Most plants are autotrophs because they make their own food. Some plant species are parasitic, meaning they get their nutrients from other sources. Parasitic plants are heterotrophic.
Any plant with green leaves is classified as an autotroph. The definition covers trees, mosses and flowering plants, to name a few. Most plants use photosynthesis to produce food in the form of sugar.
Plants are not the only organisms classified as autotrophs, although they are one of the most well-known examples. Phytoplankton, algae and some types of bacteria are also able to make their own food. Some of these organisms use chemosynthesis instead of photosynthesis.
Chemosynthesis uses the energy generated by chemical reactions to produce food. Some of the bacteria that live in the ocean use hydrogen sulfide to power chemosynthesis.
Parasitic plants are unable to make their own food. These plants feed off the roots or stems of their hosts.Learn More
Living rocks, known as lithops, are autotrophs. Examples of autotrophs include plants, algae and some types of bacteria. Autotrophs use sunlight, water and carbon dioxide to form sugar, which they use in cellular respiration. The conversion of sunlight, water and carbon dioxide into sugar is known as photosynthesis.Full Answer >
The Plantae kingdom is the only kingdom that is entirely autotrophic; Eubacteria, Protista and Archeabacteria contain some autotrophs. Kingdoms Fungi and Animalia are solely heterotrophic. Living things that are autotrophic can make their own energy, while heterotrophic organisms must look to other organisms for food to use as energy.Full Answer >
Caribou moss, like other Arctic lichens, can make its own food, has strong and hardy tissues, and can survive for long periods of time without water. Caribou moss belongs to the class of lichens. These hardy species have unique adaptations, like many Arctic-dwelling organisms, to endure tough winters and survive in extreme conditions.Full Answer >
Chlorophyll is a green pigment found in plants and cyanobacteria, which are bacterial organisms that make their own food. This pigment absorbs light energy for use in photosynthesis.Full Answer >
