#### Section 1: Choose the correct group for each animal

This section asks you to classify animals into groups based on their characteristics. However, the groups are not provided in the image. Typically, such classifications could be based on habitat (e.g., terrestrial, aquatic), diet (e.g., carnivore, herbivore), or other features. Since the groups are not specified, I will assume a common classification: terrestrial (land-dwelling) vs. aquatic (water-dwelling).

- Ostrich: Terrestrial (lives on land)
- Frog: Both (can live on land and in water)
- Fish: Aquatic (lives in water)
- Lizard: Terrestrial (lives on land)
- Bear: Terrestrial (lives on land)

Answer:
- Ostrich: Terrestrial
- Frog: Both
- Fish: Aquatic
- Lizard: Terrestrial
- Bear: Terrestrial

#### Section 2: Classify these animals in terrestrial or aquatic

This section explicitly asks you to classify the animals as either terrestrial (land-dwelling) or aquatic (water-dwelling).

- Dolphin: Aquatic (lives in water)
- Horse: Terrestrial (lives on land)

- Hedgehog: Terrestrial (lives on land)

Answer:
- Dolphin: Aquatic
- Horse: Terrestrial
- Seahorse: Aquatic
