Why do carnivorous plants have scapose inflorescences (i.e., flowers on long stalks)?
a. The flowers help to attract insects to the traps. b. Carnivorous plants typically live in bogs, and there are few insects there. c. They protect the insects that pollinate the flowers from the traps. d. Because the digested insects provide lots of nutrients, so the flowers can be very large. 15. Nutrient cycling is the process by which nutrients are used by many different organisms and changed in chemical form through the biological processes of those organisms. As an example, we discussed the nitrogen cycle in some detail. What is nitrogen fixation? a. The conversion of nitrogen gas (N2) into a form that can be used by organismal metabolism. b. The release of nitrogen gas (N2) from nitrogen-containing compounds in organic matter. c. The repair of bonds in nitrogen gas (N2) that have been broken by ultraviolet light. d. An obsessive and unhealthy concern with nitrogen gas (N2). 16. What is denitrification? a. The conversion of nitrogen gas (N2) into a form that can be used by organi
