1.Eubacteria: These bacteria appear the initial concept about bacteria, so it could call true bacteria. They have rigid cell wall that can keep the shape of cell. Most of bacteria include these bacteria. they can be found almost everywhere and kill thousands upon thousands of people each year, but also serve as antibiotics producers and food digesters in our stomachs.

2. Archaebacteria: These microbes are prokaryotes, meaning they have no cell nucleus or any other membrane-bound organelles in their cells. They and bacteria similar size and shape, although a few archaea have very strange shapes. For examples, Halobacterium found in salt environment. Then Sulfur loving bacterium found near deep sea vents.

3. Protista: any eukaryotic organisms that is not animals, plant or fungi. They are unicellular, some are colonial or multicellular, they do not have specialized tissue organization. Most of Protista live in water, some in moist soil or even the body of human and plants.

4. Fungus: They are eukaryotic organism that include yeasts, molds, and mushrooms. Fungus have cells with nuclei. Also, they are heterotroph, so they get food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. They do not photosynthesise. Most of fungus are small size, so they are inconspicuous.

5. plant: One of five big group of living things. Manly multicellular, generally photosynthetic eukaryotes of the kingdom plantae. They are autotrophic eukaryotes, so they can make their own food. They grow in the ground with roots below, so they can get water from root. Plants include trees, herbs, grasses, vines, ferns, mosses, and green algae.

6. Animal: animal are eukaryotic, multicellular organisms. They can hunt the food and eat like people. All animals are heterotrophs, so they feed directly or indirectly on other living things. Among Linnaean classification, they are under the domain Eukaryote. Most of animal have communal living.
