Answer 1

1.friction causes it engines

2.photosynthesis from chemical reactions

3.change food

3.transformation changes light energy into chemical energy.

4.work=force x distance moved.

6.chemical energy changes chemical energy to heat energy.

7.heat energy use heat to perform work.

Answer 2

number one with engine how much number 2 with food I'm at number three with transformation I'm at number four with work how much number five with chemical energy and match number six with it energy and March number seven with photosynthesis
