238U and 14C are radioactive isotopes of natural chemical elements.
Yes, steel rusts and over time it will decay.

Some quantities decrease by a fixed proportion (not fixed amount) in each time period. Typical examples used in school mathematics are depreciation or radioactive decay. The value of an asset (often a car) is assumed to lose x% of its value every year. That is, at the end of each year, its value is (1-x/100) times what it was a year earlier. Similarly, radioactive substances lose y% of their mass through nuclear decay in each time period. The factor (1-x/100) is known as the decay factor.
Lack of improvements caused factories to decay.
Respiration, photosynthesis, and decay are all integral components of the carbon cycle. This cycle describes the continuous movement of carbon among the atmosphere, oceans, soil, and living organisms. Photosynthesis captures carbon dioxide from the atmosphere, while respiration releases it back, and decay returns carbon to the soil, completing the cycle. Together, these processes help maintain the balance of carbon in the ecosystem.
The decay of biomass means that biomass which is wood or litter is slowly decaying meaning that it is falling to pieces and slowly rotting away.
Carbon is not 'moved' from the atmosphere. It can be absorbed and stored by things like plants and animals, but when they die and decay the carbon will go back into the carbon cycle again. Try googling 'carbon cycle'
The process of deforestation, where trees are cut down and burned or left to decay, releases carbon dioxide into the atmosphere. This is because trees store carbon in their biomass, and when they are removed, this carbon is released back into the air through decay or burning.
Carbon is the element at the base of all known life in the universe. The carbon cycle begins with carbon received on Earth from meteorites and continues with the normal death and decay of organic life.
The decay process needs oxygen for it to happen. The surface of the compost heap will decay faster than the material 'buried' deeper in the pile. Regular mixing of the compost ensures air gets right into the heap - speeding up the decay process.

The decay bacteria fit in with the carbon dioxide oxygen cycle by releasing CO2 into the water. Aquatic plants then take this CO2 and use it to produce energy while releasing O2 back into the water.
Decay is a crucial process in the carbon cycle as it breaks down dead organic matter, releasing carbon back into the atmosphere and soil. This decomposition enriches the soil with nutrients, promoting plant growth and facilitating the uptake of carbon dioxide through photosynthesis. Additionally, decay helps maintain ecological balance by recycling nutrients and supporting various organisms in the ecosystem. Without decay, carbon would accumulate in dead matter, disrupting the flow and availability of essential nutrients.
In the short-term cycle, plants convert carbon dioxide into carbohydrates. Organisms eat the plants and obtain carbon, and then release it back into the air as carbon dioxide. Carbon is also released through wastes and decay of their remains.
One term for the process is the carbon cycle, or at least the biologic part of that cycle.
