Section 3_ The Vital Dance_ Ecosystems Cycles

Carbon-Oxygen Cycle

A biogeochemical process where carbon and oxygen are exchanged between the atmosphere, living organisms, and the geosphere.

Photosynthesis

The process by which plants convert sunlight energy to produce food (sugars) and release oxygen (O2).

Cellular Respiration

The process in which living organisms break down food molecules to generate energy, utilizing oxygen (O2).

Nitrogen Cycle

The cycle that ensures the continuous supply of usable nitrogen for plants, supporting ecosystem balance.

Nitrogen-Fixing Bacteria

Bacteria that convert atmospheric nitrogen (N₂) into ammonia (NH₃), making it usable for plants.

Decomposers

Organisms such as fungi and bacteria that break down dead organisms and waste, recycling nutrients back into the soil.

Amino Acids

The building blocks of proteins, essential for plant growth and development.

Greenhouse Gas

A gas that traps heat in the atmosphere, such as carbon dioxide (CO2), influencing Earth's climate.

Chlorophyll

The pigment in plants that captures sunlight energy for photosynthesis.

Ecosystem Balance

The state in which the various components of an ecosystem, including species and nutrients, are maintained in harmony.
