Nutrition in animals

Nutrition is a mode of taking food by an organism.

Their are two modes of nutrition. 1) Autotrophic mode of nutrition 2)Heterotrophic mode of nutrition.
 * Autotrophic mode of nutrition : The mode of nutrition in which organism is not dependent on other organisms for their food.they prepare their own food. the organisms which have autotrophic nutrition are called as autotrophs.examples - plants
 * Heterotrophic mode of nutrition : The mode of nutrition in which organisms take ready made food from other organisms. the organisms which have heterotrophic mode of nutrition are called as heterotrophs.exaples of hetroptophs are animals,human beings.

Nutrition in plants .

Plants are having autotrophic mode of nutrition so they are called autographs. is it not interesting that how plants can prepare their own food.what makes plants so special that they can prepare their own food but not animals. we will get all answers after reading the below content. []
 * The food making process in plants is called as photosynthesis.
 * Plants take up water & minerals by roots, take carbon dioxide from atmosphere through tiny pores present on leaves called as stomata.
 * The green pigment present in leaves called as chlorophyll absorbs sunlight. plants by using water minerals, carbon dioxide in the presence of sunlight produces glucose & oxygen this process is known as photosynthesis. it is named as photosynthesis because it is taking place in the presence of sunlight.
 * The glucose produced will be used up by plants & remaining glucose is stored as starch in plants.
 * The oxygen produced is released in to atmosphere by stomata. the oxygen is used by all animals for respiration.so this is the reason why we need to save plants because plants are very important for maintaining ecological balance.
