No, not all gases have a distinct smell. Some gases are odorless and cannot be detected by smell alone.
The smell when things are rotting is caused by the release of gases such as hydrogen sulfide and ammonia as organic matter decomposes. These gases are produced by the action of bacteria and other microorganisms breaking down the material. The odor is typically described as foul or putrid.
The smell in mangroves is caused by the decomposition of organic matter, such as fallen leaves and detritus, in the waterlogged and anaerobic soil. This decomposition process produces gases like methane and hydrogen sulfide which contribute to the characteristic smell of mangrove ecosystems.
