Why is the rate of assimilation of energy at the herbivore level called secondary 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.
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.
