Answer 2

The importance of wild animals does not depend on how much they can produce for us. They are important because they all even each other out into a balanced and effective ecosystem, along with abiotic factors. The apex predators are the most important, because they act as a governing body of sorts for the ecosystem. They make sure that none of the prey eat too many plants, or have offspring beyond the carrying capacity of the ecosystem. Without them, as seen in Yellowstone National Park with elk after the wolves there were slowly killed off by humans, the preys’ numbers will get out of hand, and they will decimate the plant populations, causing devastating trophic cascades that effect all biotic and abiotic factors in the ecosystem. The prey and supporting predators are also very important, because the predators obviously all depend on the prey to live, and the supporting predators might keep other prey populations in check. No one knows what the overall purpose of all wild animals is, and there might not be one, but in my opinion, they are important anyway because they all have lives, and they all support a very organized system.
