It is estimated that animal- or insect-pollinated plants produce 1000 pollen grains for each ovule; wind-pollinated plants produce 1,000,000 pollen grains for each ovule. What does that indicate about pollination systems?
A) Wind-pollinated plants rarely produce seeds.
B) Wind pollination is more efficient than animal-assisted pollination.
C) Wind pollination is less efficient than animal-assisted pollination.
D) Wind pollination is costlier to the plant than animal-assisted pollination.

Explanation:  C) It is less energetically expensive to make pollen than to make ovules; this is because pollen grains are smaller, though more numerous. There must be a discussion of energy investment by a plant for these structures. There also is a cost in feeding animal pollinators, because many animal-pollinated flowers have nectaries.
