Decrease
In a food chain, the energy transferred from one organism to another will decrease.
In a food chain, the energy transferred from one organism to another will decrease. This is known as the 10% rule. The reason for this is that energy is lost at each trophic level as organisms respire, excrete waste, and use energy for their own metabolic processes.
To understand why the energy decreases, let's take an example of a simple food chain: grass (producer) -> grasshopper (primary consumer) -> frog (secondary consumer) -> snake (tertiary consumer).
When a grasshopper eats grass, it gains a certain amount of energy from the grass. However, the grasshopper does not utilize all of this energy for its own growth and functions. Some of it is lost as heat through respiration and some is used for movement. As a result, only a fraction of the energy is passed on to the frog when it eats the grasshopper.
Similarly, when the frog eats the grasshopper, it also loses energy through various metabolic processes, and only a fraction of the energy is transferred to the snake if the snake feeds on the frog.
This process repeats at each trophic level, and each time, only around 10% of the energy is transferred to the next level. This is because organisms need energy to survive, grow, and reproduce, and they use a significant portion of it for their own needs.
Therefore, in a food chain, the energy transferred from one organism to another gradually decreases, leading to a decrease in available energy as you move up the trophic levels.
