(2) Micronutrients:
Micronutrients are crucial substances for the residing organisms that are required in small quantity for the upkeep of the physique, Any such vitamins performs an excellent position within the development and growth of residing organisms. The shortage of micronutrients can result in numerous ailments to the organisms.
1. Autotrophic Diet:
It's a course of by which inexperienced crops and a few micro organism can produce their very own meals from easy inorganic substances like water, mineral salts and carbon dioxide by the method of photosynthesis utilizing photo voltaic vitality.
2. Heterotrophic Diet:
Non-autotrophic organisms rely on autotrophic organisms for his or her meals which is called heterotrophs. Heterotrophs are animal and non-photosynthetic crops which can't produce their very own meals. Diet exhibited by heterotrophs is called heterotrophic vitamin

Significance of Nutrition
1. Nutrition performs an necessary position within the manufacturing of warmth within the animal physique.
2. It meets the caloric demand of residing organisms.
3. Diet develops the illness resistance energy of the residing physique.
4. It controls the totally different metabolic features of the residing physique.
5. It supplies vitality which helps for development and repairing of tissue.
6. It helps to retailer future meals issues inside the residing physique.
7. It helps to retailer potential vitality and remodel into usable vitality inside the residing physique.
8. It controls totally different physiological features of the residing physique like motion, locomotion, excretion, copy and so on
