds & nuts (plant parts)

Note: Skunk is an omnivore, not strictly a herbivore.

Q5. What is the food source of the caterpillar?

Answer:
✔ Plants

Explanation:
The arrow points from plants to caterpillar, meaning caterpillars eat plants.

---

Q6. Name the apex predator in the food web.

Answer:
✔ Owl

Explanation:
An apex predator is at the top of the food chain and has no natural predators.
In this web, owl eats skunk, bird, and snake — and nothing eats the owl. So, owl is the apex predator.

---

Q7. Which of the following is a food chain in the food web?

Let’s evaluate each option:

#### a) Plants → Bird → Snake → Owl
- Plants → Bird ✔ (bird eats caterpillar? Wait — bird eats caterpillar, not directly plants)
- But bird does not eat plants — it eats caterpillars. So this chain is invalid.

#### b) Plants → Rabbit → Snake → Owl
- Plants → Rabbit ✔ (rabbit eats plants)
- Rabbit → Snake ✔ (snake eats rabbit)
- Snake → Owl ✔ (owl eats snake)
→ This chain is valid ✔

#### c) Plants → Caterpillar → Skunk → Owl
- Plants → Caterpillar ✔
- Caterpillar → Skunk ✘ (skunk doesn't eat caterpillars — it eats squirrel or seeds)
- No arrow from caterpillar to skunk → invalid

#### d) Plants → Caterpillar → Squirrel → Owl
- Plants → Caterpillar ✔
- Caterpillar → Squirrel ✘ (no arrow; squirrel eats seeds/nuts, not caterpillars)
→ Invalid

✔ Only option b) is correct.

Answer:
✔ b) Plants → Rabbit → Snake → Owl
