Carbon
Nitrogen cycle
There are 14 essential plant nutrients. Carbon and oxygen are obtained from the atmosphere, and the other nutrients are absorbed from the soil.
Nitrogen is obtained by the plants in the mineral form.
Nitrogen is the most abundant element in the Earth's atmosphere. Bacteria in the soil 'fix' the nitrogen gas into compounds which can be taken in by plants; the plants get eaten by animals & they use the nitrogen to make proteins.
Fossil fuel is obtained from plants by the process of photosynthesis.

Yes
Nitrogen is not very reactive

Uranium can be detected in the atmosphere near uranium plants and mines. Working with care the concentration is extremely low and without significance.But if the sample is sufficiently great any element can be detected in any atmosphere.

The plants take in carbon dioxide given off by the fish during the day
NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.
Rhizobia are known as nitrogen fixation bacteria. Nitrogen is an essential element for plants and it is plentiful in the atmosphere but in a form that is inaccessible to plants. Rhizobia can convert atmospheric nitrogen into a form that plants can uptake through their roots.
