Does flow of energy in an ecosystem obey the First Law Of Thermodynamics ?
Energy flow in an ecological community must obey the first law of thermodynamics. Using the grazing food chain as an example, For the harvest of solar energy by plants in the production of plant tissues, the first law of thermodynamics requires that the amount of solar energy captured by the plants remain the same before and after the transformation the energy involved cannot be created nor destroyed. For every thousand calories of solar energy captured and transformed by plant, there remain a thousand calories afterward.
