Answer:
pests can evolve defenses against pesticides over time
Explanation:
Pesticides are chemicals employed to kill pests generally. With continuous and indiscriminate use of pesticides, they become less effective because pests population often evolve a defense mechanism against them.
<em>With each usage, more and more pest population survive. Those that survive gradually multiply and pass the survival gene to their offspring eventually giving rise to a population that is genetically insusceptible to the effects of the pesticide. This is generally referred to as evolution by natural selection.</em>

Answer:
Underwater plants will receive less light.
Explanation:
When sea level rises the amount of solar energy in the aquatic environment is decreased and this makes underwater plants receive less light and their development is impaired. This is because, with less sunlight, aquatic plants are unable to photosynthesize and absorb the carbon needed for their metabolism, thus end up dying and diminishing the plant diversity of the sub-aquatic environment.
In addition, many underwater organisms (such as some fish) feed exclusively on these plants. If these plants fail to grow, these fish will be without food and will eventually die; This will also cause problems for the diversity of the underwater environment.
