Biology Review

How does a plant take in nitrogen?

• A plant takes in nitrogen as ammonium (NH4+) after a decomposing animal has released the ammonium.
• A plant takes in nitrogen as atmospheric nitrogen (N2) captured directly from the atmosphere.
• A plant takes in nitrogen as nitrates (NO3-) after nitrogen has been transformed by bacteria.
• A plant takes in nitrogen as nitrites (NO2-) received directly from other plants.

If the population of bobcats decreases in a food chain, what will most likely be the long-term effect on the rabbit population?

• It will increase only
• It will decrease only
• It will increase then decrease
• It will decrease then increase

The following pictures represent four populations in a food chain.
Which sequence best represents the transfer of energy between these organisms?

• The amount of energy increases at each successive level, from D to A.
• The total amount of energy needed to sustain the pyramid enters the ecosystem at level C.
• The total amount of energy at level D is less than the total amount of energy at level B
• The amount of energy is identical in each level of the pyramid.
