differentiate between photosynthetic autotrophs and chemosynthetic autotrophs

A-photosynthetic autotrophs use Co2 as a carbon source. There are two major autotrophic methods of nutrition: photosynthetic and chemosynthetic. Phototrophs and chemotrophs are two types of nutritional groups found in the environment. Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition. Explain about the similarities and differences between chemosynthesis and photosynthesis. Autotrophs: Autotrophs are organisms that have the ability to make their own food. The main difference between autotrophic organisms and heterotrophic organisms is that the former produce their own food, while the latter rely on other organisms for food. Chemosynthesis is the process in which chemical energy is used to synthesize carbohydrates. Main Difference – Phototrophs vs Chemotrophs. The key difference between the phototrophs and heterotrophs is the energy source that they use. C-chemosynthetic autotrophs obtain energy from inorganic compounds. Autotrophs produce their own food from simple inorganic substances when an energy source is available. Examples for chemosynthetic autotrophs are Nitrosomonas, Beggiatoa. Phototrophs rely on sunlight to obtain energy while chemotrophs do not rely on sunlight to obtain energy instead rely on chemicals for energy production. Describe the differences between autotrophs and heterotrophs. B. Autotrophic Bacteria (Autotrophs): They synthesize their own organic food from inorganic substances (CO 2 and hydrogen donor) Autotrophic bacteria are of two types: (i) photoautotrophic (photosynthetic) which make use of light energy and (ii) chemoautotrophic (chemosynthetic) which … but in photosynthesis, light energy is converted into chemical energy and stored in … Key Differences between Heterotrophs and Autotroph. During this, energy is released and used for its growth. Beggiatoa oxidises H2S to sulphur and water. Nitrosomonas oxidizes ammonia into nitrite. Heterotrophs eat other organism to get food and energy whereas autotrophs synthesize their own food and energy; Heterotrophs do not store energy whereas autotrophs store energy in the cells in the form of ATP. The energy liberated during this process is used for the synthesis of carbohydrates. B-chemosynthetic autotrophs use Co2 as a carbon source. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Autotrophs create nutritional organic substances from simple inorganic sources like carbon dioxide. Heterotrophs cannot produce organic compounds from inorganic substances. Most phototrophs are autotrophs, using the energy from sunlight to produce their food.Chemotrophs oxidize inorganic compounds or organic compounds as their energy source. They perform photosynthesis as well as chemosynthesis. D-photosynthetic autotrophs synthesize organic compounds. Chemosynthetic and photosynthetic autotrophs are two types of autotrophs. The former take advantage of the water and energy of sunlight to break the molecule of carbon dioxide (CO 2 ) from the surrounding air and thus obtain energy. • Autotrophs- Self-Feeding Two kinds Photosynthetic use light and chemosynthetic autotrophs that use inorganic chemical reactions.
