Is an example of an ecosystem with high primary productivity while A?

What is an example of an ecosystem with high primary productivity?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

What is an example of an ecosystem with low primary productivity?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome. These biomes include habitats that have extreme temperatures and very limited precipitation, which results in very low production of new biomass.

Which 3 ecosystems have the highest productivity?

The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).

Is an example of a resource provided by our ecosystems while is an example of a service provided by our ecosystems?

ecotone (Ecotones occur where ecosystems meet and form a transitional zone, where elements of each ecosystem mix.) … water, water cycling (Water is a resource, and the ability of an ecosystem to purify water and return it to Earth in the water cycle is a service that the ecosystem provides for us, free of charge.)

What is high primary productivity?

The primary productivity of an ecosystem is defined as the speed at which the solar energy is turned into an organic substance by chlorophyll in the photosynthesis. … A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable.

Which of the following ecosystem has the highest gross primary productivity?

In the aquatic ecosystem, coral reefs show the highest gross primary productivity. Large numbers of aquatic phototrophs and phytoplankton contribute to the productivity of the ecosystem.

What three ecosystems have the lowest productivity?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.

What is the gross primary productivity of an ecosystem?

Gross primary productivity is the amount of carbon fixed during photosynthesis by all producers in the ecosystem. However, a large part of the harnessed energy is used up by the metabolic processes of the producers (respiration).

What is primary production and examples?

The primary production stage of the supply chain encompasses agricultural activities, aquaculture, fisheries and similar processes resulting in raw food materials. … Examples of primary production activities are: farming, fishing, livestock rearing and other production methods.

Which ecosystem is highly productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Where is the GPP the highest?

The highest GPP values are in tropical regions (e.g. Amazonia, Central Africa and Southeast Asia) because of the wet and humid climate; and, the lowest GPP values are mainly in the arid regions of North Africa, West Asia and South America, as well as the cold and snow-covered regions (e.g. Greenland), due to the …

What is net primary productivity?

Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

What are examples of ecosystem services?

Examples of ecosystem services include products such as food and water, regulation of floods, soil erosion and disease outbreaks, and non-material benefits such as recreational and spiritual benefits in natural areas.

Which example is not an ecosystem service?

Conditions or processes of ecosystems that cannot be linked to the welfare of identifiable beneficiary groups are not ecosystem services. For example, changes in fish abundance in areas not used by humans and that have no direct or indirect effect on human benefits are not ecosystem services.

Which of the following represents an example of a regulating ecosystem service?

Regulating services include pollination, decomposition, water purification, erosion and flood control, and carbon storage and climate regulation.
