Earth system cycles are natural processes in which materials and energy move through the Earth's various spheres, such as the atmosphere, hydrosphere, biosphere, and geosphere. Examples include the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle. These cycles are interconnected and play a crucial role in regulating the Earth's climate and sustaining life.
The biosphere is considered an open system because it interacts with its surroundings through the exchange of energy and matter. It receives input of energy from the sun and cycles materials such as carbon, nitrogen, and water with other Earth systems.
Energy in the biosphere flows through a one-way system, entering as sunlight and being converted into chemical energy through photosynthesis. This energy is then transferred through the food chain as organisms consume each other. In contrast, matter in the biosphere cycles through biogeochemical processes, such as the carbon and nitrogen cycles, where elements are taken up by organisms, recycled, and reused in the ecosystem.
The carbon cycle is when plants convert carbon dioxide, CO2, from the atmosphere into carbohydrates, such as glucose, C6H12O6. Then, organisms eat the plants and obtain the carbon from the carbohydrates. Next, organisms' bodies break down the carbohydrates and release some of the carbon back into the air as CO2.
The respiratory system is responsible for taking in oxygen through the lungs and releasing carbon dioxide back into the environment. Oxygen is taken up by the blood in the lungs and carbon dioxide is expelled from the body through exhalation.
Carbon cycles in earth\'s system when it is excreted by animals, and then absorbed by plants.
Protists affect the Earth's heating and cooling system through processes like photosynthesis and carbon sequestration. Photosynthetic protists, like algae, help cool the Earth by absorbing carbon dioxide and releasing oxygen. Additionally, some protists play a role in regulating nutrient cycles that influence the Earth's climate.

Biogeochemical cycles are named so because they involve the cycling of elements and compounds through various components of the Earth system, including living organisms (bio-), the atmosphere, hydrosphere, and lithosphere (geo-), all interconnected in a continuous process. These cycles demonstrate how elements such as carbon, nitrogen, and phosphorus move through living organisms and their physical environment, impacting both biological and geological processes.
The energy budget is a balance because the total amount of energy entering a system is equal to the amount leaving, with no new energy being created or destroyed. The water and carbon cycles are described as circles because these elements are continuously recycled within the Earth's systems, moving through various processes and reservoirs without being lost from the system.
The biosphere is considered an open system because it interacts with its surroundings through the exchange of energy and matter. It receives input of energy from the sun and cycles materials such as carbon, nitrogen, and water with other Earth systems.
Biogeochemical cycles, such as the carbon cycle, nitrogen cycle, and water cycle, involve the movement of matter and energy between reservoirs in the Earth system. These cycles are essential for the functioning of ecosystems and sustaining life on Earth.

The respiratory system takes in oxygen through the lungs and eliminates carbon dioxide through exhalation. Oxygen is exchanged with carbon dioxide in the alveoli of the lungs during the process of respiration.
Materials are cycled through the Earth system in various ways. For example, the water cycle involves the movement of water between the atmosphere, oceans, and land. The carbon cycle involves the exchange of carbon between the atmosphere, plants, animals, soil, and oceans. These cycles are essential for maintaining balance and supporting life on Earth.
It cycles coolant through the motor's cooling system, thus regulating engine temperature.
The charging system cycles through the battery...same reason it doesn't have a kickstart.
