Food Web interactive activity - Free Printable

Let's solve this food web step by step and explain each part.

---

1. Producers

Producers are organisms that make their own food through photosynthesis (like plants).

From the food web:
- Grass → makes its own food
- Leaves → part of a plant, also produce food via photosynthesis

✔ Correct answers:
✔️ grass
✔️ leaves

> Note: "Leaves" are shown as a separate item but represent plant parts that are producers.

---

2. Primary Consumers

Primary consumers eat producers (plants). They are herbivores.

From the food web:
- Caterpillar → eats leaves
- Rabbit → eats grass
- Grasshopper → eats grass

✔ Correct answers:
✔️ caterpillar
✔️ rabbit
✔️ grasshopper

> ✘ Incorrect: hawk, snake (they are carnivores)

---

3. Secondary Consumers

Secondary consumers eat primary consumers (herbivores).

From the food web:
- Snake → eats caterpillar
- Blue jay → eats grasshopper
- Hawk → eats rabbit
- Owl → eats snake, blue jay

Wait — let’s analyze carefully:

- Snake → eats caterpillar (primary consumer) → ✔ secondary consumer
- Blue jay → eats grasshopper (primary consumer) → ✔ secondary consumer
- Hawk → eats rabbit (primary consumer) → ✔ secondary consumer
- Owl → eats snake and blue jay → these are secondary consumers → so owl is tertiary, not secondary

So:
✔ Secondary consumers:
✔️ snake
✔️ blue jay
✔️ hawk

> ✘ Rabbit – it’s a primary consumer
> ✘ Owl – it's a tertiary consumer

---

4. Tertiary Consumers

Tertiary consumers eat secondary consumers.

From the food web:
- Owl → eats snake and blue jay (both secondary consumers)
- Hawk → eats rabbit only → rabbit is primary consumer → so hawk is secondary
- Snake → eats caterpillar → primary consumer → secondary
- Blue jay → eats grasshopper → primary → secondary

Only owl eats secondary consumers (snake and blue jay)

✔ Tertiary consumer:
✔️ owl

> ✘ Others: caterpillar (producer eater), blue jay (secondary), hawk (secondary), grasshopper (primary)

---

5. Which living things do the owl eat?

Look at arrows pointing to the owl:
- Arrow from snake
- Arrow from blue jay

✔ So, owl eats:
✔️ snake
✔️ blue jay

> ✘ rabbit, caterpillar, owl (doesn't eat itself)

---

6. What is eaten by the blue jay?

Look at arrows pointing from the blue jay or to it?

Wait: The arrow shows grasshopper → blue jay, meaning blue jay eats grasshopper

✔ So, grasshopper is eaten by the blue jay.

> ✘ snake, rabbit, owl — no arrows show those being eaten by blue jay

---

✔ Final Answers:

#### 1. Producers:
✔️ grass
✔️ leaves

#### 2. Primary consumers:
✔️ caterpillar
✔️ rabbit
✔️ grasshopper

#### 3. Secondary consumers:
✔️ snake
✔️ blue jay
✔️ hawk

#### 4. Tertiary consumers:
✔️ owl

#### 5. Which living things do the owl eat?
✔️ snake
✔️ blue jay

#### 6. What is eaten by the blue jay?
✔️ grasshopper

📝 Summary Explanation:

- Producers = make their own food → plants (grass, leaves)
- Primary consumers = eat plants → herbivores (caterpillar, rabbit, grasshopper)
- Secondary consumers = eat herbivores → carnivores or omnivores (snake, blue jay, hawk)
- Tertiary consumers = eat secondary consumers → top predators (owl)
- Arrows show who eats whom → arrow points to the predator

This food web shows multiple feeding paths and energy flow from producers to top predators.
