Pyramid of energy flow in Florida: numbers in next slide

Section II Energy 4:15; 4:15 - 8:07; 8:07 - 12:00 12 - 15:10

Energy -> Production (growth and reproduction), Maintenance (heat), Waste

10K calories solar radiation:

5% efficient photosynthesis (500 cal), 400 cal maintenance, lost as heat

1% production (100cal)

50cal used by mouse - most used in maintenance, 10 cal stored.

The plants are about 1 percent efficient in trapping solar energy.

Waste energy used by decomposers - but SOME are stored as fossil fuels. Cars are primary and secondary consumers.
