I need two paragraphs explaining how carbon is transferred within and between organisms and the environment.

Answers

Answer:

Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.

For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

What is the relationship between the curve seen in the graph and the environmental health of the oceans?
An increased population will result in the improved environmental health of the oceans due to more scientists inventing better technologies.
An increased human population size means that the ocean's resources will be used more efficiently.
As the population goes up, the oceans are more likely to be used as a habitat for humans.
As the population increases, more demands are put on the ocean to support human life.

Answers

Answer:

As the population increases, more demands are put on the ocean to support human life.

Explanation:

Many countries rely on the ocean for transport and as food sources. Over fishing has continuously been a growing problem as more and more fish are required to sustain populations as well as support more gourmet markets. A higher population will also lead to higher trade rates as more materials that aren't available in one country will need to be imported from others.

The reaction to their effort resounded throughout the country. On the first day of school, Governor Orval Faubus called upon the Arkansas National Guard to bar the nine students from entering the school, and a mob of protesters harassed and threatened them. In response to this embarrassing spectacle, President Eisenhower sent federal troops into Little Rock to protect the students, who became known as the Little Rock Nine.
