A good example of someone that helps the environment is Greta Thunberg who is a young lady that is a big environmental activist amount other things.

Genes are the code and when processed by a cell, it will result into a particular specie.

Plants produce oxygen for us to breathe, and in exchange they take the gas we breathe out: carbon dioxide.
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. Hope I’ve helped ;)
