- it is dependent on the trillions of microorganisms that exist in the soil
5
Q
nitrogen fixing bacteria
A
- legumes
- they take nitrogen from the air and produce nitrogen compounds the plant use in the synthesis of amino acids and protein
6
Q
bacteria in the digestive system
A
- digestive system consists of good bacteria which helps protect you from the bad bacteria
- enzymes are produced to defeat cell wall of plants help with their digestion
7
Q
what is the microbiome
A
a group of organisms where some of the organisms benefit but don’t derive harm to the host or it can be harmed
8
Q
where can the microbiome be found and what is it made up
A
- found in and on all multicellular organisms
- is made up of bacteria, archaea, protists, fungi and viruses
9
Q
What happens when there is a dis balance of the ratio of good to bad microorganisms
A
this is called dysbiosis
10
Q
What is the cause of dysbiosis
A
a dietary change accidental chemical consumption drinking 2+ alcohol beverages a day new medications poor dental hygiene high levels of stress or anxiety unprotected sex
