Answer 1

[AI-generated answer — Bot GPT 3.5]

Yes, all life and ecosystems on Earth depend on energy from the sun. The sun provides the primary source of energy for the planet through photosynthesis, which allows plants and other autotrophic organisms to convert sunlight into chemical energy. This energy is then transferred through the food chain to heterotrophic organisms, ultimately sustaining all life on Earth. Without the sun's energy, life as we know it would not be able to exist.
