Which terrestrial and aquatic ecosystems have the highest NPP Why do you think this is?
AP Chapter 54 – Ecosystem Ecology (detailed)
|Which terrestrial ecosystem has the highest average net primary productivity?||tropical rain forests.,|
|Which freshwater ecosystem has the highest average net primary productivity?||swamps and marshes,|
Which kinds of ecosystems have the highest NPP Why?
- Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. …
- In rain forests, plants have constant high levels of water and light (at canopy level) and the nutrient supply is as high as possible, due to rapid decomposition.
Which 3 ecosystems have the highest productivity quizlet?
What types of ecosystems have the highest productivity per unit area? Estuaries, swamps and marshes, tropical rain forests, and temperate rain forests.
What biomes have high NPP low NPP Why?
Biomes with more vegetation have higher NPP levels (tropical rainforest has the most). Important because it can be an indicator for studying health of diff plants.
Why do swamps have high NPP?
Net primary production (NPP) is highest in wetlands receiving nutrient enrichment or with high nutrient turnover. The degree, duration, and periodicity of flooding affect wetland productivity more than rainfall or temperature. Drainage can promote enhanced productivity by increasing nutrient mineralization.
Which season has the highest NPP?
In mid-latitudes, productivity is obviously tied to seasonal change, with productivity peaking in each hemisphere’s summer. The boreal forests of Canada and Russia experience high productivity in June and July and then a slow decline through fall and winter.
What 3 ecosystems have the lowest NPP?
The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.
What are the two most productive aquatic ecosystems?
List two of the most productive ecosystems or aquatic life zones and two of the least productive. The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.
Which ecosystem would have the highest net primary production quizlet?
<Cold and dry> biomes have the highest net primary production. Water moves towards areas of <lower> salinity. Ecologists tend to divide the photic zone of lakes and ponds based on distance from the <bottom>.
What is high net primary productivity?
A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. … The presence of some forms of secondary energy can also help to increase the primary productivity rate.
