11) After feeding at the surface of the ocean during the day, many ocean organisms migrate to deeper waters. While there, they release ammonia in their urine. Many bacteria use the nitrogen from the ammonia as they make amino acids, which eventually end up in food chains on both land and water. These amino acids may even be used in humans. Which statement best explains these observations? A)All elements in the ocean remain there and are not transferred to other ecosystems.Chemical elements, including nitrogen, pass through food webs and are combined andrecombined in different ways.B)C)Nitrogen is transferred directly from bacteria to humans.D)Chemical elements, including nitrogen, are removed from food webs and eliminated fromecosystems.

Question

11) After feeding at the surface of the ocean during the day, many ocean organisms migrate to deeper waters. While there, they release ammonia in their urine. Many bacteria use the nitrogen from the ammonia as they make amino acids, which eventually end up in food chains on both land and water. These amino acids may even be used in humans. Which statement best explains these observations?

A)
All elements in the ocean remain there and are not transferred to other ecosystems.
Chemical elements, including nitrogen, pass through food webs and are combined and
recombined in different ways.
B)
C)
Nitrogen is transferred directly from bacteria to humans.
D)
Chemical elements, including nitrogen, are removed from food webs and eliminated from
ecosystems.
