Study Notes

Environment

The environment encompasses all elements surrounding a living organism, including physical factors like air, water, and soil, and biological factors like living organisms - flora and fauna.

Environmental Services

These services represent the direct and indirect benefits that ecosystems provide to human survival and quality of life.

Support Services

Support services include the cycling of vital nutrients, such as nitrogen and phosphorus, which are crucial for survival and can only be obtained in their usable forms through these cycles.
