Describe at least three ways bacteria are beneficial to humans or natural ecosystems and provide an example for each. How are bacteria harmful to people?

Solution

The various ways in which the bacteria are beneficial to humans are:

1.The first is that they are considered to be the decomposers which help to break down organic materials present in the soil. For example the bacteria is useful to decompose the dead matter which included the   fallen trees.These trees are transformed into usable nutrients for living organisms by the bacteria.

2.The second important advantage is that they cycle nutrients which includes gases like nitrogen and carbon, in order to transform the various nutrients into various kinds of usable forms. For example, the bacteria helps to transform carbon gas into carbon dioxide gas.This is very important for photosynthesis which is defined as the process of making food by plants.

3.Another important advantage is that the bacteria helps to transform gases like nitrogen into nitrates or nitrites, which helps plants to grow.

The bacteria are harmful in the following ways:

1.They cause waste and diseases as the food which is not properly stored starts to rot due to bacteria in air.

2.They also produce various toxins which results in the bad odors and the decay of organic material. These toxins lead to food poisoning and the health of the person can deteriorate.
