why do most of the food chains consist of four steps
Answers
Answer:
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.
Explanation:
The food chain consists of four main parts:
The Sun, which provides the energy for everything on the planet (except organisms living near the hydrothermal vents).
Producers: these include all green plants. ...
Consumers: In short, consumers are every organism that eats something else.
A food chain’s length is restricted to just 3 or 4 steps due to energy loss. Moreover, the energy added to the biomass of each trophic level is significantly lower than the one preceding it. This occurs as a result of material wastage from subsequently trophic levels and for the maintenance of various life processes. Consequently, the shorter the food chain, the more energy that is available to the final consumer. A shorter food chain is also considerably more efficient as less energy is lost.
