Answer 2

Fossil fuels are considered to be an exhaustible resource because they are available in only limited quantities. Fossil Fuels take thousands, if not millions, of years to replenish and people are using them up too fast so they can not renew.

green leaves still contain a lot of water, once a leaf dies the water leaves the leaf along with all of the cells in the leaf. There is also a possibility that the ignition point changes once the cells die!
