Let’s go step by step to solve this worksheet.

Part 1: Matching Column A to Column B
We need to match each sentence in Column A (numbered 1–7) with the correct life process from Column B (lettered A–G).
Let’s look at each one:
1. Humans and animals eat plants for energy.
→ This is about taking in food → D. FEEDING
2. Plants take in carbon dioxide from the atmosphere and release oxygen.
→ This is gas exchange — breathing! Even though it’s not lungs, plants “breathe” too → F. BREATHING
3. Plants get rid of waste through the process of transpiration.
→ Getting rid of waste = excreting → E. EXCRETING
4. Plants turn towards the sunlight or water.
→ They are reacting to their environment — sensing light/water → G. SENSING
5. Some animals hibernate in the winter.
→ Hibernation involves slowing down movement and activity — but actually, hibernation is more about surviving cold by reducing metabolism. However, among the options, “MOVING” doesn’t fit well… Wait — let’s think again. Actually, hibernation isn’t directly listed. But looking back — maybe we missed something? Let’s check all matches first.
Wait — perhaps #5 is tricky. Let’s hold on and do the rest.
6. Humans and animals have offspring (babies)
→ Making babies = reproducing → A. REPRODUCING
7. A seedling grows into a plant.
→ Getting bigger = growing → C. GROWING
Now back to #5: Some animals hibernate in the winter.
Hibernation is a state where animals slow down — they don’t move much. So it relates to B. MOVING? Not exactly — because they’re *not* moving. Hmm.
Actually, hibernation is often grouped under survival behaviors, but since “MOVING” is the only option left that might relate (even if indirectly), and all others are taken... let’s see what’s unmatched.
Used so far:
- 1 → D
- 2 → F
- 3 → E
- 4 → G
- 6 → A
- 7 → C
Left: #5 and B (MOVING)
But hibernation ≠ moving. That doesn’t make sense.
Wait — maybe I made a mistake earlier.
Let me double-check #2: “Plants take in carbon dioxide... and release oxygen.” Is that really “breathing”? In biology, plants do respire (take in O₂, release CO₂) during day/night, but photosynthesis takes in CO₂ and releases O₂. The question says “take in carbon dioxide... and release oxygen” — that’s photosynthesis, which is part of feeding/growing? But “FEEDING” is already used for eating.
Actually, in many school curricula, “breathing” for plants refers to respiration, not photosynthesis. But the description here sounds like photosynthesis.
This is confusing. Let’s reconsider based on standard 7 life processes taught in schools:
The 7 life processes are often remembered as MRS GREN:
- Movement
- Respiration (Breathing)
- Sensitivity (Sensing)
- Growth
- Reproduction
- Excretion
- Nutrition (Feeding)
So:
#2: Taking in CO₂ and releasing O₂ — that’s photosynthesis, which falls under Nutrition (Feeding)? But #1 is also feeding.
Wait — no. Photosynthesis is how plants make food — so it’s part of feeding/nutrition. But #1 is about animals eating plants — also feeding.
That would mean two items for feeding? No, probably not.
Alternative interpretation:
Maybe #2 is meant to be “respiration” — but plants respire by taking in O₂ and releasing CO₂, opposite of what’s written.
The statement says: “take in carbon dioxide... and release oxygen” — that’s definitely photosynthesis.
In some contexts, especially lower grades, they simplify and call photosynthesis part of “breathing” for plants — even though scientifically inaccurate. Given the options, and since “feeding” is taken by #1, perhaps #2 is intended to be “breathing”.
Alternatively, maybe #1 is “feeding”, #2 is “breathing” (as in gas exchange, even if misstated).
Given common textbook simplifications, I’ll go with:
#2 → F. BREATHING (assuming they mean gas exchange related to respiration/photosynthesis combo)
Then #5: Hibernation — animals reduce movement, so it’s still under “movement” category? Or maybe it’s not covered? But we must assign.
Actually, hibernation is a behavioral adaptation involving reduced movement — so perhaps it fits under B. MOVING as an example of controlling movement.
Yes — that makes sense in elementary science. Animals can choose to stop moving (hibernate) — so it’s part of the “moving” life process.
So:
#5 → B. MOVING
Perfect — now all matched:
1 → D
2 → F
3 → E
4 → G
5 → B
6 → A
7 → C

Part 2: Identify life process from pictures
There are 6 images:
Top row, left to right:
1. Lungs → clearly BREATHING
2. Seed sprouting → GROWING
3. Lion sleeping/hiding? Looks like it’s resting or hiding — could be MOVING (if it moved there) or maybe SENSING? Wait — lion curled up — perhaps REPRODUCING? No. Maybe EXCRETING? Unlikely.
Actually, looking closely — it looks like a lion lying down, possibly after hunting or resting. Could be MOVING (it moved to rest) or maybe FEEDING if it just ate? But no food shown.
Wait — another possibility: in some worksheets, a sleeping animal represents MOVING (since movement includes stopping/resting). Or perhaps it’s SENSING — being alert? Doesn’t look alert.
Actually, let’s look at bottom row first.
Bottom row, left to right:
4. Person eating → FEEDING
5. Tree losing leaves → EXCRETING (plants excrete via leaf drop)
6. Person running → MOVING
Back to top row middle-right: lion — if it’s sleeping, maybe it’s REPRODUCING? No. Perhaps it’s GROWING? No.
Wait — maybe the lion image is meant to show REPRODUCING if it’s with cubs? But it looks alone.
Another thought: in some versions, a sleeping animal is associated with MOVING because movement includes changing position or resting.
But let’s think differently — perhaps the lion is showing SENSING — ears up, listening? Hard to tell.
Actually, looking again — the third image (top right) appears to be a lion cub with its mother? Or maybe just a lion sitting. If it’s a mother with cub, then REPRODUCING.
But in black-and-white sketch, it’s ambiguous.
Wait — let’s list knowns:
Image 1: Lungs → BREATHING
Image 4: Eating person → FEEDING
Image 5: Tree shedding leaves → EXCRETING
Image 6: Running person → MOVING
Left: Image 2 (seedling) → GROWING
Image 3 (lion) → must be REPRODUCING or SENSING
If image 2 is growing, then image 3 should be REPRODUCING — assuming the lion has cubs or is mating.
In many such worksheets, a lion with cubs = reproducing.
I think we’ll assume image 3 is REPRODUCING
And image 2 is GROWING
So final assignments:
Top row:
1. Lungs → BREATHING
2. Seedling → GROWING
3. Lion (with cubs?) → REPRODUCING
Bottom row:
4. Eating → FEEDING
5. Tree dropping leaves → EXCRETING
6. Running → MOVING
What about SENSING? We haven’t used it yet. Did we miss an image?
Count: 6 images, 7 processes — one process won’t be used in the picture section. That’s fine.
In our matching, we had:
Matching answers:
1-D, 2-F, 3-E, 4-G, 5-B, 6-A, 7-C
For pictures:
Lungs → F (Breathing)
Seedling → C (Growing)
Lion → A (Reproducing)
Eating → D (Feeding)
Tree → E (Excreting)
Running → B (Moving)
SENSING (G) is not used in pictures — which is okay, since there are 7 processes and only 6 pictures.
Perfect.
