Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.
This is the male reproductive cell, and then, when it travels through the Stigma, then, it goes on the top of the flower, then, a bee carries it to another plant's female reproductive cell, then the cells go into the embryo and create a plant's seed.
The decrease of predators would make the elk population thrive, because there would be nothing to hunt them down. And with an increase of food, the elks would have enough to eat therefore the elks would not die from hunger.
