Approximately only 10% of the energy from one tier of the food chain goes to the animal from the one above. This is because the prey uses the other 90% for maintaining heat, being able to move, reproduction, and digestion. This means that the predator has to eat a large amount of the prey to get the necessary amount of energy so they can do them processes. Consequently, as you get further up the food chain, there are less numbers of predators, as the prey cannot provide enough energy to sustain a large amount of predators. This is also why you will rarely find more than two predators in a particular food chain, e.g oak tree-aphid-blackbird-fox. this is because the amount of energy that a third predator would need to survive is implausible to be able to get it from the amount of food it would get from the foxes.
Energy and biomass decrease as you move up the food chain due to the second law of thermodynamics, which states that energy is lost as it moves through trophic levels. Organisms higher up in the food chain have less energy available to them compared to those lower down.
The energy stored in food is lost as heat during metabolism, movement, and other activities by the organism. This limits the amount of energy that can be passed on to the next organism in the food chain. As a result, only about 10% of the energy is transferred to the next trophic level, leading to a decrease in available energy as you move up the food chain.
The greatest amount of energy in an ecosystem is available to producers, such as plants, that convert sunlight into chemical energy through photosynthesis. This energy then flows through the food chain to primary consumers, such as herbivores, and subsequent trophic levels. Each level utilizes some energy for processes like metabolism and growth, resulting in a decrease in available energy as it moves up the food chain.
Biomass is defined as any biological material from living or recently living organisms. Since every living organism is a part of the food chain, less energy becomes available the more it climbs up the chain, resulting in a decrease in biomass.
As trophic levels increase, the biomass of organisms generally decreases. This is because energy is lost as it moves up the food chain through trophic levels, with only a portion transferred to higher-level consumers. Consequently, the biomass available to support organisms at higher trophic levels is reduced.
It decreases by 90% and only 10% goes on
Energy and biomass decrease as you move up the food chain due to the second law of thermodynamics, which states that energy is lost as it moves through trophic levels. Organisms higher up in the food chain have less energy available to them compared to those lower down.
Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
Every step of energy transformation have loss. Progress through the energy chain, the amount of energy transferred would unavoidably degraded. So as the chain progress it get narrower to a pyramid shape.
an energy pyramid
The hawk, depending on where it Is in the food chain, will decrease the amount of animals below it i.e. rabbits, squirrels, ect. and/or it will be over populating the animal above it on the food chain therefore making the food chain and way of life not balanced.

When the chain length of carbon increase the flammability decrease.
The energy flux of a food chain goes from producer to decomposer. The energy flux along the food chain is always unilateral.
Boiling points of hydrocarbons generally increase with an increase in the number of carbon atoms. This is because larger hydrocarbons have stronger London dispersion forces due to increased surface area, which requires more energy to overcome during boiling.
Decrease in higher levels.
