whAT ARE photosynthetic and chemosynthetic autotrophes???? givee detail..
Autotrophic organisms are those organisms that can prepare their own food themselves. They are of two types : Photosynthetic and chemosynthetic autotrophs
Photosynthetic autotrophs are those organisms that can prepare complex organic food from inorganic nutrients by entrapping solar energy in the presence of pigments such as chlorophyll found in green plants and cyanobacteria ( blue green algae) , bacteriochlorophyll and bacterioviridin found in green and sulphur bacteria .
Chemosynthetic autotrophs oxidize various inorganic substances such as nitrites, nitrates, ammonia, etc in order to get energy without utilising solar energy. They play key role in recycling nutrients such as nitrogen, sulphur, iron, etc. For example: Nitrifying bacteria suchas Nitrosomonas and Nitrobacter
