Which one of the following atoms most often limits the primary productivity of an ecosystem?

Solution: Carbon is the element which limits the productivity of ecosystem.

Which atom limits the primary productivity of an ecosystem?

It mainly utilizes carbon dioxide, water, and sunlight. Thus the carbon acts as a limiting atom in the primary productivity.

What are three factors that may affect the primary productivity of 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.

Which of the following ecosystem has very little primary productivity?

So, the correct answer is “rivers”.

IMPORTANT:  Your question: What elements are recycled in an ecosystem?

Which one of the following ecosystems is more productive in terms of carbon dioxide fixation?

mature forest and are more productive in terms at productivity.

Which productivity of primary producers can be used by other trophic levels?

So, the correct answer is ‘Net Primary Productivity’. Note: From one trophic level to the next trophic level only 10% of energy will be transferred and 90% of the energy gets lost.

What is the annual net primary productivity of whole biosphere?

The annual net primary productivity of the whole biosphere is approximately 170 billion tons dry weight of organic matter.

What limits the primary productivity of the ocean?

In the vast unproductive low- and mid-latitude ocean, warm and sunlit surface water is separated from cold, nutrient-rich interior water by a strong density difference that restricts mixing of water and thereby reduces nutrient supply, which becomes the limiting factor for productivity.

What limits the net primary production in aquatic ecosystems?

What limits the net primary production in aquatic ecosystems such as lakes and streams? The amount of light energy converted to chemical energy by an ecosystem’s autotrophs in a given time period is an ecosystem’s primary production, limits the net primary production in aquatic ecosystems such as lakes and streams.

What factors limit the amount of primary production?

Lack of water is the main limit on primary production on the Earth’s surface. It has been found that in any area where there is an adequate water supply there will be a large amount of primary production. Water is primarily supplied through rain and the Earth’s weather system.

Which of the following is responsible for low productivity of aquatic?

It is because in oceans, productivity is limited by light which decreases with increasing water depth.

Which of the following is responsible for low productivity of aquatic habitat?

In ocean, there is insufficient radiation as sunlight decreases with the increasing depth which decreases the rate of photosynthesis. Decrease in rate of photosynthesis decreases the growth of aquatic plants and animals. Minerals and nutrients can also be a retarding factor based on location of the oceans.

Which of the following is aquatic ecosystem?

Aquatic ecosystems include oceans, lakes, rivers, streams, estuaries, and wetlands. Within these aquatic ecosystems are living things that depend on the water for survival, such as fish, plants, and microorganisms.

Which aquatic ecosystem has the highest net 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.

Which biome has the highest net primary productivity?

Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

What is primary productivity in environmental science?

primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers (photoautotrophs), which obtain energy and nutrients by harnessing sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation.
