Answer:
There is no benefit to change this from happening
Explanation:
Typically elephants live until they are over sixty years old. At this age the teeth are worn down and become unusable; some of them may even fall out. When this happens the animal finds it difficult to acquire nutrients and typically becomes malnourished. The animal slowly starves to death and eventually leaves the herd.
There is no reason for this to change from an evolutionary stand point because this animal has already contributed to the herd as a younger elephant. If the older animals continue to live longer this will slow down the movement of the herd as well as consume the resources that the younger elephants need to keep strong and resist predation.
The sick elephants leave the herd and go to the elephant grave yard to pass away and allow the herd to move on.
Explanation:
A coniferous forest is an example of a <u>biome.</u>
<u></u>
Biomes are major ecological communities which occupy a particular space such as deserts forests, and tundras. Each species within a community performs a specified role, called a niche. An ecological niche describes certain conditions required for an organism's survival, its roles and how it responds to resource distribution, along with competition for these resources.
Several limiting factors, restrict the ability of many organisms to thrive in the area; these organisms exist within a particular range of tolerance.

D. fast-moving watercraft.
This question is rather subjective: the answer depends on how the question is interpreted. Many people would say climate change is the greatest risk to water supply, but the question mentions 'Earth's water supply'. It is a fact that the amount of water on Earth has not changed. Climate change is shifting climatic patterns, so some areas experience more droughts, whereas others experience more floods, but the amount of water on Earth still stays the same. My answer is therefore that pollution poses the greatest risk to Earth's water supply. Pollution decreases the amount of water we can safely use without expensive treatment. Some water pollution, such as certain toxic metals, pesticides or endocrine disruptors, simply can't be detected or treated using conventional water testing and treatment. Modern civilisation is resulting in unsustainable amounts of pollution being released into our rivers and lakes, and sooner or later, a threshold of no return will be reached, where ecological collapse will mean we won't be able to rely on these water resources for fresh water anymore.
