Name and explain three different ways micro-organism<br>Obtain energy ​
nikklg [1K]

Explanation:

photosynthesis

mutualism

decomposers

chemotrophs

photosynthesis:

Photosynthetic bacteria use the energy of the sun to make their own food. In the presence of sunlight, carbon dioxide and water are turned into glucose and oxygen. The glucose is then turned into usable energy

mutualism:

Some bacteria depend on other organisms for survival. For example, some bacteria live in the roots of legumes, such as pea plants. The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use.

decomposers:

Bacteria known as decomposers break down wastes and dead organisms into smaller molecules. These bacteria use the organic substrates they break down to get their energy, carbon, and nutrients they need for survival.
