The energy comes from the oxidization of inorganic chemicals that the organisms find in their environment.
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 Does chemosynthesis release oxygen 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.
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.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.
The process does not involve carbon dioxide fixation and does not release oxygen, and seems to have evolved separately from the more common types of photosynthesis.
 . Chemosynthesis in the deep-sea: life without the sun C. Smith Howarth and Smith, West 6th St.
Suite Los Angeles, CA, USA 10 chemosynthesis makes use of oxygen as the primary electron acceptor, ment of tectonic plates are responsible for the release of . Photosynthesis also needs oxygen for the process while chemosynthesis does not need oxygen for the process. Water is used during the process of photosynthesis while water is produced as the end product in chemosynthesis.
Photosynthesis is a chemical process that occurs in many forms of bacteria and virtually all plants, including aquatic plants and algae. Using just three simple ingredients (carbon dioxide, water, and sunlight) plants and bacteria are able to make their own food.
As long as photosynthesis is occurring, oxygen is continuously being released into the air and into the world's lakes, oceans, rivers, and ponds. Photosynthesis by algae, bacteria, and plants provides the air that humans breathe. The Basics of Photosynthesis.
