The answer: the carbon cycle and nitrogen cycle
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.
It is necessary for water, carbon, nitrogen, and oxygen to be recycled through Earth's ecosystems to maintain the balance of these essential elements for life. This cycling ensures that nutrients are continuously available for organisms to grow, reproduce, and maintain their life functions. Any disruption to this cycle can have detrimental effects on the environment and biodiversity.
because we have only a limited amount of matter on earth
Energy flow through an ecosystem because it is continuously converted from one form to another as organisms consume and release energy through metabolic processes. Unlike matter, which can be recycled within an ecosystem through nutrient cycles, energy must constantly enter the system from the sun and is eventually lost as heat.
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
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.

Yes, iridium can be recycled and must be recycled because is very rare and expensive.

Matter such as water, carbon, oxygen, and nitrogen must be recycled in the environment because they are essential for sustaining life. These elements are continuously used by living organisms in various processes such as respiration, photosynthesis, and nutrient cycling. Recycling ensures that these elements are continually available for different organisms to utilize, promoting ecosystem balance and health.
Matter must be recycled on Earth to maintain a balance in nature and ensure sustainable use of resources. Recycling helps reduce energy consumption, minimize waste, and protect the environment by reducing the need to extract raw materials. It also conserves natural resources and reduces greenhouse gas emissions associated with extracting and processing new materials.
Matter and energy must be cycled on Earth to sustain life and maintain balance in ecosystems. The cycling of these resources allows for the continuous flow of nutrients and energy through different organisms and helps to regulate Earth's systems, such as the carbon and water cycles. Additionally, cycling matter and energy helps to minimize waste and maximize efficiency in natural processes.
Mercury (as metal) can and must be recycled.
Carbon dioxide is the one component in photosynthesis that is not recycled and must be constantly available in order for the process to continue.
Yes, mineral salts can be recycled through processes like desalination, where they are extracted from seawater or brackish water. These salts can also be recovered through precipitation or crystallization techniques from industrial waste streams, creating a closed-loop system for their reuse. Recycling mineral salts helps conserve resources and reduce the environmental impact of their extraction.
