Step-by-step solution for: Grade 4 science worksheets
Let’s go through each question one by one. I’ll explain what each term means and then match it to the correct answer.
---
1. The process of producing young animals or plants is called...
→ This is about making new life — babies, seeds, etc.
✔ Answer: reproduction
---
2. Animals that have a backbone are known as...
→ These are animals with spines — like dogs, cats, humans.
✔ Answer: vertebrates
---
3. Large areas of land covered with trees are called...
→ Think forests — big green places full of trees.
✔ Answer: forests
---
4. A place where an animal lives is called its...
→ Like a home for animals — could be a nest, cave, pond, etc.
✔ Answer: habitat
---
5. The process whereby certain species pass on offspring is referred to as...
→ Again, this is about having babies or young ones. Same as #1.
✔ Answer: reproduction
*(Note: Some might say “breeding,” but in science class, “reproduction” is the standard term.)*
---
6. Organisms that cannot make their own food are called...
→ They need to eat other things — like animals, fungi, some bacteria.
✔ Answer: heterotrophs
---
7. The movement of animals from one place to another within a habitat and back environment is known as...
→ This sounds like migration — moving seasonally and coming back.
✔ Answer: migration
---
8. The ability of an organism to survive in surrounding temperatures (hotness or coldness) is called...
→ How well something handles heat or cold.
✔ Answer: temperature tolerance
*(Sometimes called “thermal tolerance,” but “temperature tolerance” fits best here.)*
---
9. Plants that grow in water are called...
→ Water plants — like lily pads, seaweed.
✔ Answer: aquatic plants
---
10. Animals that live both on land and in water are called...
→ Frogs, salamanders — they can do both!
✔ Answer: amphibians
---
11. The process by which living organisms break down food to be converted into nutrients and not gas is called...
→ Breaking down food inside the body to get energy and nutrients.
✔ Answer: digestion
---
12. Temporary growth...
→ Hmm… this seems incomplete. But if we think about temporary changes in growth due to environment, maybe “adaptation”? Wait — let’s look at options.
Looking at the list again — perhaps this is meant to be “temporary change in behavior or structure?” Actually, looking at common terms, maybe it’s referring to acclimatization — short-term adjustment to environment.
But wait — the word given is “temporary growth.” That doesn’t fit any standard term perfectly. Let me check the original image context...
Actually, re-reading: “Temporary growth” — maybe it's a typo? Or perhaps it’s meant to be “temporary change”? In many worksheets, this refers to acclimatization.
But since “acclimatization” isn't listed in your options... Wait — you wrote:
> 12. temporary growth → ?
And the options include: adaptation, acclimatization, evolution, etc.
In biology, acclimatization is short-term physiological change — like getting used to high altitude. It’s not permanent growth.
So likely, the intended answer is: acclimatization
✔ Answer: acclimatization
---
13. Any action or activity that can be carried out under water is called...
→ Things done underwater — swimming, diving, fishing.
✔ Answer: aquatic activities
*(Though sometimes just “underwater activities,” but “aquatic” is the scientific term.)*
---
14. Which of the following is NOT a vertebrate?
Options: fish, bird, insect, mammal
→ Fish, birds, mammals all have backbones. Insects do NOT.
✔ Answer: insect
---
15. What type of soil retains water?
→ Clay holds water best. Sand drains fast. Loam is balanced.
✔ Answer: clay
---
16. Which part of plant helps in photosynthesis?
→ Leaves — they have chlorophyll and catch sunlight.
✔ Answer: leaf
---
17. Which animal lays eggs?
Options: dog, cat, chicken, cow
→ Only chickens lay eggs among these.
✔ Answer: chicken
---
18. Which of the following is a carnivore?
Options: lion, deer, rabbit, goat
→ Lions eat meat. Others eat plants.
✔ Answer: lion
---
Now let’s compile all answers clearly:
