Where does food come from?
The Sun gives energy to the plants, the cows eat the plants, and we eat the cows!
Why are leaves like food facotories?
becuase they take raw materials and make them into food just like food factories
Why is water important to living things?
Becuase without water everything would die
what role does osmosis play in living htings
It makes it so that we can obsorb nutrients and oxygen. to get into and out of cells.
How do living things get energy from food?
The body obsorbs the food and we add oxygen and water to get energy
Why do we breath?
so we can get oxygen to our cells and brain so that we cane get rid of waste products like water and carbon dioxide.
What is respiration?
Is the process in wich organisms combine oxygen and water to release a chemicall energy. ande water.
