What kind of useful jobes do bacteria perform?

Bacteria play crucial roles in various ecosystems and human activities. They are essential for nutrient cycling, such as nitrogen fixation, which enriches soil for plant growth. In biotechnology, bacteria are used for bioremediation to detoxify polluted environments and in the production of antibiotics, enzymes, and fermented foods. Additionally, they aid in digestion and maintain gut health in humans and animals.


Why are resistant spores useful to bacteria?

Resistant spores are a survival mechanism for bacteria in harsh conditions. They protect the bacteria's genetic material from damage and allow them to remain dormant until conditions improve. This increases the chances of the bacteria's survival and enables them to re-establish themselves when conditions become favorable again.


Some heterotrophic bacteria are useful for?

Some heterotrophic bacteria are useful for decomposing organic matter, helping with nutrient recycling in ecosystems, and aiding in wastewater treatment processes. Additionally, certain heterotrophic bacteria are used in bioremediation to break down pollutants and contaminants in the environment.


Do bacteria have enzymes for performing metabolic activities?

Yes, bacteria have enzymes that help them perform various metabolic activities such as breaking down nutrients, synthesizing molecules, and releasing energy. Enzymes are essential for the functioning and survival of bacteria.
