1. Ecological Law:• Mass and energy conservations arevalid for ecosystem.• This law is used widely in ecologicalmodelling, population dynamics, bythe allometric principles and in theexplanation of numerous ecologicalobservations
2. Ecological Law:• All processes in ecosystems areirreversible and are accompanied byentropy production and exergydestruction.• This law gives an understanding of theenergy utilization in ecosystems, heatproduction by respiration and all energybalances for ecosystems or organisms• Irreversibility (time arrow) is a prerequisitefor the ecosystem development, theevolution and the his<strong>to</strong>ry (Prigogine).
