Arrange these energy sources from highest to lowest percentage of worldwide use.
Aneli [31]

The correct order of arrangement of energy resources from highest to lowest usage world wide is fossil fuels, nuclear energy and geothermal energy.

A fossil fuel is a energy source formed by the dead remains of living organims over millions of years through the natural process. It includes the coal, petroleum and the natural gas which are the highly used energy resources all over the world. Nuclear energy is the energy generated during the fission or fusion of nuclear reactions which is used to generate electricity. It is one of the low carbon power methods to generate electricity. Geothermal energy is the thermal energy or the heat energy stored in the earth which is used to produce electricity.

Thus, fossil fuels forms the first energy resource to be highly used worldwide.

One adaption to life in flowing water is what?
Alla [95]

Answer:

Explanation:

There are many options, here are a few choices:

Fast moving water tends to be colder than slow water; some of it originates as snow melt on the sides of mountains, for example. For this, animals in fast water tend to be more cold resistant. This is why you do not see fish like freshwater trout in equatorial regions. These animals struggle and die in slow, warm water.

Fast moving water means that if the animal or plant wants to stay put, it must resist the flow. Fish tend to be far more muscular and lean in these places, while insects like stoneflies, mayflies, and other larvae have ways to secure themselves to rocks and plants while growing. Plants develop strong root systems, and algae hold fast in rocky crevices in the river. Some animals also have suction in order to stay in place where there is fast flowing water.

Some animals have to adapt their reproductive systems as well. Because finding a mate is difficult in the sweeping waters, breeding tends to happen all at one time. As an example, salmon have runs, where thousands of fish all swim upriver at once to breed, can dramatically alter the surrounding ecology of the river. Insects like mayflies have hatches, where hundreds of thousands of flies swarm into the air at once to breed and lay eggs.
