The nitrogen in a tropical rain forest goes through the normal nitrogen cycle steps and also gains nitrogen directly from lightning activity.
Basic Nitrogen cycle steps:
1. Nitrogen-fixation: nitrogen gas (N2) in the atmosphere is changed into ammonia (NH3) by special nitrogen-fixing bacteria in the soil.2. Nitrification: the conversion of ammonia (NH3) to nitrate (NO3-), done in two steps by bacteria. In the first step NH3 is converted to nitrite (NO2-). The second step is for NO2- to be converted into NO3-.
3. Assimilation: NH3 and NO3- compounds are taken into plants' biological tissues. Nitrogen is needed for the building of proteins and nucleic acids (DNA and RNA). Plants can use NO3- and NH3, animals obtain nitrogen by eating plants or other animals.
4. Ammonification: the conversion of organic nitrogen into ammonia (NH3); acomplished by the decomposition of organisms or waste products (urine and feces).
5. Denitrification: the process of changing NO3- to N2 gas. This is done by bacteria where there is little or no oxygen. This returns nitrogen to the atmosphere.
Role of lightning:Lightning produces NH3, NO2-, and NO3- compounds fromN2 gas in the atmosphere so nitrogen can be incorperated into the stages of the cycle without nitrogen-fixing bacteria.Lightning is an important part of the nitrogen cycle, especially in the rain forest since the soils are heavily leached. Much of the nitrogen in the soil is washed away by the rain. The lightning replenishes the soil and leaves some of nitrogen compounds in the air. Plant leaves can readily take up NO3- from the air and some plants depend on it (such as epiphytes whose roots do not reach the soil).
Estimates of how much nitrogen forests take in varies widely, but some have speculated that in a year a rainforest could take in as much as 50 pounds of nitrogen per acre.
explain how nitrogen cycles through the land and ocean ecosystems
Water, carbon, nitrogen, and phosphorus are some other substances that cycle through the environment. Water cycles through the hydrological cycle, while carbon cycles through the carbon cycle, and nitrogen and phosphorus cycle through the nitrogen and phosphorus cycles, respectively. These cycles are essential for maintaining the balance of nutrients and elements in ecosystems.
The phosphorus cycle differs from the carbon and nitrogen cycles in various ways. Phosphorus primarily cycles through the lithosphere, while carbon cycles through the atmosphere, hydrosphere, and geosphere, and nitrogen cycles through the atmosphere and biosphere. Phosphorus is often a limiting nutrient in ecosystems, while carbon and nitrogen are more abundant and play larger roles in atmospheric processes.

No, the nitrogen, carbon, and sulfur cycles are not considered part of the biogeochemical cycles in nature. These cycles involve the movement of these elements through the atmosphere, hydrosphere, lithosphere, and biosphere, but they are not exclusive to living organisms like plant and animal cycles.
The nutrient that cycles through organisms, rivers, rain, and the atmosphere is nitrogen. This nitrogen cycle involves processes such as nitrogen fixation, where atmospheric nitrogen is converted into usable forms by bacteria, and denitrification, which returns nitrogen to the atmosphere. Additionally, nitrogen is transported through water bodies and is taken up by plants and animals, highlighting its integral role in ecosystem functioning.

The three cycles that move through the ecosystem are the water cycle, carbon cycle, and nitrogen cycle. These cycles play crucial roles in maintaining the balance of nutrients and resources within the ecosystem, ensuring the survival of organisms and the functioning of ecosystems.
Phosphorus, not found in the atmosphere like carbon and nitrogen, take a longer time to move through solids. Phosphorus cycles through sedimentary rock which takes a lot longer of a process.
biogeochemical cycles, which involve the continuous movement and transformation of elements such as carbon, nitrogen, and phosphorus through living organisms and their environment. These cycles are essential for maintaining the balance of nutrients and energy within ecosystems.
"Energy flows" refers to the continuous transfer of energy through ecosystems, as it is passed from one organism to another. "Matter cycles" refers to the recycling of nutrients and elements, such as carbon, nitrogen, and phosphorus, through biogeochemical cycles like the carbon and nitrogen cycles. Together, these processes support life on Earth by allowing organisms to obtain energy and nutrients.
