Why does primary productivity vary in different types of ecosystems?
State the relation between gross and net primary productivity.
Explain what does the equation given below show :

Secondary productivity is rote of formation of new organic matter by ______.
The biomes energy available for consumption by herbivores is called ______.
Which one of the following ecosystem is most productive in term of net primary production?
Which one of the following ecosystem has the highest annual net productivity?
Why is the rate of assimilation of energy at the herbivore level called secondary productivity?
Primary productivity varies from ecosystem to ecosystem. Explain?
Justify the following statement in terms of ecosystem dynamics. “Nature tends to increase the gross primary productivity, while man tends to increase the net primary productivity”.
Which of the following ecosystems will be more productive in terms of primary productivity? Justify your answer. A young forest, a natural old forest, a shallow polluted lake, alpine meadow.
The primary productivity in an ecosystem is expressed as ______.
- gm-2 yr-1
- gm-2 yr
- Kcal m-2 yr-1
- Kcal m-2
Use the information provided in the table given below to answer the following questions:
| Tropic level | Net Production(KJm-2y-1) | Respiration (KJm-2y-1) |
| Top Carnivore | 50 | 35 |
| Carnivores | 420 | 378 |
| Herbivores | 4490 | 4041 |
| Producers | 45000 | 40,367 |
- Calculate the gross primary productivity.
- Analyze the trend in the Net Production from Producers to Top Carnivore. Give a reason for your observation.
In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is 100x(kcal m−2) yr−1, what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?
