Explanation: Because if the mountain lions, coyotes, and bobcats decrease they arent enough to prey on the deer which causes the deer population to be able to reproduce over time.
Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival
Oceans will increase in temperature due to global warming. This will adversely effect cold water species such as the humpback whale and increase the territory of larger warm water predetors like sharks.
You need more context to the question, however I think I have it figured out.
