Hint: All the organisms that produce energy by photosynthesis are called producers. They occupy the first trophic level in the grazing food chain(GFC).
Complete answer:
The Energy passes from one trophic level to another trophic level in the food chain, mostly flowing from a lower trophic level to higher trophic levels. Producers are present in the first trophic level of the food chain. Plants and organisms like algae which contain chlorophyll synthesize carbohydrates by the process called photosynthesis. They are considered as producers in the food chain.
Additional Information:
- An organism may occupy more than one trophic based upon its food habits.
- The number of trophic levels in the food chain varies from three to five.
- The biological system present in the environment that includes various food chain levels are called trophic levels.
- There are five trophic levels namely the first second third fourth and fifth trophic levels.
- Green plants occupy the first trophic level herbivores occupy the second trophic level and carnivores occupy the third, fourth, and fifth trophic levels.
- Food chains in the ecosystem is mainly divided into three types namely the Grazing food chain, Parasitic food chain, and detritus food chain.
-Grazing food chain includes green plants that come under the first trophic level and second, third, fourth, and fifth trophic levels are occupied by herbivores, primary carnivores, secondary carnivores, and tertiary carnivores respectively.
- In parasitic food chain food energy passes from large organisms to small organisms.
- Detritus food chain consists of organisms that depend on dead and decaying matter for energy called decomposers.
So, the correct answer is ‘primary producers’
Note: The grazing food chain is also known as the predatory food chain.
Decomposers present in the detritus food chain are also known as saprotrophs which are heterotrophic organisms.
The Detritus food chain is connected to the grazing food chain at some levels.
