Answer 1

- to find each other — Yes. Echoes can tell animals where other animals are; some use calls to locate or identify conspecifics.
- to find food — Yes. Echolocation is commonly used to detect, locate and track prey.
- to find their way — Yes. It’s used for navigation and avoiding obstacles in the environment.

- to find warmer areas — No. Echolocation detects objects and surfaces, not temperature.
- to find sunlight — No. Echolocation works with sound, not light, so it doesn’t locate sunlight.
