HORTICULTURE

Detailed explanation-1: -The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic (auto = self; trophos = nourishment) nutrition. Therefore, plants are called autotrophs. Animals and most other organisms take in food prepared by plants. They are called heterotrophs (heteros = other).

Detailed explanation-2: -The mode of autotrophic nutrition which takes place in the presence of sunlight is called photoautotrophic nutrition or photosynthesis. The green plants are photoautotrophs as produce their own food is called photosynthesis.

Detailed explanation-3: -The mode of nutrition in which organisms make their own food from simple substances is called autotrophic nutrition(auto = self; trophos = nourishment). Plants are called autotrophs. They make their food with carbon dioxide and water in the presence of sunlight.

Detailed explanation-4: -Autotrophic nutrition is the type of nutrition where organisms synthesize their own food. They are called producers in the ecosystem. They use sunlight, water, and carbon dioxide to synthesize food. Autotrophic nutrition is of two types such as photoautotrophs and chemoautotrophs.
