Energy does not move around in cycles. The reason is related to the Second Law of Thermodynamics. Here is an example: The energy from the Sun comes to Earth, where it maintains life. From Earth, the energy is radiated out into space, where it gets more and more diffuse. This energy can't be recovered again; it won't get back into the Sun - and most of it will not participate in the creation of new stars, either.
Energy is a one-way flow because it enters an ecosystem from the sun and is eventually lost as heat during various energy transformations. While nutrients can cycle within an ecosystem through processes like decomposers breaking down dead organisms, energy cannot be recycled in the same way. Once energy is used in an organism, it is not passed on in its original form.
The cycle of matter involves the recycling of elements like carbon and nitrogen through processes such as photosynthesis and decomposition. In contrast, the flow of energy involves the transfer of energy through ecosystems via sunlight and the feeding relationships between organisms. While matter is recycled, energy flows in one direction, entering ecosystems through sunlight and eventually being lost as heat.
Energy is often referred to as a flow because it moves continuously through ecosystems in one direction, from the sun to organisms and back out again. Matter, however, is recycled in a cycle because it is continuously reused and recycled within ecosystems, such as through processes like decomposition and nutrient cycling.
The sun provides energy in the water cycle.

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.

Sun is the source of energy. Energy cycle comes from it.
Cellular respiration is a cycle of matter and a flow of energy. It takes place just outside and inside the cell's mitochondria.

The energy source behind the water cycle is solar energy. It is the only energy which initiates water cycle.
Nutrients are cycled within an ecosystem, moving between living organisms and the environment, while energy flows through the ecosystem, entering as sunlight and being lost as heat during metabolic processes. Nutrients are recycled and can be reused, whereas energy is not recycled and must constantly be supplied to sustain the ecosystem.
