Langford McDaniel CFA review 2023

Which best describes biodiversity?

• Biodiversity is beneficial because it increases the chances of a species survival to reproduce and pass on their traits

• Biodiversity is harmful because it decreases an organisms chance of survival

• Biodiversity is neither harmful or beneficial

• Biodiversity is beneficial becuase it decreases an organisms chance of survival

Would biodiversity increase or decrease an organisms chance of survival? (Example different size/shape bird beaks)

• Increase because the organisms with the least favorable traits will survive and reproduce

• Increase because the organisms with the most favorable traits will survive and reproduce

• decrease because the organisms with the least favorable traits will survive and reproduce

• decrease because the organisms with the most favorable traits will survive and reproduce

Based on the food web which level of consumers would receive the greatest amount of energy and why?

• primary consumers because they get their energy from the secondary consumers

• tertiary consumers because they get energy from the secondary consumers and are at the top

• secondary consumers because they get their energy from primary consumers

• primary consumers because they get their energy from the producers which contain the most energy

NGSS.MS-LS2-3

Which level contains the most energy and why?

• tertiary consumer because they are at the top of food chain and get 100% of energy

• producers because they are where 100% of the energy is located at bottom of the pyramid

• Primary consumers because they are eating the producers which have the most energy

• None of the above

Based on the food pyramid what would phytoplankton be classified as and what is true about them?

• tertiary consumers because they have the most energy and eat all the other organisms

• producers because they are located at the bottom of the pyramid, contain the most energy, and would produce oxygen because they are plants

• producers because they are located at the bottom of the pyramid, contain the least energy, and would produce oxygen because they are plants

• producers because they are located at the bottom of the pyramid, contain the most energy, and would not produce oxygen because they are not plants

If phytoplankton's are producers how could they benefit humans?

• They produce carbon dioxide for us because they are plants

• They help create a lot of biodiversity

• They produce oxygen for us cause they are plants

• They don't benefit humans at all
