Nutrition is the way living organisms obtain food for energy and growth. It is mainly of two types – autotrophic and heterotrophic. In autotrophic nutrition, organisms make their own food. In heterotrophic nutrition, organisms depend on others for food. The Difference between Autotrophic and Heterotrophic Nutrition is discussed in detail below in this article.<\/span><\/p>\n

Difference Between Autotrophic and Heterotrophic Nutrition<\/b><\/h2>\n

Nutrition is mainly of two types – autotrophic and heterotrophic, based on how organisms obtain their food. The Difference between Autotrophic and heterotrophic nutrition is discussed below<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\n

Meaning<\/b><\/p>\n<\/td>\n

\n

Organisms make their own food.<\/span><\/p>\n<\/td>\n

\n

Organisms cannot make their own food.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Dependence<\/b><\/p>\n<\/td>\n

\n

They are independent for food.<\/span><\/p>\n<\/td>\n

\n

They depend on other organisms for food.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Food Preparation<\/b><\/p>\n<\/td>\n

\n

Food is prepared from carbon dioxide and water using sunlight (photosynthesis) or chemical energy.<\/span><\/p>\n<\/td>\n

\n

No photosynthesis takes place; food is obtained from plants or animals.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Role in Food Chain<\/b><\/p>\n<\/td>\n

\n

Called producers; they form the first trophic level.<\/span><\/p>\n<\/td>\n

\n

Called consumers; they occupy higher trophic levels.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Type of Substances Used<\/b><\/p>\n<\/td>\n

\n

Convert simple inorganic substances into complex organic food.<\/span><\/p>\n<\/td>\n

\n

Consume complex organic food and break it into simpler substances during digestion.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Energy Source<\/b><\/p>\n<\/td>\n

\n

Get energy from sunlight or chemical reactions.<\/span><\/p>\n<\/td>\n

\n

Get energy directly or indirectly from autotrophs.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Presence of Chlorophyll<\/b><\/p>\n<\/td>\n

\n

Usually contain chlorophyll for photosynthesis (in plants).<\/span><\/p>\n<\/td>\n

\n

They lack chlorophyll and cannot perform photosynthesis.<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Movement<\/b><\/p>\n<\/td>\n

\n

Most autotrophs (like plants) are non-motile.<\/span><\/p>\n<\/td>\n

\n

Many can move in search of food (e.g., animals).<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

Examples<\/b><\/p>\n<\/td>\n

\n

Green plants, algae, some bacteria.<\/span><\/p>\n<\/td>\n

\n

Humans, cows, lions, fungi, most animals.<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

About Autotrophic Nutrition<\/b><\/h2>\n

Autotrophic nutrition is a type of nutrition in which organisms prepare their own food from simple inorganic substances like carbon dioxide and water. They use energy from sunlight or chemical reactions to make organic food. Organisms that follow this mode of nutrition are called autotrophs. They do not depend on other living beings for food and are therefore known as <\/span>producers<\/b> in an ecosystem.<\/span><\/p>\n

Process of Food Production<\/b><\/h3>\n

Autotrophs make food mainly by two processes:<\/b><\/p>\n
