Questions and Answers
What are essential nutrients and why are they important for living organisms?
Essential nutrients are elements that serve as building blocks for compounds that compose living tissue. They are important for living organisms because they are required in relatively large amounts and cannot be manufactured by the organisms themselves.
How do organisms obtain essential nutrients if they cannot manufacture them?
Organisms obtain essential nutrients from their environment.
What is the difference between the flow of energy and the recycling of elements in living systems?
The flow of energy in living systems is a one-time, one-way stream with losses along the way, while elements are recycled within and among ecosystems.
