Food Web interactive activity - Free Printable

Here's the complete solution to the food web worksheet, with explanations for each answer:

---

1. Select the living things from the food web that are producers:

✔ Correct Answers: grass, leaves

🔹 Explanation: Producers are organisms that make their own food, usually through photosynthesis. In this food web, grass and leaves (from plants/trees) are the only producers. They form the base of the food web and do not eat other organisms.

✘ *Rabbit, blue jay, snake* are consumers — they eat other living things.

---

2. Select the living things from the food web that are primary consumers:

✔ Correct Answers: caterpillar, rabbit, grasshopper

🔹 Explanation: Primary consumers are herbivores — animals that eat producers (plants). In this diagram:
- Caterpillar eats leaves
- Rabbit eats grass
- Grasshopper eats grass

These are all directly consuming producers, so they are primary consumers.

✘ *Hawk, snake* are higher-level consumers.

---

3. Select the living things from the food web that are secondary consumers:

✔ Correct Answers: blue jay, snake, hawk

🔹 Explanation: Secondary consumers eat primary consumers.
- Blue jay eats grasshopper (primary consumer)
- Snake eats caterpillar and rabbit (both primary consumers)
- Hawk eats rabbit and grasshopper (both primary consumers)

Note: Some animals can be in multiple levels depending on what they eat. Here, hawk and snake can also be tertiary consumers, but since the question asks for secondary consumers, we include them here because they *do* eat primary consumers.

✘ *Rabbit, owl* — rabbit is primary; owl is tertiary (eats secondary consumers).

4. Select the living things from the food web that are tertiary consumers:

✔ Correct Answers: owl, hawk, blue jay

🔹 Explanation: Tertiary consumers eat secondary consumers.
- Owl eats snake and hawk → both are secondary consumers
- Hawk eats snake → snake is a secondary consumer
- Blue jay — technically, it only eats grasshopper (primary), so it’s *not* a tertiary consumer. But if we look at the arrows, blue jay is eaten by owl, and it doesn’t eat any secondary consumers — so blue jay should NOT be selected here.

⚠️ Correction needed: Based strictly on the food web:
- Owl eats snake and hawk → both secondary → so owl is tertiary.
- Hawk eats snake → snake is secondary → so hawk is tertiary.
- Blue jay eats grasshopper → primary → so blue jay is *secondary*, not tertiary.

✔ So correct answers should be: owl, hawk

But since “blue jay” is an option and might be mistakenly included, let’s double-check the arrows:
→ Blue jay ← Grasshopper (so blue jay eats primary consumer → secondary consumer)
→ Blue jay → Owl (so blue jay is eaten by tertiary consumer)
→ Blue jay does NOT eat any secondary consumers → NOT tertiary

✔ Final Answer: owl, hawk

*(Note: The worksheet may have intended to include blue jay as tertiary, but biologically, based on this diagram, it’s not.)*

5. Which living things do the owl eat?

✔ Correct Answers: snake, hawk, blue jay

🔹 Explanation: Look at the arrows pointing TO the owl:
- Arrow from snake → owl
- Arrow from hawk → owl
- Arrow from blue jay → owl

So the owl eats snake, hawk, and blue jay.

✘ *Rabbit, caterpillar* — no direct arrow from them to owl.

---

6. What is eaten by the blue jay?

✔ Correct Answer: grasshopper

🔹 Explanation: Look at the arrow pointing TO the blue jay:
- Arrow from grasshopper → blue jay

That means the blue jay eats the grasshopper.

✘ *Snake, rabbit, owl* — these are not eaten by blue jay (arrows go the other way or don’t exist).

---

## ✔ FINAL ANSWERS SUMMARY:

1. Producers: grass, leaves
2. Primary Consumers: caterpillar, rabbit, grasshopper
3. Secondary Consumers: blue jay, snake, hawk
4. Tertiary Consumers: owl, hawk *(blue jay is incorrect here — it’s secondary)*
5. Owl eats: snake, hawk, blue jay
6. Blue jay eats: grasshopper

📌 Tip for students: Always follow the arrows! Arrows show the direction of energy flow — from who is eaten → to who eats it.
