Calories in. Calories out. A calorie is just a way to measure the energy created and spent by eating. This is just a simplified answer.
Energy can be lost in a food chain by heat or waste.
energy
Heat energy
Energy is lost in a living system through processes like respiration, where a portion of the energy from food is released as heat. Energy is also lost as heat during various metabolic processes and as waste products are eliminated from the body. Additionally, energy can be lost through inefficiencies in energy transfer between trophic levels in a food chain.
Energy is lost in a food web through various mechanisms such as heat loss, incomplete digestion, and metabolic processes. When organisms consume food, only a portion of the energy is transferred to the next trophic level, with the rest being lost as heat during metabolic processes. Additionally, energy is lost through waste production and respiration, further reducing the overall energy available in the food web.
Once energy is lost in a food chain, it cannot be recovered. Energy is continually lost as heat through metabolic processes and other activities, leading to a decrease in available energy as it moves through trophic levels in a food chain. This is known as the second law of thermodynamics.
Heat and excretement and tuna!
Because it is lost at the end .
Energy lost in a food chain is converted into heat and cannot be reused by organisms. This is known as the second law of thermodynamics, which states that energy is not created or destroyed, only transferred and transformed.
To live things use energy. They have to eat other tings for food unless they are plants, which can make their on food by trapping Sunlight energy.
The energy not used for life processes is lost as heat. This excess energy is released as heat when organisms metabolize food for energy. This heat is then dissipated into the environment.
I dont know thats why i asked!
