- attractive
- 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.
- How is respiration similar to burning?
- They both give off heat and energy but respiration is at a cooler temperature, and it can take place in your body and burning can not.
- How do plants and animals depend on each other
- plants give off oxygen and take in carbon dioxide and animals give off carbon dioxide and take in oxygen and we get food from plants.
- How are humans changing the natural enviorments?
- they are poluting the air and changing forests to like shoping centers.
