The correct increasing order for the daily net primary productivity (NPP) per unit leaf area in different ecosystems is:

Temperate forests < Tropical forests < Deserts

This order indicates that deserts have the lowest NPP per unit leaf area, followed by tropical forests, and then temperate forests.

Deserts typically have low NPP due to factors such as limited water availability and extreme environmental conditions. The harsh conditions in deserts restrict plant growth and productivity.

Tropical forests, on the other hand, have higher NPP compared to deserts due to abundant rainfall, high temperatures, and a diverse range of plant species. These favorable conditions support rapid growth and high productivity in tropical forests.

Temperate forests fall between deserts and tropical forests in terms of NPP per unit leaf area. They receive moderate rainfall and experience seasonal variations in temperature, which influences their productivity. Hence, the correct option is 3.
