Figure 2: Ecological Productivity Explained through Food Chain

Here, gross primary productivity is the term that refers to the trapping of solar energy by the process of photosynthetic organism. All types of matters that are organic fall under the category of gross primary productivity. On the other hand, net primary productivity is described as the gross productivity minus energy lost in respiration.

It is described as the remaining part after the loss of energy. The energy is stored in plants for energy and it is used as food. The animals consume the foods and it is the amount of organic matter in a given time.

Secondary Productivity

The Secondary Productivity is mainly influenced by the heterotrophs within the ecosystem. It is nothing but the energy which is accumulated at the level of the consumer. Here, biomass generation is referred to as secondary productivity and the organic compounds helps driving this matter. The matter is also described as the biomass increase rate of the heterotrophs.

Some examples of secondary production are animals, bacteria, fungi, and other protists. The transformation of this type of productivity has happened between different trophic levels. The units of this matter are given by mass per unit volume per unit time.

Energy Movement in the Trophic Levels

It is seen that energy is the most important factor within an ecosystem and it passes from one trophic level to another. The movement happens when organic molecules present in the body of an organism are eaten by another organism. This transformation process is known as an efficient process and 10% of the energy is stored in the biomass. The process happens from the primary producers to the primary consumers.

Conclusion

The tutorial shows the importance of ecosystem as a part of productivity. Productivity mainly depends on different factors of the ecosystem and the matter including temperature, water, and land. Productivity is spanided into two main parts and they are primary and secondary productivity. The factor is also described as the increased rate of biomass as per unit area. The productivity of ecology is mainly characterised as a pyramid structure and it is depicted as food web.

FAQs

Q1. What are the features of primary productivity?

Ans. The producers mainly carry it out and it is the conversion of solar energy to chemical energy. The conversion happens through the producers of an ecosystem in a certain time period. Here, photosynthesis is an important process in the formation of biomass.

Q2. What factors are responsible for the ecosystem problem?

Ans. It is seen that the components of an ecosystem are affected by some factors. The factors include solar radiation, moisture, temperature, biotic activities, mineral nutrition, and human population. They are the main reason for the destruction of the process of ecosystem.

Q3. What are the important functions of productivity within an ecosystem?

Ans. There are four functions important in this part and the functions are productivity, energy flow, decomposition, and nutrient cycpng. The factors are responsible for bringing energy to the other pving organisms such as the decomposer and consumers.

Q4. What factors are affecting the productivity of an ecosystem?

Ans. The factors affecting productivity include nutrients, water, carbon dioxide, and sunpght. These major factors affect the system of productivity.
