Answer 1

★ Bacteria :

♦ They are very small living things that can only be seen with special equipment (a microscope). Bacteria exist in large numbers in air, water, soil, plants and the bodies of people and animals. Some bacteria cause disease .

★ In Daily Life :

♦ Bacteria in the digestive system break down nutrients, such as complex sugars, into forms the body can use. Non-hazardous bacteria also help prevent diseases by occupying places that the pathogenic, or disease-causing, bacteria want to attach to. Some bacteria protect us from disease by attacking the pathogens.

or

♦ They help digest food, make vitamins, and play other important roles. Humans also use bacteria in many other ways, including: Creating products, such as ethanol and enzymes. Making drugs, such as antibiotics and vaccines.

or

♦ We could not survive without all the bacteria living on and inside us – they act as part of our immune systems, digest foods such as dairy that we cannot break down ourselves and provide us with nutrients and minerals that we need to survive.
