- carbon
- What is the main difference between active and passive transport?
-
active- needs energy (moves from an area of lower to higher concentration)
passive- doesn't need energy (moves from an area of higher concentration to lower) - What do plants froduce after getting energy form the sun?
- oxygen and sugar

- transports substances from one part to the other
- where do autotrophics get energy to make food?
- The sun
- How did the first cell survive?
- used chemicals in its surrounding for energy
- Why is it important for cells to have water?
- most chemical reactions occur in water
- Why does photosynthsis need sunlight?
