Question
1. Orchids (plants) typically supply nectar (a food source) to pollinating insects. As they collect nectar, the insects move pollen among the plants. Nectar is energetically expensive to produce, so "cheater" plants sometimes evolve. These "cheaters" have empty nectaries, so the insects disperse the pollen, but get nothing in return. Assume that a few insects in the pollinator population can tell the plants with true nectaries apart from the "cheaters". A. (6 pts) Describe the 3 conditions necessary for natural selection to act on the insects; explain how each condition would be met for the insects living with orchids. i.

Variation: means changes or differences.
variation are differences between different organisms within or between species.
Variations indicates the similarity and dissimilarity between organisms.
According to variations we can classify different organisms in various classes.
for example the short necked giraffegot variation when small sized Herbs was finished and then they have to eat long shrubs and trees that is why they got variation and then these variations become fixed in genes.
