Ecosystems

Geographers classify ecosystems based on various factors, including climate, vegetation types, and geographical location. These classifications often include terrestrial ecosystems like forests, grasslands, and deserts, as well as aquatic ecosystems such as freshwater and marine environments. Additionally, they consider biotic and abiotic components, as well as how human activities impact these systems. This classification helps in understanding biodiversity and managing natural resources effectively.

Matter cycles through the biosphere primarily through biogeochemical cycles, such as the carbon, nitrogen, and water cycles, where elements are reused and transformed by biological, geological, and chemical processes. Energy flows through ecosystems in a linear pathway, starting from the sun, which is captured by primary producers through photosynthesis and then transferred to consumers and decomposers in food webs. This energy flow diminishes at each trophic level due to metabolic processes, with energy lost as heat. Ultimately, while matter is recycled, energy is constantly inputted from external sources and dissipated.

The cyclic flow of nutrients between biotic (living) and abiotic (non-living) components is called a nutrient cycle. This process involves the transfer of essential nutrients, such as carbon, nitrogen, and phosphorus, through various ecosystems, where they are utilized by organisms and returned to the environment. These cycles are crucial for maintaining ecosystem health and supporting life. Examples include the carbon cycle, nitrogen cycle, and phosphorus cycle.

The opposite of abiotic is "biotic," which refers to all living components in an environment. Biotic factors include plants, animals, fungi, and microorganisms that interact with each other and their surroundings. Together, abiotic and biotic factors shape ecosystems and influence the survival of organisms.

Additionally, temperature affects oxygen levels in the water, impacting the survival of different species. Overall, the temperature dynamics help shape the ecological interactions and productivity within the Mono Lake environment.

Athlete's foot is a biotic condition caused by a fungal infection, specifically by fungi from the genus Trichophyton. It is characterized by symptoms such as itching, redness, and peeling skin, typically affecting the feet. Since it involves living organisms (the fungi), it falls under the category of biotic factors.

Swamps differ from marshes primarily in their vegetation; swamps are characterized by the presence of woody plants and trees, whereas marshes are dominated by herbaceous plants like grasses and reeds. Additionally, swamps typically have a higher water table and can support a wider variety of wildlife. Both ecosystems are wetlands, but their distinct plant communities and hydrology set them apart.

In secondary succession, trees grow in areas where a disturbance has cleared existing vegetation but left the soil intact, such as after a forest fire or logging. Initially, pioneer species like grasses and shrubs colonize the area, improving soil quality and creating conditions suitable for tree growth. As these early plants establish themselves, they facilitate the gradual arrival of larger tree species through seed dispersal and natural regeneration. Over time, mature trees dominate the landscape, leading to a more complex and diverse forest ecosystem.

Human development has significantly impacted the Everglades ecosystem through urbanization, agriculture, and water management practices. The construction of roads, levees, and canals has altered natural water flow, leading to habitat fragmentation and degradation.
