Educational worksheet on food chains with illustrations and questions.

Let’s go step by step to answer each question based on the food chain shown.

First, look at the arrows in the diagram. Arrows show who eats whom — they point from the organism being eaten to the one that eats it.

The organisms shown are:
- Grass (producer)
- Grasshopper (eats grass)
- Mouse (eats grasshopper and maybe grass? But arrow shows mouse eats grasshopper)
- Snake (eats mouse)
- Hawk (eats snake and also has an arrow pointing from mouse → hawk? Wait — let’s check carefully.)

Actually, looking again:

Arrows:
- Grass → Grasshopper
- Grass → Mouse? No — wait, there’s an arrow from Grass to Mouse? Let me re-express what’s drawn.

From the image description (since we can’t see it but have text clues):

It says “Food Chain” with images of:
- Hawk
- Snake
- Mouse
- Grasshopper
- Grass

And arrows likely go:
Grass → Grasshopper
Grasshopper → Mouse
Mouse → Snake
Snake → Hawk

Also possibly: Mouse → Hawk? Or maybe not — depends on diagram.

But since this is a standard simple food chain, and questions refer to “the food chain”, we assume linear unless stated otherwise.

Now let’s answer each question:

1. What is the producer in this food chain?

Producers make their own food — usually plants. Here, grass is the only plant. So answer: Grass

2. There are how many consumers in this food chain?

Consumers eat other organisms. That includes:
- Grasshopper (eats grass) → primary consumer
- Mouse (eats grasshopper) → secondary consumer
- Snake (eats mouse) → tertiary consumer
- Hawk (eats snake) → quaternary consumer

That’s 4 consumers.

Wait — if hawk also eats mouse directly? Then still same number of consumer *organisms*, just more connections. But question asks “how many consumers” — meaning how many different animals that consume others.

So: Grasshopper, Mouse, Snake, Hawk → 4 consumers.

Answer: 4

3. The grasshopper is a ________.

Since it eats the producer (grass), it’s a primary consumer.

Sometimes called herbivore too — but in ecology terms for food chains, “primary consumer” is precise.

Answer: primary consumer

4. The snake is a _________.

Snake eats mouse. Mouse is a secondary consumer (because it eats primary consumer). So snake is eating a secondary consumer → makes snake a tertiary consumer.

Answer: tertiary consumer

5. Which organism gets energy from the sun?

Only producers get energy directly from the sun via photosynthesis. That’s grass.

Answer: Grass

6. The hawk is a ___________.

Hawk eats snake (which is tertiary consumer) → so hawk is quaternary consumer.

If hawk also ate mouse directly, it could be both tertiary and quaternary — but typically in such diagrams, we assign highest level.

In most school-level answers, they’d say top predator or quaternary consumer.

But let’s check common curriculum: Often, they call the top animal “top carnivore” or “apex predator”.

Looking at question wording — blank expects a term like “primary consumer”, etc.

So: Hawk eats snake → snake is tertiary → hawk is quaternary.

Answer: quaternary consumer

7. Are there decomposers in this food chain?

Decomposers break down dead things — like fungi, bacteria. They’re not shown in this diagram. The diagram only shows living feeding relationships.

So no decomposers pictured.

Answer: No

Final Answer:

1. Grass
2. 4
3. primary consumer
4. tertiary consumer
5. Grass
6. quaternary consumer
7. No
