Food Chain and Food Web Worksheet for Learning About Ecosystems

Of course! Let's solve the problems in the image step by step.

## 🐠 FOOD CHAIN 1: Marine Ecosystem

Animals/Pictures:
- Seal
- Fish (blue)
- Seaweed/Algae (producer)
- Shark

Goal: Arrange them in the correct order of energy flow — from producer to top predator.

✔ Correct Order:

Seaweed → Fish → Seal → Shark

🔍 Explanation:

1. Seaweed is a producer — it makes its own food through photosynthesis.
2. Fish eats seaweed → primary consumer.
3. Seal eats fish → secondary consumer.
4. Shark eats seal → tertiary consumer / apex predator.

> So, fill the boxes left to right with:
> 1. Seaweed
> 2. Fish
> 3. Seal
> 4. Shark

## 🐔 FOOD CHAIN 2: Land Ecosystem

Animals/Pictures:
- Chicken
- Worm
- Eagle
- Leaf (represents plant/producer)

Goal: Arrange them in the correct food chain order.

✔ Correct Order:

Leaf → Worm → Chicken → Eagle

🔍 Explanation:

1. Leaf represents a plant/producer — it makes its own food.
2. Worm eats decaying leaves or organic matter → primary consumer.
3. Chicken eats worms → secondary consumer.
4. Eagle eats chickens → tertiary consumer / apex predator.

> So, fill the boxes left to right with:
> 1. Leaf
> 2. Worm
> 3. Chicken
> 4. Eagle

## 🕸️ FOOD WEB Questions

Look at the food web diagram showing:

- Producers: Wildflowers, Grass
- Consumers: Rabbit, Mouse, Snake, Hawk

Arrows show who eats whom.

---

Question 1: Select the living things that are producers

✔ Correct Answers: grass, wildflowers

> Producers make their own food (usually plants). In this web, only grass and wildflowers are producers.

---

Question 2: Select the living things that are consumers

✔ Correct Answers: hawk, mouse, rabbit, snake

> Consumers eat other organisms. All animals listed here are consumers:
> - Rabbit & Mouse → herbivores (eat plants)
> - Snake → carnivore (eats mouse/rabbit)
> - Hawk → top predator (eats snake, mouse, rabbit)

---

Question 3: Which living things do the snake eat?

✔ Answer: mouse, rabbit

> Look at the arrows pointing TO the snake — they come from the mouse and the rabbit. So the snake eats both.

---

Question 4: What is eaten by the rabbit?

✔ Answer: grass, wildflowers

> Look at the arrows pointing FROM the rabbit — they go to the rabbit from grass and wildflowers. That means the rabbit eats grass and wildflowers.

---

## ✔ Final Answers Summary:

FOOD CHAINS:

1. Seaweed → Fish → Seal → Shark
2. Leaf → Worm → Chicken → Eagle

FOOD WEB:

1. Producers: grass, wildflowers
2. Consumers: hawk, mouse, rabbit, snake
3. Snake eats: mouse, rabbit
4. Rabbit eats: grass, wildflowers
