Ecosystems____
1 They need a constant supply of energy to synthesise the molecules and to counteract the universal tendency toward increasing disorderliness
2 They dont require constant supply of energy
3 Exempt from the Second Law of thermodynamics.
4 Both 1 and 3
Explanation:
Ecosystems are not exempt from the Second Law of thermodynamics. They need a constant supply of energy to synthesise the molecules they require, to counteract the universal tendency toward increasing disorderliness.
