What are ecosystem functions?
Ecosystem function is the capacity of natural processes and components to provide goods and services that satisfy human needs, either directly or indirectly (de Groot et al 2002). Ecosystem functions are conceived as a subset of ecological processes and ecosystem structures.

What is the role of primary producers in an ecosystem?
Primary producers are the foundation of an ecosystem. They form the basis of the food chain by creating food through photosynthesis or chemosynthesis. … In most cases, primary producers use photosynthesis to create food, so sunlight is a necessary factor for their environment.

Ecosystems regulate the global climate by storing greenhouse gases. For example, as trees and plants grow, they remove carbon dioxide from the atmosphere and effectively lock it away in their tissues.
What are the 4 functions of the environment?
