What is the difference between the food habits of organisms belonging to the first and the third trophic levels? Give one example each of the organisms belonging to these two trophic levels.
The organisms belonging to the first trophic level are producers which make their own food with the help of the sun’s energy.
Example – Green plants.
The organisms of the third trophic level are carnivores that feed upon herbivores.
Example – Lion and Tiger.
