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.
