energy
Nutrients are recycled in ecosystems, but not in organisms.
Energy cannot be recycled in an ecosystem. While matter like nutrients and water can be recycled within ecosystems, energy flows through the system and is eventually lost as heat.
Nutrients move through ecosystems in a cyclical manner, being recycled and reused by organisms. Energy flows through ecosystems in a one-way direction, gradually being lost as heat at each trophic level. Nutrients are often limited and must be recycled, while energy flows through and out of ecosystems.
It is recycled.
Nutrients can cycle through ecosystems because they are recycled and reused by organisms and geological processes. Energy, on the other hand, enters ecosystems in the form of sunlight and is eventually lost as heat through metabolic processes, making it a one-way flow that cannot be recycled in the same way as nutrients.

Nitrogen.
Energy is not recycled by living organisms; instead, it flows through ecosystems. Organisms obtain energy from food, which is transformed through metabolic processes to support growth, reproduction, and maintenance. While matter, such as nutrients, can be recycled within ecosystems, energy is lost as heat during these transformations, following the laws of thermodynamics. Thus, energy must be continuously supplied to living systems, primarily through sunlight in the case of photosynthetic organisms.

The amount of matter that is recycled on Earth is not easily quantifiable due to the complex and interconnected nature of Earth's ecosystems. However, it is estimated that a significant amount of matter is recycled through processes like decomposition, nutrient cycling, and waste breakdown to sustain life on the planet. Recycling of matter is essential for maintaining the balance and health of Earth's ecosystems.
The movement of energy is one-way, flowing through ecosystems from producers to consumers and decomposers. Nutrients, on the other hand, cycle through ecosystems as they are taken up by plants, consumed by animals, and then returned to the environment through decomposition. Energy is lost as heat at each trophic level, while nutrients are recycled within the ecosystem.
The movements of energy and nutrients through living systems are different because energy flows unidirectionally and cannot be recycled, while nutrients cycle within ecosystems and can be reused. Energy enters ecosystems through sunlight and is lost as heat, whereas nutrients are constantly recycled through biogeochemical processes.
