Please help with 2, 3, and the chart Chapter 13. Evolution and Diversity amongthe Microbes 201 2. es can live in a diverse range of settings and can acquire nutrients from diverse sources. Provide several examples of environments in which microb can live. What sorts of nutrients can microbes use to support their metabolic needs? 3. Microbes are abundant Give a few examples of places microbes live in extremely high numbers. Complete the following table on the four major groups of microbes Microbe Domain Bacteria Prokaryotic or eukaryotic? Protists Virus Archaea

Explanation / Answer

2)

a)Although bacteria are good at adapting to their environments, certain conditions promote bacterial growth more than others. These conditions include temperature, moisture, pH and environmental oxygen.

1) archaebacteria are those bacteria which currently live in extremely salty environmentsor extremely hot environments.

2)There are many types of watery environments. These range from freshwater ponds, streams, puddles, lakes, rivers

3)Psychrophiles and psychrotrophs are types of microorganisms that inhabit cold environments

Most of the thermophilic (hot-water-loving) and halophilic (brine-loving) organisms belong here, as well as sulfur-oxidizers that are mutualists with animals (such as Pogonophora) near submarine hot water vents, and the anaerobic decomposers that produce methane from organic wastes such as sewage and landfills.
Includes chemoautotrophic, photoautotrophic, and absorptive-heterotrophic (decomposer) metabolic types; does not include pathogens or the typical, aerobic decomposers of soils and underwater sediments

b)Microbial metabolism is the means by which a microbe obtains the energy and nutrients it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics, its get nutrients from carbon.

3)Microbes live in the soil, on rocks, inside roots, buried under miles of Earth, in compost piles and toxic waste, and all over the Earth's surface. Microbes are found in boiling hot springs and on frozen snowfields.

1)bacteria- first -pokaryotic

2)protists-three-eukaryotic.

3)viruses- Viruses do not fall under any domain -virsus are considered neither prokaryotes noreukaryotes because they lack the characteristics of living things, except the ability to replicate.

4)archaea -second domain-pokaryotic.
