Part 1: Choose the correct group for each animal

We are given five animals:

1. Ostrich – A bird (has feathers, beak, lays eggs)
2. Frog – An amphibian (lives in water and on land, has moist skin, undergoes metamorphosis)
3. Fish – A fish (lives in water, has fins, gills)
4. Lizard – A reptile (cold-blooded, scaly skin, lays eggs)
5. Bear – A mammal (warm-blooded, has fur, gives birth to live young)

So, the correct groups are:

- Ostrich → Bird
- Frog → Amphibian
- Fish → Fish
- Lizard → Reptile
- Bear → Mammal

✔ Answers:
1. Bird
2. Amphibian
3. Fish
4. Reptile
5. Mammal

Part 2: Classify these animals in terrestrial or aquatic

Animals shown:
1. Dolphin – Lives in water (ocean), breathes air but spends life in water → Aquatic
2. Horse – Lives on land, walks on four legs → Terrestrial
3. Seahorse – Lives in water (sea), is a fish → Aquatic
4. Hedgehog – Lives on land, small mammal → Terrestrial

✔ Answers:
1. Aquatic
2. Terrestrial
3. Aquatic
4. Terrestrial

Part 3: Read the sentences and label

Words to choose from: Fur, Adaptation, Survive, Tongue, Regulate

Let’s go through each sentence:

#### a) Animals can adapt to ______ their habitats.
- "Adapt" means to change to fit surroundings. The goal is to survive.
- So: Animals can adapt to survive their habitats.

✔ Answer: Survive

#### b) Elephants ______ their temperature with their big ears.
- Big ears help elephants cool down (blood flows through them, heat escapes).
- This is about regulating body temperature.

✔ Answer: Regulate

#### c) ______ happens when animals develop special characteristics to survive.
- This is the definition of adaptation.

✔ Answer: Adaptation

#### d) The Polar Bear has white ______ to help it hide in the snow.
- White fur helps camouflage in snowy environments.

✔ Answer: Fur

#### e) Frogs have long ______ to reach leaves at the top of the trees.
- Frogs use their tongue to catch insects, but here it says “to reach leaves” — likely referring to catching prey near leaves.
- However, frogs don’t use tongues to climb trees. But in context, long tongue is a feature that helps them catch food high up.
- So, the best fit is Tongue.

✔ Answer: Tongue

📝 Summary Explanation:

This worksheet teaches:
- Classification of animals by type (bird, mammal, etc.)
- Habitat classification (terrestrial = land; aquatic = water)
- Adaptations – how animals change over time to survive in their environment
- Vocabulary like *adaptation*, *survive*, *regulate*, *fur*, and *tongue* in context

It's great for building foundational biology skills in second grade!
