An open ocean has the lowest net primary production per square meter.
An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors. Along with rocks, temperature and humidity are abiotic variables. Every component of an ecosystem is directly or indirectly dependent upon every other component. An ecosystem's temperature changes frequently have an impact on the types of plants that may flourish there, for example. Animals who rely on plants for food and refuge will need to relocate to a different ecosystem to adapt to the changes.
