Chemosynthesis reaction

The energy comes from the oxidization of inorganic chemicals that the organisms find in their environment. The process occurs in many bacteria, and in another group of organisms known as archaea. The life forms that use this method to obtain energy are found in a variety of environments, including soil, the intestines of mammals, petroleum deposits, and in extreme conditions, such as around hydrothermal vents on the ocean floor. They are adapted to circumstances which may have been commonplace billions of years ago, leading some scientists to theorize that they may be direct descendants of the earliest life on Earth.

Chemosynthesis reaction

Photosynthesis - Wikipedia

As fuel for life What is Photosynthesis? Ecosystem depends upon the ability of organisms to convert inorganic compounds into food that other organisms use as fuel for their lives. Photosynthesis is a primary food production which is powered by solar energy.

Plants and microbes cannot eat food, so they have to make food for themselves. Photosynthesis takes place in plants and some bacteria, where there is sufficient sunlight. This occurs on land, shallow water and sometimes below ice where sunlight can reach.

Photosynthetic organisms species and plants convert carbon dioxide and water into sugar and oxygen by using sun light. Following formula is a description of this reaction: The water is then transferred to the leaves by particular cells of plants called xylem.

Plants consume some water when other natural processes occur, and some water is used during the photosynthesis process. Plants have special cells called stomata which open and close on stimulus.

Chemosynthesis reaction

Plants take carbon dioxide through the stomata and release oxygen formed during the chemical reaction of photosynthesis.

Plants also lose some water during this gas exchange. Chlorophyll is a complex molecule which is present in green plants and absorb light.

Any substance which absorbs light is called pigment. Pigments absorb light of a specific wavelength and reflect the rest back. Chlorophyll absorbs all wavelength of light except for green.

Because of this reason, grass and leaves of trees look green. When a plant absorbs light energy or carbon dioxide, chlorophyll causes the chemical reaction which turns the light into two different substances; ATP and NADPH.

These two substances are both unstable forms of energy which the plant then uses for other reactions. During a chemical reaction, water molecule gets splits and release oxygen into the air. Advertisement What is Chemosynthesis?

Chemosynthesis is another process which provides fuel to live on earth. In some environments, primary production of fuel occurs through chemosynthesis a nutrition characteristic which runs on chemical energy.

Chemosynthesis is a process of use of energy produced by inorganic chemical reactions to produce food. This process occurs in the heart of deep sea communities, sustaining life in the absolute darkness where the light of the sun does not penetrate.

All organisms doing chemosynthesis use the energy released by chemical reactions to make sugar. Different species use different pathways for chemosynthesis. For example, undersea hot springs are the most extensive ecosystem which based on chemosynthesis.

At these hydrothermal vents, bacteria oxidize hydrogen sulfide, add carbon dioxide and oxygen and produce water, sulfur, and sugar.

Other bacteria produce sugar matter by reducing sulfide or oxidizing methane. Chemosynthetic bacteria are present in hot springs on land and on the seafloor around hydrothermal vents, whale carcasses, cold seeps and sunken ships.

Hydrogen bacteria are most numerous group of chemosynthetic bacteria. Advertisement Both photosynthesis and chemosynthesis need carbon dioxide as fuel for the process to produce carbohydrates. Both processes result in energy source for the organisms. Photosynthesis occurs only in green plants or in organisms which have chlorophyll while chemosynthesis occurs only in bacteria.

Photosynthesis needs sun energy as an essential requirement while chemosynthesis does not need solar energy for the process.Chemosynthesis is the conversion of carbon compounds and other molecules into organic this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source.

In contrast, the energy source for photosynthesis (the set of reactions through which carbon dioxide and water are converted into glucose and oxygen.

Chemosynthesis Definition

When a chemical reaction occurs, it can be described by an equation. This shows the chemicals that react (called the reactants) on the left-hand side, and the chemicals that they produce (called the products) on the right-hand side.

The chemicals can be represented by . Chemosynthesis is the conversion of inorganic carbon-containing compounds into organic matter such as sugars and amino acids.

Chemosynthesis uses energy from inorganic chemicals to perform this task. Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food. Chemosynthesis is at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate.

Calcification A dry environment soil-forming process that results in the accumulation of calcium carbonate in surface soil layers.

Calcite Mineral formed from calcium mineral found in limestone. Calcium Carbonate. Chemosynthesis vs. Photosynthesis Ecosystems depend upon the ability of some organisms to convert inorganic compounds into food that other organisms can then exploit.

In most cases, primary food production occurs in a process called photosynthesis, which is powered by sunlight.
