because the producer is the main part of it and then lets say planton eats it then and worm will eat the planton a bird will eat the worm and so on
food/energy
Each level in a food chain contains less energy because energy is lost as heat through metabolic processes like respiration and digestion as it moves up the chain. This means that less energy is available for transfer to the next level.
Each trophic level has about 10% less energy available than the level below it. This is due to energy being lost as heat during metabolic processes and as it moves up the food chain.

It decreases because there are less and less animals as you go up.
At each trophic level in a food chain, a large portion of the energy is utilized for the maintenance of organisms which occur at that trophic level and lost as heat. As a result of this, organisms in each trophic level pass on less and less energy to the next trophic levels, than they receive.
Energy is lost as it moves up the food chain through processes like respiration, heat loss, and waste production, resulting in less energy available for each successive organism at higher trophic levels. This leads to a decrease in the number of organisms at each feeding level, as it becomes less efficient to support larger populations due to the decreasing available energy.
An energy pyramid represents the amount of energy available at each level of a food web. It shows how energy is transferred between trophic levels, with each level containing less energy than the one below it. This is due to the loss of energy as heat through respiration and other metabolic processes.
Energy pyramids are graphical representations of the flow of energy within an ecosystem. They show how energy is transferred from one trophic level to another, with each level representing a different position in the food chain. Typically, energy pyramids show that energy is lost as heat at each trophic level, resulting in less energy being available at higher levels.
Because there is less energy available at each feeding level, there is a limit to how many organisms can be a part of each progressive level.
Energy pyramids are always slopping because less energy is transferred from each level than was paid into it. The plants and other green organisms produce the food for the web. But they need to use some of the energy for growth and for reproduction (90%).That leaves about 10% for the next level. That level also needs energy for growth and reproduction, so that leaves 10% of that first 10% for the third level.Since this works this way, each level is smaller and smaller. The number of species at each level competes for food with the others in that level.
The mutual force of gravitation drawing two objects toward each other is less when the product of the masses is less or when they're farther apart.
