Autotrophic Nutrition
Autotrophs synthesize organic materials from inorganic materials. Some organisms derive their energy for this process from sunlight and are called photoautotrophs. Example: Green plants Other organisms use chemical energy and are called chemoautotrophs. Exam..
Autotrophic Nutrition
'Auto' means self and 'trophic' refers to food. So, the organisms which synthesise their own food are called the autotrophs and the process is called autotrophic nutrition. Autotrophs include all green plants and some bacteria such as the..

Types of Heterotrophic Nutrition - Holozoic Nutrition
This type of nutrition involves the taking in of solid particles of food which have to be further broken down into simpler particles inside the organism (there are exceptions which are called fluid feeders. Think of at least two of them. Look for answers in the Q & A section). These ..
Nutrition in Plants
Most plants are autotrophic. They synthesize their own food. The green plants, also called the producers, trap the solar energy and convert it into chemical energy of the food. The biochemical reactions in the body which result in the formation of chemi..
