What is Biodiversity?

Biodiversity refers to the variety of life on Earth at all levels - from genes within species to entire ecosystems. Plant biodiversity is the foundation of most terrestrial ecosystems and supports all life on Earth.

Key Concepts

Biodiversity exists at three main levels: genetic, species, and ecosystem

Plants form the foundation of most terrestrial food webs

Higher biodiversity usually means more stable ecosystems

Every species plays a unique role in its ecosystem

Biodiversity provides ecosystem services essential for human survival

The Three Levels of Plant Biodiversity

Genetic Diversity

Variation within species

Example: Different varieties of tomatoes (cherry, beefsteak, heirloom) all belong to Solanum lycopersicum

Species Diversity

Number of different species

Example: A forest might contain oak, maple, pine, fern, and moss species

Ecosystem Diversity

Variety of habitats and communities

Example: Tropical rainforests, temperate grasslands, alpine meadows, wetlands
