Week 3 Biology
In this week’s discussion you will be exploring energy and how it’s captured, released, and used by all living creatures. For your primary post, respond to one of the following three topics and address all of the questions. Also, please reply to at least one fellow student on any topic.
Topic 1 : The phytoplankton that brought Earth to life. Review the video (1)* about the “phytoplankton that brought Earth to life” from the link given below. In this clip, Penny Chisholm discusses a tiny phytoplankton called Prochlorococcus. Based on that video, address the following:

(a) What is the importance of Prochlorococcus for life on the planet Earth today?
(b) In the video, Dr. Chisholm tells us that Prochlorococcus samples from different environments that are genetically different. What does this tell us about the relationship between organisms and their environments?
(c) Share how this relates to this week’s lessons.
