Each step or level of a food chain forms a trophic level. Which of the following is at the first trophic level of the said food chain?

The correct answer is Autotrophs or the producers. 

Key Points

• The first trophic level of the said food chain is Autotrophs or the producers.
• A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat.
• A food chain shows how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposes such as fungi.

Additional Information

• Based on the source of their nutrition or food, organisms occupy a specific place in the food chain that is known as their trophic level.
• Producers belong to the first trophic level, herbivores (primary consumer) to the second and carnivores (secondary consumer) to the third. The important point to note is that the amount of energy decreases at successive trophic levels.
