The Human Body
The major reservoirs of nitrogen include the atmosphere, which contains about 78% nitrogen gas (N2), and the soil, where nitrogen is found in various forms such as ammonium (NH4+), nitrate (NO3-), and organic matter. Additionally, nitrogen is present in aquatic systems, including oceans and freshwater bodies, where it exists in dissolved forms and organic compounds. Biological organisms, particularly in the form of amino acids and nucleic acids, also serve as significant reservoirs of nitrogen.
Reservoirs are tanks that store water during excess rainfall. later, when the dry season occurs these reservoirs (containing water) are used to fulfill the needs of people. example : for agriculture, domestic use etc. reservoirs are mostly used in countries lke india where water is needed the most.
The six major groups of pathogens are bacteria, viruses, fungi, parasites, prions, and protozoa. Each group includes various species that can cause different types of infections and diseases in humans and animals.
Bacteria and viruses that cause illness are known as pathogens.

They have established four major reservoirs.
There are four major types of human pathogens: -Bacteria -Viruses -Fungi -and Protists
The Earth's water reservoirs from largest to smallest: Ocean Polar ice and Glaciers Groundwater Freshwater Lakes Saline Lakes Soil Moisture Atmosphere Rivers
The major reservoirs of Earth's freshwater include glaciers and ice caps, groundwater, lakes, rivers, and wetlands. These sources contain the majority of the world's accessible freshwater, with groundwater being the largest reservoir.
The five major carbon reservoirs on Earth are the atmosphere, oceans, terrestrial biosphere (plants and soils), fossil fuels, and sediments (such as limestone and organic matter). These reservoirs store carbon in various forms and exchange it through processes like photosynthesis, respiration, and erosion.
The major reservoirs for water include oceans, which hold about 97% of the Earth's water; glaciers and ice caps, containing about 2%; groundwater, which accounts for approximately 1%; and surface water sources such as rivers, lakes, and wetlands. Additionally, atmospheric water vapor contributes a small but significant amount. These reservoirs play critical roles in the Earth's hydrological cycle and influence climate and ecosystems.
Human reservoirs refer to populations of humans that harbor pathogens, such as viruses or bacteria, without necessarily showing symptoms of disease. These individuals can serve as a source of infection for others, allowing diseases to spread within communities. Understanding human reservoirs is crucial for public health efforts aimed at controlling and preventing the transmission of infectious diseases. Identifying asymptomatic carriers helps in implementing effective surveillance and intervention strategies.

A major difference is that Reservoirs are man made and used for human use while other lakes are not.
