What is the greatest source of canton that enters the ocean from the atmosphere ?
8_murik_8 [283]

Answer:

Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies. Carbon, in the form of carbon dioxide, is even a part of the air we breathe. It is also stored in places like the ocean, rocks, fossil fuels, and plants.

The carbon cycle describes the flow of carbon between each of these places. For example, carbon continually flows in and out of the atmosphere and also living things. As plants photosynthesize, they absorb carbon dioxide from the atmosphere. When plants die, the carbon goes into the soil, and microbes can release the carbon back into the atmosphere through decomposition.

Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.

Some processes release more carbon dioxide into the atmosphere than they absorb. Any process that uses fossil fuels—such as burning coal to make electricity—releases a lot of carbon into the atmosphere. Raising cattle for food also releases a lot of carbon into the atmosphere. These processes that release carbon into the atmosphere are known as carbon sources.

Ideally, the carbon cycle would keep Earth’s carbon concentrations in balance, moving the carbon from place to place and keeping atmospheric carbon dioxide levels steady. However, the carbon cycle is changing because of human activity. People are releasing more carbon into the atmosphere by using fossil fuels and maintaining large livestock operations. Deforestation is depleting Earth’s supply of carbon sinks. As a result, the amount of carbon in the atmosphere is rising.

Which statement best describes an effect of natural selection
I am Lyosha [343]
The answer should be B). Helpful traits passed to the next generation through reproduction.

B is correct because in natural selection, if a population cannot adapt over time it will be “naturally selected” and die off, or be near extinction due to non-adaptive ness. Hope this helped!

Examples of a scientific theory

Scientific theories are testable and make falsifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy).
