Explanation
Bacteria are single-celled organisms that can exist independently, symbiotically (in cooperation with another organism) or parasitically (obtaining nutrients without benefitting the host). They can efficiently utilize a wide range of significant and minor resources in their environment. Darkness itself isn't necessary for bacteria multiplication. Salt is not necessary either and in high quantities, it can actually prevent bacterial growth because it absorbs the water present in the bacteria causing dehydration. Both moisture and a humid environment promote bacterial multiplication as water is necessary for their growth, but dryness inhibits their growth because lack of water makes it difficult for bacterial metabolism to occur.
