Exothermic
As it decays bacteria catalyses a chemical reaction to release methane and heat. When you burn it a chemical reaction occurs between the biomass and oxygen that releases light and heat. Biomass contains potential energy that can be chemically released.
Endothermic reactions are characterized by the release of heat during the reaction. A typical example is the combustion of methane, which when combined with oxygen releases water and carbon dioxide.
an exothermic reaction
An exothermic reaction.
Exothermic reactions release heat energy, so they would produce heat (increase in temperature). This can easily be tested by touching the container with your hands, or by using a thermometer. The opposite is an 'endothermic' reaction, which absorbs energy and feels colder.
Because during this reaction no new substances release.
Because during this reaction no new substances release.
Endothermic reactions are characterized by the release of heat during the reaction. A typical example is the combustion of methane, which when combined with oxygen releases water and carbon dioxide.

There are various substances that animals release to the environment. Carbon dioxide is one of substances which is then taken in by plants for purposes of photosynthesis.
The thermal energy released when you strike a match comes from chemical energy of the substances that make up the match head. These substances go through a chemical reaction to give different new substances (products) with less energy (considered at the initial temperature), and thermal energy that flows to the surroundings (heat) at a lower temperature.
When people say you need oxygen for a fire, they mean elemental oxygen, O2, in which it is not chemically combined with anything else. In a fire oxygen chemically combines with some flammable material to form new substances and release energy. The oxygen in water is already combined with hydrogen and the energy is essentially already released. In fact, you get water as a product when you burn hydrogen gas or a flammable hydrogen compound. Water is used to put out fires mainly because it is very good at absorbing heat, and so can rob a fire of the heat it needs to keep burning. As a secondary effect, it can also cut off a fire's oxygen supply.
The energy release of an exothermic reaction is released to the surroundings.
