Heterotroph - Wikipedia
The difference between an autotroph vs. heterotroph lies in the There are some heterotrophs and autotrophs that have formed symbiotic relationships because of this necessity. Archaebacteria: Definition And Examples. Autotrophs and Heterotrophs. Organisms are divided into autotrophs and heterotrophs according to their energy pathways. Autotrophs are those organisms that. Autotrophs and heterotrophs are two main categories of living organisms. Autotrophs are able to extract raw carbon from the atmosphere and turn it into energy-rich compounds; Correlation What are Autotrophs?.
Learn about the flow of energy through the food chain in this lesson on autotrophs and heterotrophs. Food Chain How do you obtain energy? Well, you probably know that you obtain your energy from the food you eat, but what about plants? How do they obtain energy? Unlike us, plants can use the sunlight to make their own food!
And this is one of the main things that separates plants from animals. The way an organism obtains energy places it into one of two categories, autotrophs or heterotrophs, or those that can make their own food vs. Both of these groups are important in our ecosystems. Without autotrophs, heterotrophs wouldn't have any food sources. Let's take a look at a food chain: Example of a food chain A food chain shows how energy flows from producers autotrophs to consumers heterotrophs to decomposers, who break down the energy so that it can be reused.

Autotrophs At the base of the food chain are autotrophs. In fact, they do not need to move from one place to other in search of food. Hence from the above reaction, we can say that they convert light energy into chemical energy.
Some autotrophs use another process called as chemosynthesis, in this, they use energy from chemical reactions to make food rather from obtaining it from the sun.
Organisms living in extreme environments like bacteria living in active volcanoes, or in deep ocean use this process. Pitcher plants are the exception as they are categorized as mixotrophic, as they obtain their nutrition from plants as well as by eating insects also.
Autotrophs and Heterotrophs
Key Differences Between Heterotrophs and Autotrophs Given below are the substantial difference between heterotrophs and autotrophs, on the basis of their mode of nutrition, their dependency, their process of obtaining food, etc. Animals like cow, dog, elephant, rhino, lion, etc.
Heterotrophs are considered as consumers and are placed at a secondary or tertiary level in the food web, while autotrophs are primary producers. Heterotrophs do not contain chloroplast, chlorophyll and hence are unable to prepare their own food, also depend on other for obtaining energy.
Autotrophs contain chloroplast, chlorophyll and hence are able to produce their own food and depends on sunlight, air, and water for the preparation of food.

- Difference Between Heterotrophs and Autotrophs
Autotrophs Autotrophs make their own food. Typically, we think of plants as autotrophs, and this is true, but there are other kinds as well. Plants, algae, phytoplankton, and some bacteria are photosynthetic, meaning they use sunlight to make sugar, which they then use to make energy. Photosynthetic organisms are green because they contain a pigment called chlorophyll that does photosynthesis. Some other types of bacteria are also autotrophic, but they are chemosynthetic.
They use the energy stored in chemicals, usually released from deep sea vents, to make their food, and then energy. Green leaves make food through photosynthesis Autotrophs form the basis of all food webs. They gather energy from inorganic sources, like chemicals or the sun, and convert it into a form that other animals can use. Energy is transferred from the autotrophs to consumers that eat them, and then to carnivores that eat those animals.
Without autotrophs, all of our food webs would collapse. Since there is so much energy available to this layer of the food web, autotrophs have the greatest number of organisms in an ecosystem. Think of how many blades of grass there are in a field compared to how many bears you typically see. Autotrophs also have an easier time finding a suitable environment.
