2. INTRODUCTION
Cycles in nature are fundamental processes that occur cyclically,
playing a critical role in maintaining equilibrium in ecosystems and
supporting life on Earth. This presentation will focus on key natural
cycles, particularly the water cycle, and examine how these cycles
influence our daily lives and the planet's health.
3. THE WATER CYCLE
(HYDROLOGICAL CYCLE)
One of the most
crucial natural cycles is
the water cycle, which
involves a series of
interconnected
stages—evaporation,
condensation,
precipitation, and
runoff or infiltration.
The water cycle
regulates freshwater
levels, provides
drinking water, and
influences global
temperature through
evaporation and latent
4. IMPORTANCE OF CYCLES IN
ECOSYSTEM EQUILIBRIUM
Natural cycles are vital for ecosystem balance. They regulate
resources such as water, nutrients, and atmospheric gases. Cycles,
such as carbon and nitrogen cycles, are essential for plant growth
and the food chain. Without these cycles, ecosystems could collapse,
leading to species extinction.
