Robert Costanza and colleagues estimated the value of ecosystem services to be about US $33 trillion per year, nearly twice the global gross national product at that time.

Biodiversity loss adversely affects ecosystem services such as pollination, nutrient cycling, climate regulation, and water purification.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Species-Area Relationship
Ecosystem services include pollination, nutrient cycling, climate regulation, soil formation, and many other benefits essential for human well-being.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Biodiversity provides ecosystem services such as pollination, nutrient cycling, nutrient storage, climate regulation, flood control, and soil formation.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Biodiversity provides essential ecosystem services such as pollination, nutrient cycling, soil formation, climate regulation, and purification of air and water.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Ecosystem services include nutrient cycling, water purification, pollination, soil formation, and climate regulation, all of which are essential for life.

Mutualism benefits both species, such as pollinators receiving nectar while aiding plant reproduction.

Ecosystem services are most reliably sustained when multiple species make substantial contributions rather than when function is concentrated in one dominant species. Even contribution raises functional evenness: different taxa participate in production, decomposition, pollination, nutrient retention, or trophic regulation, reducing dependence on a single vulnerable contributor. It can also strengthen the “insurance effect,” because species respond differently to drought, disease, or disturbance; decline of one contributor may be offset by another. This does not mean every species performs an

Ecosystem services are benefits that functioning ecosystems supply to people, often without direct market transactions. Provisioning services include food, fibre, freshwater, and genetic resources; regulating services include pollination, climate regulation, flood moderation, and water purification. Nutrient cycling and soil formation support production, while landscapes also provide cultural and recreational value. Genetic modification and artificial intelligence are technologies, whereas industrial pollution is an ecological cost. Energy is lost as metabolic heat at every trophic transfer, w
