Answer:
Both organisms benefit in cooperation and competition, but only one benefits in predation.
The decomposers are of two kinds, aerobic decomposers and anaerobic decomposers. The aerobic decomposers need the oxygen from the air to break down the dead and decaying matter into simple salts, sugars and hydrocarbon gases. The anaerobic decomposers do not require oxygen for the break down of dead and decaying matter. They break down the matter into various forms of hydrocarbons, sulphides and nitrogenous compounds.
When a dead and decaying matter gets buried deep within the Earth where there is an absence of the decomposers, it takes the form of crude oil, coal, peat, asphalt, and natural gas. The matter gets compressed by the weight of the rocks above and changes its form.
Answer:
Scanning electron microscope.
Explanation:
It is scanning electron microscope because it is an electron microscope that produces image with three dimensional structure of the specimen by scanning the surface of the specimen using beam of electrons that is been focused causing an interaction between the electrons and atoms of the specimen which send signals that indicates information about the specimen.
