The first law of thermodynamics states that energy can't be created or destroyed. if people can't create energy, where do we get energy to do the work

By transforming energy from one type to another.

Explanation:

Energy is not destroyed, it is conserved. During a thermodynamic process, it is transformed from one type to another. The first law expresses a system energy balance. Energy flows in a system (work and heat) are related to changes in system Energy. Thus the first law of thermodynamics says: "The sum of the heat exchanged by a system and the work done by or in a system is equal to the variation of the internal energy of that system."

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
