Lifeforms in our Solar System

There are several interesting types of organisms that could live in extreme conditions in our Solar System. Use the information in the course videos, discussion articles, and other scientific resources to discuss potential life forms in our Solar System.
Choose one of the planets or moons in our solar system (it can be one used for your previous assignment) and:
Describe three types of life forms that have been discovered on Earth that could survive in the conditions on that planet or moon.
What are the scientific claims about how these organisms survive in extreme condition?
What is the evidence for that claim?
How strong is the evidence? Is there a large body of evidence that this is true or is it still controversial?
