Energy: Where Does It Come From? Why Do We Need It?Teacher Printout: Energy Match Cards
I burn hydrogen to make radiant energy.

I convert radiant energy into chemical energy through
photosynthesis. I use the energy for life processes, to grow and reproduce. What I don’t use is
stored within me.
I get chemical energy from eating plants. I store chemical
energy in my cells and use some for life processes, to grow and reproduce. What I don’t use
is stored within me.

I have cells that have stored chemical energy. I am used to transfer energy to other
organisms.

I get chemical energy from eating other organisms. I turn
chemical energy into mechanical energy and heat
energy for life processes such as growth and reproduction. What energy I don’t use is
stored within me.
