Sewage
Nitrogen can be broken down through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into compounds like ammonia that plants can use. Another way nitrogen can be broken down is through denitrification, where other bacteria convert nitrates back into atmospheric nitrogen gas.
a chemical called antibiotic that limit the growth of or kills other bacteria.
Plants, Animals, and Bacteria
Bacteria
Tooth enamel is broken down when bacteria feed off the sugars on your teeth. Their waste is the acid that breaks down your enamel.
Its in the millions - faeces is made up of mucus, waste from the body, broken down tissue and bacteria
Any natural, organic waste that falls onto the forest floor, is broken down by bacteria, moulds, and insects, and the nutrients are returned to the soil.
Most of it would be because feces is the result material that is organic.
Biodegradable waste is a type of waste, typically originating from plant or animal sources, which may be broken down by other living organisms. Waste that cannot be broken down by other living organisms may be called non-biodegradable. Biodegradable waste can be commonly found in municipal solid waste (sometimes called biodegradable municipal waste, or BMW) as green waste, food waste, paper waste, and biodegradable plastics. Other biodegradable wastes include human waste, manure, sewage and slaughterhouse waste.
Trees get rid of waste products through a process called transpiration, where they release excess water and gases through tiny pores on their leaves called stomata. Trees also shed leaves, bark, and roots as they age, which helps to remove waste products from their systems. Additionally, some waste products may be broken down and recycled by fungi and bacteria in the soil surrounding the tree.
The municipal waste treatment phase that uses aerobic bacteria to decompose and digest waste solids is called the biological process or the activated sludge process. In this process, wastewater is mixed with bacteria-rich sludge in an aerated tank, creating an oxygen-rich environment that promotes the growth of aerobic bacteria. These bacteria break down and digest the organic matter in the waste solids, resulting in the purification of the wastewater.
This process is called Bioremedation
