Key differences, features, and comparative analysis of Law and How the ecosystem obeys it.
| Law | How the ecosystem obeys it |
|---|---|
| First Law | Energy is neither created nor destroyed — the sun's energy is converted (fixed by autotrophs into food), not made. Flow is unidirectional: sun → producers → consumers. |
| Second Law | Ecosystems are not exempt. They need a constant supply of energy to synthesise the molecules they require, in order to counteract the universal tendency toward increasing disorderliness (entropy). |
