Which one best explains the difference between a population and a community?

• One place vs many places

• One type vs multiple types of species

• Same vs different climates

• If the total size of a population is big enough, it is called a community

Which of the following best defines an ecological niche?

• A specific geographic area where a species lives
• The role and position a species has in its environment
• A type of habitat destruction
• A method of categorizing species based on their diet

What is the "Fundamental rule of niches"?

• 1+1=2

• Many species can occupy the same niche. Plenty of room for everyone.

• No two species can permanently occupy the same exact niche.

• Ecosystems change over time

What is competitive exclusion?

• A principle stating that two species competing for the same resources cannot coexist. One may drive the other out.

• A principle stating that two species can always share the same resources
• A principle stating that competition between species is beneficial for both
• A principle stating that species always find a way to coexist
