Where GPP is gross primary productivity and R producer is photosynthate ( Carbon ) lost via cellular respiration.
22.
Low levels of nitrogen and phosphorus have also been found to limit plant growth and net primary productivity.
23.
The enrichment is not only in primary productivity but also secondary productivity in the form of abundance in fish populations.
24.
Grazing food webs are more important in grasslands, where over half of net primary productivity may be consumed by herbivores.
25.
A study from 2008 claims that CO 2 could increase primary productivity, particularly in eel grasses in coastal and estuarine habitats.
26.
Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains.
27.
Canopy trees are able to photosynthesize relatively rapidly due to abundant light, so it supports the majority of primary productivity in forests.
28.
Scientific studies indicate that the reservoir is productive as regards fisheries, with the reservoir water indicating a moderate-to-high rate of primary productivity.
29.
Dogger Bank has been identified as an oceanic environment that exhibits high primary productivity throughout the year in the form of phytoplankton.
30.
Detritus food webs are more important in forests, where less than 5 % of net primary productivity may be consumed by herbivores.
