Diversity in Ecosystems
This chapter shows us that the survival of the
ecosystems relies on both external and natural
factors.
We also learn about Canadas plans or objectives
to protect its ecosystems.
You can form your decisions and take a stand with
them in written form in order to help save
Canada's ecosystems.
With the given knowledge we should can compare
natural and artificial ecosystems.
And asses the impact of the introduction of
exotic species.

Change and stability in Ecosystems
This chapter teaches us to relate photosynthesis
and cellular respiration with carbon, oxygen and
cycling energy.
