hiiii mate
A food chain is a diagram that shows us how animals are linked by what they eat; in food webs we represent the links between animals who eat or are eaten by more than one kind of animal.
The trophic level of an organism is the place it has in a food chain. A food chain is mostly made up of three trophic levels. However, some trophic levels have four trophic levels. An example is shown in the diagram.
→Primary producers which are plants that are autotrophs and belong to the first trophic level.
→Primary consumers are animals that belong to second trophic level and feed on plants. They are called herbivores.
→Secondary consumers feed on herbivores and belong to the third trophic level. They are called primary carnivores.
→Tertiary consumers feed on primary carnivores and belong to the fourth trophic level. They are called secondary carnivores.

Explanation:
the transfer of food or energy takes place various steps or level in the food chain known as trophical levels. the producers (autotrophs)are the parents at the first trophical level. they fix solar energy, making it available for consumers (hetertrophs). the herbivores or the primary consumers are found at the second trophical level. small carnivorous or secondary consumers are the present at the third trophic level. the large or the teritatry consumers from the fourth trophical level.
