> Why is it said that the sun provides energy either directly or indirectly to all living things on earth? Please help :^

I would say that the sun directly gives energy to plants, and animals eat those plants. People eat the animals that eat those plants and the sun's energy is indirectly continued along like that.

Or something along those lines lol

1. dermis

2. chemical

3. urine

4. viruses

5. antibodies
