Question

13 multiple choice 2 points which of the following organisms is not ultimately dependent on the sun as a source of energy? a night - blooming flower is pollinated by night - flying bats. an underground earthworm avoids the sun. all of the choices are ultimately dependent on the sun. all of the choices are not ultimately dependent on the sun. a cave fish feeds on debris that washes down to it.

Explanation:

• For the night - blooming flower: The flower uses energy from photosynthesis (which depends on the sun) to grow and produce nectar. The bat, which is an animal, ultimately depends on the sun as it gets energy from the food it eats (which may be plants or plant - eating animals, and plants depend on the sun for photosynthesis).
• For the earthworm: Earthworms eat organic matter. This organic matter is either plant - based (which depends on the sun for photosynthesis) or from plant - eating animals (which also have an indirect dependence on the sun).
• For the cave fish: The debris it feeds on is likely from organic sources that either directly (plants) or indirectly (plant - eating organisms) depend on the sun for energy.

Answer:

C. All of the choices ARE ultimately dependent on the sun.
