20 What Keeps Nature's Living and Non-Living Components in Balance?

In every habitat on Earth, living beings rely directly on physical conditions and neighboring organisms to survive. When a single component is damaged or removed, the entire biological network experiences widespread effects.

At the core of ecology is the ecosystem, which unites living organisms with their non-living physical environment. Producers create their own food, consumers depend on plants or animals, and decomposers recycle dead organic material. Together, these living groups connect with sunlight, temperature, soil, and water through structured energy flows and nutrient cycles.

• Natural ecosystems encompass terrestrial environments like grasslands and deserts as well as aquatic environments like freshwater and brackish mangroves.
• Man-made ecosystems include agricultural crop fields of wheat or rice, gardens, dams, and reservoirs.
• Heavy rainfall in tropical evergreen rainforests acts as a limiting factor by leaching essential soil nutrients required for seeds.
• Light provides vital benefits such as vitamin D synthesis for humans, though ultraviolet rays represent a harmful spectrum.
• Cold-climate species like snow leopards adapt to mountain conditions, but overall species diversity decreases at higher altitudes.

Brackish water aquatic ecosystems specifically include coastal environments such as wetlands, mangroves, and estuaries.
