The boreal forests of Canada and Russia experience high productivity in June and July and then a slow decline through fall and winter. BioScience The rates at which the heterotrophic organisms resynthesise the energy-yielding substances are called secondary productivity. Increases in productivity depend on nutrient distribution and the presence of moisture, which … Quiz. This chapter introduces the major abiotic constraints that species face in hot deserts and discuss how organisms, primarily from the plant kingdom, have adapted to circumvent these constraints. For the VGPM, net primary production is a function of chlorophyll, available light, and the photosynthetic efficiency.
