Know the following:
• How to read a graph and answer question.
• Explain the difference between population and community.
• Calculate population density.
• Classify examples of symbiosis (mutualism, commensalism, and parasitism) by
type and explain your choice

succession
• ESSAY: Explain how two different species can share a habitat but not the same
niche.
