Can we live without bacteria?
No, we cannot survive without bacteria. One of our main human necessities is digesting food, and without bacteria, we cannot do that. Bacteria also ferments food that we consume, like yogurt or bread.

What conditions are needed by bacteria to thrive?
Bacteria can live in hotter or colder places than humans, but they feel better in a warm, moist and protein rich environment. Some bacteria thrive in extreme heat or cold. Some can survive under highly acidic or extremely salty conditions.

-Where could we find bacteria  beyond Earth?
We can find the bacterias on the living things they are most found in the bodies of the living things. There are other bacterias that we can find in the food and we can find bacterias in the surface of the things.

What is the percentage of bacteria in your body mass?
- A normal individual contains on aproximedly around 30 trillion human cells and 39 trillion microscopic organisms on its body.

No, we can't live without bacteria. Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don't get a chance to grow and cause disease.

What living things require bacteria?
The only ones are the humans.

-What conditions are needed by bacteria to thrive?
-What other taxonomic groups depend on similar conditions or resources?
Bacteria are the one most ancient if not the most ancient type of life that we know. Therefore the origins of life and the study of it is almost always related to this living things. The conditions of life generally tend to vary but there are some of them are constant and are required in all forms. This are water, some type of energy or digestion and a somewhat safe enviroment. This are conditions that as far as we know are present in almost all types of life as we know them. This go from the birds in the sky to us mammals on land to the creatures that live in the deep sea. How ever as we previously mentioned some other more complex living things such as humans we need more specific conditions. For example a balanced diet. These kinds of things are the ones that prove that for beings such as bacteria thriving is more likely just that due to this same simplicity these living creatures get to live less and be more productive on there lives.

What is the percentage of bacteria in your body mass?
The percentage of microorganisms in a human's body mass, is about 1 to 3 percent of the hole human body. Within this microorganisms, there is bacteria in the body. Bacteria can be found in the skin, mouth, nose, but most of this bacteria is found in the human gut. As a reference or example, a man that weights 70kg, has a height of 170 centimetres, and has an age between the range of 20-30 years old, usually has an average of a total of 39 trillions of bacteria in his body. All in all bacteria plays a fundamental role in human health and they increase as the host grows, since they live within us all our life process.

-What is the percentage of bacteria in your body mass? The human body contains trillions of microorganisms outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass in a 200-pound adult, that's 2 to 6 pounds of bacteria, but play a vital role in human health.

-Where could we find bacteria on Earth?
Bacteria can be found anywhere where there is other live. Bacteria are very small systems which are usually found in living bodies but can also be found on surfaces and in the air.

This is a collective statement. We will build this wall by putting together our ideas, conclusions and observations about the Tiny Ecosystem Lab and its relation to Life forms and the Origin of Life on Earth.
