What role does photosynthesis play in altering earths atmosphere?

# data[].attributes.body
Photosynthesis plays an important role in the environment for several reasons as it helps clean the air before plants use the carbon dioxide in the air for photosynthesis, the plants produce oxygen as a by-product which all humans and animals need to live and it also makes plants grow providing food for animals who eat plants. Without plants, the world would quickly become uninhabitable for human and animal life. The oxygen would be used up and there would be no food to feed the animals that humans rely on for food.

How are photosynthesis and cellular respiration related to one another in the biosphere?

# data[].attributes.body
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis , in cellular respiration oxygen is combined with hydrogen to form water.

Proteins are typically large molecules that can be built up from chains of amino acids called polypeptides. Nucleic acids are central to the function of living cells. Arranged in a linear sequence within DNA, they code for the structure and function of the body's proteins.

The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth.

Herbivore; an animal that feeds on plants.

Omnivore; an animal or person that eats food of both plant and animal origin.

Carnivore; an animal that feeds on flesh.

an organism deriving its nutritional requirements from complex organic substances.

# data[].attributes.body
an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

# data[].attributes.body
The low rate of energy transfer between trophic levels makes decomposers generally more important than producers in terms of energy flow. Decomposers process large amounts of organic material and return nutrients to the ecosystem in inorganic form, which are then taken up again by primary producers.

Carbon dioxide is a colorless, odorless and non-poisonous gas formed by combustion of carbon and in the respiration of living organisms and is considered a greenhouse gas. Emissions means the release of greenhouse gases and/or their precursors into the atmosphere over a specified area and period of time.

Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Cellular respiration:
The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions of an organism run. The main carrier of energy in metabolism is the molecule ATP.

The c stands for the speed of light, a universal constant, so the whole equation breaks down to this: Energy is equal to matter multiplied by the speed of light squared. The reason is that kinetic energy, or the energy of motion, is proportional to mass.

It implies that energy can neither be created nor destroyed, but can be change from one form to another.

(Law of conservation of matter: A law stating that atoms are not created or destroyed during a chemical reaction. There is the same amount of matter before and after the reaction, the atoms are just rearranged.
