●● What are the S and J curve related to?
Answer: population growth patterns
●● What is the pattern of growth for the S curve?
Answer: logistic growth pattern
●● What is the pattern of growth for the J curve?
Answer: exponential growth pattern
●● What is the average amount of energy available at one trophic level
as it passes to the next?
Answer: 10%
●● What was the full name of the publication that Darwin published?
Answer: On the Origins of Species by Means of Natural Selection
●● What is the basic idea of natural selection?
,Answer: -organisms can change over generations and individuals with

Answer: evolutionary adaptation
●● Darwin based his theory of natural selection on two key
observations. What are the two observations?
Answer: overproduction (of offspring) and individual variation
●● Overproduction
Answer: -All species tend to produce excessive numbers.
-This leads to a struggle for existence.

Answer: the comparison of body structure between different species
●● What is comparative embryology?
Answer: the comparison of structures that appear during the
development of different organisms
●● Name 3 examples of natural selection in action.
