PLEASE HELP ME please and thank you.

Awic dietitian is meeting with a client who has an infant and a young child. the mother says that the young child is a very picky eater and will only eat crackers and juice. the health worker notices that the child's hair is brittle, his nails tear easily, and the skin inside his lower eyelids is very pale. these are all signs of iron deficiency.

What would happen to the nutrients in an ecosystem if decomposers, such as bacteria, didn’t exist there?

Hey me with this one❤❤❤❤ every organism needs food. does a cell also need it? explain very briefly.
