Factors that could affect the current oxygen and carbon dioxide levels?

Explanation:

There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:

Burning of fossil fuels increases the level of carbon dioxide.

Cleaning agricultural land increases the level of carbon dioxide.

The availability of nutrients in plants affects the synthesis of oxygen.

The intensity of the sunlight can increase or decrease the synthesis of oxygen.

Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.

The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.

An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.

A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
