Understanding Carbon and Nitrogen Cycles

These flashcards cover key vocabulary related to carbon and nitrogen cycles, as discussed in the lecture on ecosystems and nutrient cycling.

Carbon

An element that is a fundamental component of all living organisms and is processed in various forms throughout the Earth's systems.

Nitrogen

An essential element for all living organisms, particularly vital for the formation of proteins and enzymes.

Chlorophyll

The green pigment found in plants that plays a crucial role in photosynthesis by capturing light energy.

Nitrogen Fixation

The process of converting nitrogen gas (N2) from the atmosphere into a usable form, such as ammonium, for plants.

Nitrification

The conversion of ammonium into nitrates and nitrites in the soil, which plants can then absorb.

Denitrification

The process by which microorganisms convert nitrates and nitrites back to nitrogen gas (N2), releasing it into the atmosphere.

Ecosystem Function

The role an ecosystem plays in moving and cycling nutrients through various living and non-living components.

Vegetative Cover

The layer of plant material covering the soil, essential for preventing soil erosion and maintaining nutrient cycling.
