A farmer implements intercropping with legumes and cereals. The combined yield is significantly higher than the expected sum of individual yields. This increased productivity can be primarily attributed to:

In plant succession, when climax is reached, the net productivity

The rate of biomass production per unit area over a time period by plants during photosynthesis is called

The primary factor limiting productivity in aquatic ecosystems is often:

Which of the following is expected to have the highest value (gm/m2/yr) in a grassland ecosystem?

…A… is required for higher primary productivity. …B… have the lowest primary productivity as the soil is deficient in moisture.

Choose the correct option for A and B

Primary productivity depends upon

Net primary productivity is utilised by

The rate of formation of new organic matter by goat in a forest ecosystem is called

Rate of conversion of light energy into chemical energy of organic molecules in an ecosystem is

In a grassland ecosystem, the gross primary productivity is 2000 g/m²/year, and the respiration loss by producers is 800 g/m²/year. What is the net primary productivity of this ecosystem?
