Question
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.

Solution
- Gross Primary Productivity is 45000 + 40367 = 85367 KJm-2y-1.
- Net production is gradually reducing as we move from producers to consumers due to heat loss/respiration/10% law.
