Energy flowing through a system has to come from somewhere and has to go somewhere because there are two laws of Physics that apply.
In the Biosphere the source of energy is the Sun, sunlight. This is trapped and stored by plants (producers). As plants use this energy to live and grow, they give of heat (as per law 2) so the Sun's energy is transformed.
Then along come animals that eat plants and steal the plant's food stores, these animals have to be more active than plants so, as they live and move, these too give of heat. More of the Sun's original energy is lost (as per law 2).
The plant eaters are then predated by carnivores, the carnivores steal the herbivore's food stores and use it to live and move and these too give off heat. More of the Sun's original energy is lost (as per law 2).
Thus you can see that the process of life can be looked at as a flow of energy from organism to organism with this energy gradually being lost (into space) as heat. High quality energy (visible light) straight from the Sun is transformed into low quality energy (heat) by living things.
The second law means that you can not turn low quality energy into high quality energy and this make the path of energy transformation uni-directional.
Energy enters the biosphere primarily through sunlight, which is captured by plants during photosynthesis. This energy is then transferred through the food chain as organisms consume each other. Additionally, some energy enters the biosphere through geothermal sources.
Energy in the biosphere flows through a one-way system, entering as sunlight and being converted into chemical energy through photosynthesis. This energy is then transferred through the food chain as organisms consume each other. In contrast, matter in the biosphere cycles through biogeochemical processes, such as the carbon and nitrogen cycles, where elements are taken up by organisms, recycled, and reused in the ecosystem.
Ecological
Matter cycles through the biosphere primarily through biogeochemical cycles, such as the carbon, nitrogen, and water cycles, where elements are reused and transformed by biological, geological, and chemical processes. Energy flows through ecosystems in a linear pathway, starting from the sun, which is captured by primary producers through photosynthesis and then transferred to consumers and decomposers in food webs. This energy flow diminishes at each trophic level due to metabolic processes, with energy lost as heat. Ultimately, while matter is recycled, energy is constantly inputted from external sources and dissipated.
False. In the biosphere, there is a continuous cycle of energy flow. Energy from the sun is captured by plants through photosynthesis, then transferred to herbivores, carnivores, and decomposers in a complex web of energy exchanges. This flow of energy is not one-way, but rather a continuous loop within ecosystems.

In what form does energy leave the biosphere?
Energy enters the biosphere primarily through sunlight, which is captured by plants during photosynthesis. This energy is then transferred through the food chain as organisms consume each other. Additionally, some energy enters the biosphere through geothermal sources.
Aerobic Energy Pathway
Efficiency of a respiration pathway refers to the amount of energy produced by the pathway relative to the amount of energy input. A highly efficient pathway will produce more ATP (energy) per unit of substrate consumed, resulting in greater energy yield for the organism.
Biosphere
The sun.
False. The flow of energy in the biosphere is constant and not continually decreasing. Energy enters the biosphere in the form of sunlight and is continuously cycled through ecosystems via processes like photosynthesis and respiration.
Respiration supplies energy for organisms on Earth. Respiration can either be photosynthesis in plants and fungi or cellular respiration in animals.
The primary source of energy for the biosphere is the sun. Solar energy is captured by plants through photosynthesis, which is then passed on through the food chain to other living organisms. This process fuels life on Earth and drives the biological processes within the biosphere.
Energy in the biosphere is transferred through food chains and food webs. Producers, such as plants, capture energy from the sun through photosynthesis. This energy is then passed on to consumers as they eat other organisms.

This energy is then transferred through the food chain as organisms consume each other.
