A potato plant can reproduce asexually so that one potato can often give rise to many other potatoes. Strawberry plants can reproduce sexually. A potato plant puts a large amount of its energy into growing a tuber, which is the part that humans eat. The tuber can grow large and provide energy for the plant during the winter, or it can be used to grow new potato plants. A strawberry plant, on the other hand, puts much of its energy into growing flowers to attract insects that aid in pollination. After fertilization, the strawberry plant must then also grow seeds as well as fruit to attract animals that disperse the seeds.Based on this information, the asexually reproducing potato plant most likely devotes _______ to reproduction than the sexually reproducing strawberry plant.

There will be a decrease in bees and mice which will cause an increase the black bear population and a decrease in the fox population.
There will be an increase in bees and mice which will cause an increase in the populations of both black bears and foxes.

15. Some redwood trees reproduce both sexually and asexually. Once a tree reaches maturity, it can reproduce with another tree through pollination and fertilization. The tree then disperses thousands of seeds so that some of them might take root. However, a tree can also reproduce asexually. If it falls down, several smaller trees can sprout from its trunk without the need of fertilization.Why is it advantageous for a redwood to reproduce sexually when it could reproduce asexually instead?

It reduces the need to find a mate.
It increases the energy needed to reproduce.
It increases the genetic diversity of the tree's offspring.
It decreases the time needed to reproduce.
