What contributes to high productivity in an ecosystem quizlet?

What contributes to high productivity in an ecosystem?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

What is productivity What ecosystem would have the highest productivity?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What determines the productivity of an ecosystem quizlet?

What determines the productivity of an ecosystem? Via photosynthesis, producers are able to capture solar energy. Gross primary productivity (GPP) measures this over a given amount of time. How efficiently is energy transferred between trophic levels in an ecosystem?

Which ecosystem is the most productive quizlet?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

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).

What is productivity in ecosystem Class 12?

In ecology, productivity refers to the rate of formation of biomass in the ecosystem. It can also be referred to as the energy accumulated in the plants by photosynthesis. There are two types of productivity, namely: Primary Productivity.

Which ecosystem has highest biomass productivity?

Answer: Forest ecosystem have the maximum biomass, because it includes organisms of all tropic levels as compared to pond, lake or grassland ecosystem. In forest ecosystems productivity is also high that contributes to maximum biomass.

Why do coral reefs have high productivity?

Coral reefs’ high productivity has been attributed mainly to photosymbioses between the coral animal and algae of the family Symbiodiniaceae, with recognition that the host can increase algal photosynthesis by concentrating nutrients and enhancing the efficiency of light absorption.

What are the different types of productivity in an ecosystem?

According to Odum there are three types of productivities – primary productivity, secondary productivity and community productivity.

What determines the productivity of an ecosystem apes?

What determines the productivity of an ecosystem? The amount of energy in an ecosystem, determines how much life it can support. … They are fairly low as if there is the total biomass available at a given trophic level, only about 10% is only converted to the next trophic level as energy.

What is the primary productivity of an ecosystem quizlet?

The net primary productivity of an ecosystem is 1 kg C/m2/year, and the energy needed by the producers for their own respiration is 1.5 kg C/m2/year.

What are the five categories of ecosystem services?

More About Ecosystem Services

  • Provisioning Services or the provision of food, fresh water, fuel, fiber, and other goods;
  • Regulating Services such as climate, water, and disease regulation as well as pollination;
  • Supporting Services such as soil formation and nutrient cycling; and.

What might a productive ecosystem be based on?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

What is one of the most productive ecosystems on Earth?

Estuaries are a home to many plant and animal species and are considered to be one of the most productive ecosystems on earth.

What types of ecosystems are Earth’s most productive ecosystems?

Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem.
