Amarine biologist explains that salmon show overproduction, which allows natural section to work. what is "overproduction"? the birth of more males than females the birth of more offspring than can survive more available eggs than available sperm more available sperm than available eggs

The correct answer is - The birth of more offspring than can survive.

Explanation:

Overproduction takes place when species reproduce many more offspring than can really survive in nature. It is because of limited resources in a particular ecosystem.

Overproduction leads to competition for resources. It is one of the factors that can affect the process of natural selection. It can be responsible for the adaption and variation in species. Overproduction improves the genetic line by supporting the strongest characters by the survival of the fittest.

Thus, the correct answer is - The birth of more offspring than can survive.

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
