Oogenesis produces 1 viable cell and spermatogenesis produces 4 viable cells. Details about gametogenesis can be found below.

Gametogenesis is the process by which gametes are produced. Gametogenesis consists of two processes namely;

Oogenesis is the formation and development of an oocyte or ovum while spermatogenesis is the process of sperm production in the testes.

Oogenesis results in the formation of only one viable egg cell while spermatogenesis results in the formation of four spermatids.

Explanation:

Carbon and oxygen are independent of each other but are very closely connected as well as interdependent. The following article will cover information that will help you understand the carbon-oxygen cycle in detail.

Life on planet Earth continues due to the presence of organic as well as inorganic nutrients present in nature. These nutrients need to be continuously recycled. If this doesn’t happen, all the nutritive resources in the world will get extinguished completely. No nutrients means no life on Earmeano, for the life cycle of every living being, unicellular or multicellular organism to sustain, recycling the nutrients is very important. One of the important cycles is the carbon-oxygen cycle.

The Process of Carbon-Oxygen Cycle

There are four steps involved in the completion of this cycle. These methods are discussed below:

Photosynthesis

Plants undergo photosynthesis which helps them produce energy and food for themselves. During this process, plants take in carbon dioxide (CO2) and absorb water (H2O) with the help of their roots. The chlorophyll present in the leaves and the energy from the sun, help convert CO2 and H2O into Oxygen O2, sugar, and water vapor. Oxygen (O2) is released by plants as a by-product of the atmosphere.

Formula for Photosynthesis

CO2 + H2O + Light ———-> (CH2O) + O2

The carbon dioxide from air and water from the soil in presence of light (energy) is taken by the plants and converted into carbohydrates and oxygen as by-products.

Respiration

Just as plants carry out photosynthesis, animals carry out respiration. Respiration occurs when animals take in oxygen from the air along with simple sugars from their food. This helps in the release of carbon dioxide, water, and energy from the animal body. During cellular respiration, animals require O2 while inhalation. When they exhale the waste product of cellular respiration, they release CO2 into the atmosphere again.

Formula for Respiration

(CH2O) + O2 ———-> CO2 + H2O + Energy

The carbohydrates taken from food like plants or carbon-based compounds along with oxygen are converted to carbon dioxide which is released into the air along with water and energy during respiration.

Combustion

It is a process of burning that occurs naturally in nature. For example, volcanic eruptions are natural combustion processes where carbon dioxide is released into the atmosphere due to burning. Nowadays, many environmental pollutants cause an increase in the amount of CO2 in the air. These include cars, factories, burning of woods, coal, nuclear energy, gas, etc. This irresponsible combustion and release of excessive carbon dioxide and other harmful gases in the environment is the major contributing factor to today’s global warming.

Decomposition

After the death of any living organism, i.e., unicellular or multicellular organism, it gets decomposed. This decomposition means insects, fungi, and bacteria (together called decomposers), help in breaking down the cellular components of the dead organism into its basic elements. These elements include water, calcium, nitrogen, carbon, and oxygen. Thus, decomposers help in the release of oxygen and carbon dioxide back into the atmosphere as their metabolic waste products.

The entire cycle can be summarized as, plants taking in carbon dioxide and releasing oxygen during photosynthesis. This oxygen released is taken up by animals who release carbon dioxide after carrying out respiration. Thus, the recycling of carbon and oxygen in the atmosphere will continue as long as respiration and photosynthesis occur. This also proves that to sustain life, plants are very important as they are the major contributors to the amount of oxygen present in the atmosphere. Although both cycles occur independently, they are, in a small way, interconnected to each other.

The different processes where carbon and oxygen will combine and help in different biological process are combustion, photosynthesis and respiration.

A biological process is the organism's genetically designed means of achieving a particular goal. The outcome or final state of biological processes is frequently used to characterize them, for example, the biological process of cell division produces two daughter cells (a divided cell) from a single parent cell.

A biological process is carried out by a specific collection of molecular operations performed by certain gene products (or macromolecular complexes), frequently in a highly controlled manner and in a specified temporal sequence. Oxygen and carbon used in many biological process such as photosynthesis.

Therefore, The different processes where carbon and oxygen will combine and help in different biological process are combustion, photosynthesis and respiration.

The organic materials that remain after photosynthesis organisms in the ecosystem have used some of these compounds for their cellular energy needs called primary productivity.

Cellular respiration is defined as the process  through which organisms combine oxygen with food molecules, converting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, water and carbon dioxide.

Common examples of primary producers include diatoms,  coccolithophores and dinoflagellates.

Human activities such as burning of fossil fuels is the main cause of acidic pH of the ocean.

The pH of the ocean tends to increase because of human activities that increased levels of carbon dioxide in the atmosphere. This CO2 is dissolved into the ocean and makes the ocean more acidic.

Variable of climate (x) and biodiversity (y) would be added to evaluate the role of human activity in the pH of the ocean.

So we can conclude that human activities such as burning of fossil fuels is the main cause of acidic pH of the ocean.

Sulfur is especially important for chemotrophs living near deep volcanic thermal vents in the ocean. Therefore, option C is correct.

An organism is said to be a chemotroph if it uses the environment's electron donors to oxidize them for energy. They might be organic or inorganic molecules. In contrast to phototrophs, which use photons, chemotrophs employ chemicals. Both autotrophic and heterotrophic chemotrophs are possible.

Prokaryotic chemotrophic organisms, which comprise both bacteria and fungi, are the most prevalent type. For all of these species to exist and procreate, carbon is necessary.
