Let’s solve this step by step.

We are given a word box with these words:
- other
- different
- protect
- breathe
- sun
- animals
- dangerous
- need
- weather
- food
- energy
- life
- get
- shelter
- care

We must use each word once to fill in the blanks in the paragraph.

Here is the paragraph with blanks:

> All living things ______ one another. The plants produce oxygen, which animals need to ______. The ______ produce carbon dioxide, which the plants need to breathe. Plants are also ______ to many animals. The plants get ______ from the ______, and the animals that eat the plants ______ that energy. Some animals are food to ______ animals. This is necessary for ______ to exist. Plants can also provide ______ to animals. This helps animals ______ themselves from bad ______, or from other ______ animals. If we do not take ______ of the living things in our environment, life would be very ______.

---

Let’s go blank by blank and pick the best fitting word from the box.

1. “All living things ______ one another.”
→ Makes sense: “depend on” isn’t there, but “need” fits well.
✔ need

2. “...which animals need to ______.”
→ Animals need oxygen to breathe.
✔ breathe

3. “The ______ produce carbon dioxide...”
→ Who produces CO₂? Animals (and humans).
✔ animals

4. “Plants are also ______ to many animals.”
→ Plants are useful → “important”? Not in list. “Different”? No. “Food”? Maybe later. Wait — “shelter”? Or “care”? Hmm. Let’s think: plants give food, shelter, etc. But next sentence talks about energy from sun. So maybe here it’s “food”? But let’s hold. Actually, look ahead: “Plants can also provide ______ to animals” — that might be shelter. So perhaps here it’s “food”? But wait — “Plants are also ______ to many animals.” Could be “important”, but not in list. Another idea: “different”? Doesn’t fit. “Dangerous”? No. “Other”? No. Wait — maybe “life”? “Plants are also life to many animals”? That sounds odd. Let’s skip and come back.

Actually, re-read: “Plants are also ______ to many animals.” Perhaps “food”? But then later it says “Some animals are food to ______ animals.” So “food” might be used twice? No — we can only use each word once.

Wait — maybe “shelter”? But again, later it says “provide ______ to animals” — likely shelter.

Another thought: “Plants are also important” — not in list. What about “necessary”? Not in list. Let’s look at remaining words after filling obvious ones.

Maybe try this approach: fill the easiest first.

Blank 5: “The plants get ______ from the ______”

→ Plants get energy from the sun. Classic science fact.

✔ Blank 5: energy
✔ Blank 6: sun

Blank 7: “...animals that eat the plants ______ that energy.”

→ They get that energy.

✔ get

Blank 8: “Some animals are food to ______ animals.”

→ Predators eat prey → so “other” animals? Or “different”? “Other” makes more sense.

✔ other

Blank 9: “This is necessary for ______ to exist.”

→ For life to exist.

✔ life

Blank 10: “Plants can also provide ______ to animals.”

→ Shelter? Food? We haven’t used “shelter” yet. And earlier we had “Plants are also ______ to many animals.” Maybe that was “food”? Let’s assign:

If blank 10 is “shelter”, then blank 4 could be “food”.

Try:

Blank 4: “Plants are also food to many animals.” → Yes, that works.

Blank 10: “provide shelter to animals.” → Also good.

✔ Blank 4: food
✔ Blank 10: shelter

Blank 11: “This helps animals ______ themselves from bad ______”

→ Protect themselves from bad weather? Or dangerous animals?

“Protect” is in the list. “Weather” is in the list. “Dangerous” is also there.

So: “helps animals protect themselves from bad weather”

Then next part: “or from other ______ animals.”

→ “dangerous” animals.

✔ Blank 11: protect
✔ Blank 12: weather
✔ Blank 13: dangerous

Blank 14: “If we do not take ______ of the living things...”

→ Take care of them.

✔ care

Blank 15: “...life would be very ______.”

→ Very different? Or “bad”? “Different” is left. “Life would be very different” — yes, that makes sense.

What’s left? Let’s check used words:

Used so far:

1. need
2. breathe
3. animals
4. food
5. energy
6. sun
7. get
8. other
9. life
10. shelter
11. protect
12. weather
13. dangerous
14. care
15. ???

Left: “different” — yes! Only one left.

✔ Blank 15: different

Now double-check all blanks:

1. All living things need one another. ✔
2. ...need to breathe. ✔
3. The animals produce carbon dioxide... ✔
4. Plants are also food to many animals. ✔
5. Plants get energy from the sun ✔
6. (already did)
7. ...eat the plants get that energy. ✔
8. ...food to other animals. ✔
9. ...for life to exist. ✔
10. provide shelter to animals. ✔
11. helps animals protect themselves... ✔
12. ...from bad weather ✔
13. ...from other dangerous animals. ✔
14. take care of... ✔
15. ...very different. ✔

All words used exactly once. Perfect.
