I think its called a decomposer.
it's called decomposing (I think) because it breaks down from other organisms (hope this helps!)
Saprotrophic bacteria and fungi secrete digestive enzymes into dead organic matter in order to decompose it, and recycle it's nutrients (such as carbon, nitrogen, and phosphorous)
All bacteria that are called saprophytes break down the remains of dead organisms. These bacteria recycle oxygen, nutrients, and other valuable resources that can be used over by other organisms. THE CORRECT ANSWER: nitrogen compounds
No, not all organisms use organic compounds for energy. Some organisms, such as certain bacteria, are capable of using inorganic compounds like hydrogen sulfide or ammonia as an energy source through a process called chemosynthesis. These organisms do not rely on organic compounds for their energy needs.
Such organisms are called decomposers, which include micro fungi and bacteria . They decompose dead and decaying organic matter. An organism that decomposes decaying organisms leaf litter and other types of dead organic matter is called a saprobe, saprotroph ,saprophytic .
Decomposers :)
its not the Golgi apparatus, or cellular respiration. it is the lysosomes that recycle organic material. "Lysosomes also use their hydrolytic enzymes to recycle the cell's own organic material, a process called autophagy." - Biology Sixth Edition, Campbell - Reece
Saprophytes are a classification of bacteria that gets their nutrition from dead organic matter. These are more commonly called decomposers.
Bacteria =========================== Specifically a particular type of bacteria that live in nodules on the roots of certain plants (eg the Legume family) called "Nitrogen Fixing Bacteria" . Not other bacteria decompose organic material and release nitrogen back into the atmosphere.
Saprobes
Organisms that manufacture organic nutrients for an ecosystem are called producers. Most plants are producers, as they manufacture organic nutrients through the process of photosynthesis.
Organisms that manufacture organic nutrients from inorganic substances, such as carbon dioxide, are called primary producers. They are also referred to as autotrophs.
