Hey mate..

Let's go towards the brief journey of energy-flow in a food chain:---

The flow of energy between various components of the food chain has been extensively studied and it has been found that:--
▪The green plants in a terrestrial ecosystem capture about 1% of the energy of sunlight that falls into them and convert them into food energy.
▪ When green plants are eaten by primary consumers , a great deal of energy is lost as heat to the enviroment , some amount goes into the digestion, and in doing work and the rest goes towards growth and reproduction.An average of 10% of the food eaten is tyrned into its own body and reaches the next level of consumers.
▪Therefore, 10% can be taken as the average value for the amount of organic matter that is present in each step and reaches the next level of consumers.
▪Since, so little energy is available for the next level of consumers, the food chain consists of three to four steps. The loss of energy at each step is so great that only a very little usable energy remains after four trophic levels.
▪There are generally a larger number of individuals in the lower level of food chain. The highest number is of the producers.
▪The length and complexity of the food chains vary greatly. Each organism is generally eaten by two or more other kinds of organisms which in turn are eaten by several other organisms. So, instead of having a straight line food chain the relationship can be shown as a series of branching lines called food web.
