FOOD WEB FOOD CHAIN The diagram of a food web | StudyX - Free Printable

Let's solve each question based on the food web diagram provided.

---

1. State the main difference between a food chain and a food web.

Answer:
A food chain shows a single, linear pathway of energy transfer from one organism to another (e.g., Grass → Grasshopper → Bird → Fox).
A food web, on the other hand, shows multiple interconnected food chains, illustrating the complex feeding relationships in an ecosystem. It reflects that most organisms have more than one food source and can be part of several chains.

✔ Main Difference: A food chain is a simple, straight-line sequence, while a food web is a network of overlapping food chains showing multiple feeding relationships.

2. In the food chain: Grasses → Grasshoppers → Birds → Foxes

a) Name the producer:
➡️ Grasses
*(Producers are organisms that make their own food via photosynthesis.)*

b) Name the primary consumer:
➡️ Grasshoppers
*(Primary consumers eat producers.)*

c) Name the secondary consumer:
➡️ Birds
*(Secondary consumers eat primary consumers.)*

d) Name the tertiary consumer:
➡️ Foxes
*(Tertiary consumers eat secondary consumers.)*

3. Name an apex predator in the food chain.

Answer:
An apex predator is at the top of the food chain with no natural predators.

From the diagram:
- Foxes and Owls both appear at the top, as they are not eaten by any other animals shown.
- So, possible apex predators: Foxes or Owls

✔ Answer: Foxes or Owls *(either is acceptable)*

---

4. Name three herbivores in the food web.

Herbivores are animals that eat plants (producers).

From the diagram:
- Rabbits → eat carrots and grasses
- Mice → eat grasses and grains
- Grasshoppers → eat grasses
- Birds → eat grains (some birds are herbivorous)

✔ Three herbivores:
→ Rabbits
→ Mice
→ Grasshoppers

(Other valid answers: Birds, if considered herbivores in this context)

---

5. Name three carnivores in the food web.

Carnivores are animals that eat other animals.

From the diagram:
- Foxes → eat rabbits and mice
- Owls → eat mice and birds
- Birds → eat grasshoppers (in some cases)
- But note: Some birds may be omnivores, but here they're shown eating insects.

So, clear carnivores:
- Foxes
- Owls
- Birds (if eating grasshoppers)

✔ Three carnivores:
→ Foxes
→ Owls
→ Birds

(Alternatively: Mice could be omnivores, but not primarily carnivores; so stick with the top-level meat-eaters.)

---

✔ Final Answers Summary:

1. Difference: A food chain shows a single path of energy flow, while a food web shows multiple interconnected food chains, reflecting complex feeding relationships.

2.
a) Producer: Grasses
b) Primary consumer: Grasshoppers
c) Secondary consumer: Birds
d) Tertiary consumer: Foxes

3. Apex predator: Foxes or Owls

4. Three herbivores: Rabbits, Mice, Grasshoppers

5. Three carnivores: Foxes, Owls, Birds
