• ecosystem, community, population, organism

Multiple Choice

Which is the correct order for levels of organization from simple to complex?

• cell, organ , tissue, organ system, organism

• organism, organ system, tissue, cell, organ

Multiple Choice

Which of the following describes what is meant by Natural Selection?
