90% of the energy at each trophic level is used up in all the organisms daily activities, so when it gets eaten – only 10% of the energy is passed on to the next trophic level.

Bacteria important in this cycle!

Nitrogen fixing bacteria take unusable nitrogen and makes it usable for plants – animals then get this usable nitrogen by eating plants and other animals!
Legumes are peas, beans and clover
Denitrifying bacteria changes Nitrates (usable form) back into nitrogen and releases it into the atmosphere!
