Answer:
Biomass
Step-by-step explanation:
There are two kinds of energy sources renewable and nonrenewable.
A renewable recourse is a resource that can be renewed. This means that it can replenish itself, before we can deplete it completely. A good example of a renewable energy source would be the sun.
A nonrenewable recourse is a resource that cannot replenish itself and can often, only be used once. A good example of a nonrenewable energy source is coal, because we cannot make more coal within our lifetime.
