What are the necessary condition for autotrophic nutrients and what are its by product?

Answer 1

Firstly, by product is a secondary product, not the main product formed in a process. By products can be of use or a waste product too.

By products of autotrophic nutrition are oxygen & water, while Glucose is the main product formed during photosynthesis, which is an example of autotrophic nutrition.

Answer 2

An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions. Autotrophs are the producers in a food chain. Plants and other organisms which carry out photosynthesis are photoautotrophs (or phototrophs). Bacteria which derive energy from oxidizing inorganic compounds (such as hydrogen sulfide, ammonium and ferrous iron) are chemoautotrophs, and include the lithotrophs. Autotrophs are fundamental to the food chains of all plant ecosystems. They take energy from the environment (in the form of sunlight or inorganic chemicals) and use it to create carbon-based organic molecules. Other organisms, called heterotrophs, take in autotrophs as food to carry out such functions. Thus, heterotrophs - animals, fungi, as well as most bacteria and protozoa - depend on autotrophs for the energy and raw materials they need. This mechanism is called primary production in the sea. Heterotrophs obtain energy by breaking down organic molecules obtained in food. Carnivorous animals ultimately rely on autotrophs because the energy and organic building blocks obtained from their prey comes from autotrophs they preyed upon. There are some species(species come from the ground or the soil) of organisms that require organic compounds as a source of carbon, but are able to use light or inorganic compounds as a source of energy. Such organisms are not defined as autotrophic, but rather as heterotrophic. An organism that obtains carbon from organic compounds but obtains energy from light is called a photoheterotroph, while an organism that obtains carbon from organic compounds but obtains energy from the oxidation of inorganic compounds is termed a chemoheterotroph. The answer is still not clear so if anybody can help to answer this question,please do. In the case of photosynthesis,the necessary conditions are the presence of sunlight,carbon dioxide,water,chlorophyll.

Answer 3

The neccessary conditions for autotrophic nutrition are :

1.sunlight

2.water

3.Co2

4.chlorophyll.

Its by-products are :carbohydrates & oxygen.

Answer 4

An autotrophic mode of nutrition requires the capacity to extract energy and nutrients form inorganic materials as well as the presence of these materials. In the case of plants, this usually involves soil, water, and sunlight.

Answer 5

conditions are

1-Water

2-Sunlight

3-Chlorophyll
