Introduction to
Biogeochemical Cycles
WhatAre Biogeochemical Cycles?
Natural pathways cycling elements through the environment and
living things.
Why They Matter
Crucial for nutrient recycling and sustaining Earth’s ecosystems.
3.
Importance of BiogeochemicalCycles in
Ecosystems
Balance & Stability
Maintain ecological balance by regulating nutrient flow.
Energy Transfer
Enable energy flow across food webs and habitats.
4.
The Water Cycle:Definition
Continuous Movement
Water cycles through atmosphere, land, and living organisms.
Processes
Includes evaporation, condensation, precipitation, and collection.

Water Cycle ProcessesExplained
Evaporation
Water turns to vapor from oceans and lakes.
Transpiration
Plants release water vapor from leaves to the air.
7.
Water Cycle: Condensation,
Precipitation& Collection
Condensation
Water vapor cools forming clouds.
Precipitation
Water falls as rain, snow, sleet, or hail.
Collection & Infiltration
Water gathers into bodies and soaks into soil.

Significance of theWater
Cycle
Supports Plant Growth
Supplies essential water to
flora.
Regulates Weather
Drives precipitation and
climate patterns.
Maintains Ecosystems
Keeps habitats healthy and balanced.
9.
The Carbon Cycle:Definition & Diagram
Carbon Cycle Defined
Movement of carbon through air, organisms, soil, and
oceans.
Key Processes
Includes photosynthesis, respiration, decomposition, and
combustion.
10.
Significance of theCarbon
Cycle
Climate Regulation
Controls atmospheric CO₂
and global temperatures.
Energy Flow
Supports food chains
through carbon transfer.
Carbon Recycling
Maintains ecosystem health by cycling organic matter.
