Question

what are the necessary conditions for autotrophic nutrition and why are its by products

Answer 1

Answer:

Autotrophic nutrition takes place through the process of photosynthesis. Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.

Answer 2

Conditions necessary for autotrophic nutrition;

• Autotrophic nutrition is the mode of nutrition where the organism prepares its own food.
• There are two types of autotrophic nutrition; Photo-autotrophic nutrition which requires sunlight and chemo-autotrophic nutrition which does not require sunlight.
• Photo-autotrophic nutrition occurs through the process of photosynthesis.
• Sunlight, carbon dioxide, water, and chlorophyll are the conditions necessary for photo-autotrophic nutrition.
• Chemo-synthetic autotrophs produce chemical energy by oxidizing inorganic compounds like methane, hydrogen, ammonia, nitrite, etc.
• Since they lack chlorophyll, they rely on carbon-containing compounds like carbon dioxide, methane, hydrogen sulfide, etc.
• Chemical energy and carbon sources are the necessary conditions for chemo-autotrophic nutrition.

By-products of autotrophic nutrition;

• In photo-synthetic autotrophs, glucose and oxygen are the by-products.
• In chemo-synthetic autotrophs, proteins, carbohydrates, etc. are the by-products.
