Is it difficult for organisms in the dessert to access nitrogen ,phosphorus, carbon , and water

Took me a while but here it is

Carbon exists in the air, water, and living organisms already.

During Cellular respiration, some of the carbon is released back into the atmosphere as carbon dioxide.

Producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis. Then consumers obtain carbon from the carbohydrates in the producers they eat.

Some carbon is stored in limestone forming one of the largest "carbon sinks" on Earth.

Carbon is stored in the bodies of organisms as fat, oils, or other molecules, they may be released into the soil or air after an organism dies. These molecules may form deposits of coal, oil, or natural gas, which are known as fossil fuels. Fossil fuels store carbon left over from bodies of organism that died millions of years ago. Some carbon enters a long-term cycle as well. Carbon can be converted into carbonates, which make up the hard parts of bones and shells.

Humans affect the carbon cycle as well. humans burn fossil fuels, releasing carbon into the atmosphere. The carbon returns to the atmosphere as carbon dioxide.

The Nitrogen cycle is the process in which nitrogen circulates among the are, soil, water, plants, and animals in and ecosystem. All organisms need nitrogen to build proteins which are used to build new cells. nitrogen makes up 78 percent of the gases in the atmosphere.

Nitrogen must be altered or fixed before organisms can use it. Only a few species of bacteria can fix atmospheric nitrogen into chemical compounds that can be used by other organisms.These bacteria re known as "nitrogen-fixing" bacteria. these bacteria live within the roots of plants called legumes, which include beans, peas, and clover. The bacteria use sugar provided by the legumes to produce nitrogen containing compounds such as nitrates. Excess nitrogen fixed but the bacteria is released into the soil. Lighting converts some atmospheric nitrogen into nitrates that organisms use.

Nitrogen stored within the bodies of living things is returned to the nitrogen cycle once those organisms die. Decomposers break down urine, dung, leaves, as well as plant and animal wastes. After decomposers return nitrogen to the soil, bacteria transforms as small amount of the nitrogen into nitrogen gas, which then returns to the atmosphere to complete the nitrogen cycle.

Phosphorus is an element that is part of many molecules that make up the cells of living organisms. Plants get the phosphorus they need form soil and water, while animals get their phosphorus by eating plants or other animals that have eaten plants. The phosphorus cycle is the cyclic movement of phosphorus in different chemical forms from the environment to organisms and the back to the environment.

Phosphorus may enter soil and water when rocks erode.Small amounts of phosphorus dissolved as phosphate, which moves into the soil. Plants absorb phosphates in the soil through their roots. Some phosphorus washes off the land and ends up in the ocean. Because many phosphate salts are not soluble in water, they sink to the bottom and accumulate as sediment.

Fertilizers, which people us to stimulate and maximize plant growth, contain both nitrogen and phosphorus. Excessive amounts of fertilizer can enter terrestrial and aquatic ecosystems through runoff. Excess nitrogen and phosphorous can cause rapid growth of algae. Excess algae can deplete an aquatic ecosystem of important nutrients such as oxygen, on which fish and other aquatic organisms depend.
