An ecosystem is a community in which the abiotic and biotic factors interact with each other. It is an autonomous and regulating system where the living and non-living things work together through cyclic nutrient and energy flow.

The limiting factors vary among each ecosystem, wherein in a terrestrial ecosystem, theavailability of moisture and temperature to produce heat controls the growth rate of producers.

At the same time, consider an aquatic ecosystem, where sunlight exposure and nutrient supply help maintain the production rate.

Theecologist can manipulate the nutrient supply to understand the factors that limit the growth of the primary producers. The phosphorus content in soil determines the production rate of primary producers. By increasing this nutrient, the production increases with other factors available.

Similarly, when a plant is placed in the dull light region, it affects the photosynthetic activity, thereby growth. Thus, an ecologist can understand the limiting factors that inhibit the growth of producers and how manipulating the resources increases their production rate.
