Question

Primary productivity varies from ecosystem to ecosystem. Explain?

Answer 1

Primary productivity:

Primary productivity is the rate of organic matter that is produced per unit area over a period of time by producers in an ecosystem.

Factors affecting primary productivity:

Factors affecting primary productivity are:

• Solar radiations
• Temperature
• Moisture
• Nutrients
• Photosynthetic activity

Variation in productivity:

• Different ecosystems have different climatic conditions and species diversity.
• Species of plants inhabiting different geographical areas possess different photosynthetic activity.
• The solar radiation and nutrient availability are also different in various ecosystems.

As a result, productivity is different in various ecosystems.
