Ciclos biogeoquímicos

Biogeochemical Cycles Overview

Ciclo Hidrológico (Water Cycle)

• The water cycle refers to a series of processes that enable the circulation and transformation of water on Earth.

• Water can change its state depending on the process, transitioning from vapor to liquid and from liquid to solid.

Ciclo del Nitrógeno (Nitrogen Cycle)

• In this cycle, bacteria and plants absorb gaseous nitrogen and fix it into their bodies.

• This fixed nitrogen is then transferred to other living organisms, serving as an essential source for life in both animals and humans.

• The nitrogen cycle occurs over short periods and is primarily gaseous in nature.

Ciclo del Carbono (Carbon Cycle)

• The carbon cycle is crucial for life on Earth, as carbon is present in the atmosphere, oceans, and soils.

• All known life forms are composed of compounds derived from carbon, making its cycle fundamental for biological existence.

Ciclo del Azufre (Sulfur Cycle)

• In the sulfur biogeochemical cycle, sulfur must undergo various oxidation states after combining with oxygen.

• This process allows sulfur to be transmitted to plants, which then pass it along to primary consumers in the food chain.

Ciclo del Oxígeno (Oxygen Cycle)

• The oxygen cycle is complex; living organisms utilize oxygen through various chemical processes.

• Both animals and humans breathe in oxygen while continuously generating carbon dioxide as a byproduct.

Ciclo del Fósforo (Phosphorus Cycle)
