5.1. Producers
5.1.1. They convert the suns energy to food energy, their energy gets passed to Primary Consumers; however, only 10% of the energy gets passed.
5.2. Primary Consumers
5.2.1. Primary Consumers get 10% of the sun's energy. They pass 10% of the energy they have to Secondary Consumers.
5.3. Secondary Consumers
5.3.1. Secondary Consumers get 1% of the sun's energy. They pass 10% of the energy they have to Tertiary Consumers.
5.4. Tertiary Consumers
5.4.1. Tertiary Consumers get .1% of the sun's energy. They would pass 10% of the energy they have to whoever eats them.
