Food chains. ... The other organisms in the food chain are consumers – they all get their energy and biomass by consuming (eating) other organisms. Most food chains are quite short, and they rarely consist of more than four steps. This is because a lot of energy is lost at each step.

i can also copy it from Google
so wait please
as you wish
All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level
The trophic level of an organism is the number of steps it is from the start of the chain. A food chain starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.
