Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (or UV for short) rays from the Sun
They have a cell wall and nucleus but they have no membrane-bound organelles like eukaryotic cells
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.
Composting is a form of waste that uses organic materials to put into plants in order to help them grow and flourish. It saves energy, and it doesn't give off many gasses to help the Earth.
However, it is ineffective on the large scale and cannot be mass produced to help Earth instantly because of the large amounts of inorganic materials.
I believe these are the answers:) best of luck!
