Why is the rate of assimilation of energy at the herbivore level called secondary productivity?
Primary productivity varies from ecosystem to ecosystem. Explain?
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?
