What does the first law of thermodynamics state?
(Choose all correct answers)
That energy can not be created or destroyed
That energy can be created and destroyed because
I AM GOD!!!!!!!
That energy can be transformed or transferred

Why is 10% of energy lost to the environment as it goes up a trophic level?
Remember this energy is lost not destroyed (per the 1st law of thermodynamics)
Because the animals are lazy and leave 10% of their food behind
Because energy is lost as heat.
Because decomposers generate energy
