Why is our ecosystem highly productive?

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 makes an ecosystem highly productive?

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.

Which ecosystems are most productive and why?

What are the two most productive land ecosystems? The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

Why Some ecosystems are more productive than others?

Why are some ecosystems or biomes more productive than others? Tropical rainforest: High productive rate because warm temp is ideal for photosynthesis, and high global productivity. Open oceans: Low rates of production, but ALOT of global productivity. … We depend on ecosystems for goods and services.

IT\'S FUNNING:  What is not an indicator of global environmental stress?

Which ecosystem is more productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Why is primary productivity important?

Primary productivity is the conversion of the sun’s energy into organic material through photosynthesis. … Primary productivity is important because it is the process that forms the foundation of food webs in most ecosystems.

Why are coral reefs the most productive ecosystems?

The coral reefs are known to possess the most productive ecosystem on the earth. … The animals living under the coral reefs swiftly filter the water and allow planktonic organisms to grow, and these plankton get enough sunlight to grow.

Why are wetlands the most productive ecosystems?

Wetlands are highly productive and biologically diverse systems that enhance water quality, control erosion, maintain stream flows, sequester carbon, and provide a home to at least one third of all threatened and endangered species. Wetlands are important because they: improve water quality. provide wildlife habitat.

What factors do you think contribute to such high productivity?

9. What factors do you think contribute to such high productivity? – They have the most amount of primary producers available and the least amount of consumers.

Why do wetlands have high productivity?

Low or intertidal marshes are more productive than high marshes because of the increased exposure to tidal flow. Belowground production is high. Under unfavorable soil conditions, plants seem to put more energy into root production. … Generally, plant production depends on light, water, nutrients, and toxins.

Why does primary productivity vary from ecosystem to ecosystem?

The primary productivity varies from ecosystem to ecosystem as it depends on the plant species and the environmental surrounding and its ability to carry out photosynthesis. … It also depends upon other factors like soil conditions, moisture, temperature, etc.

IT\'S FUNNING:  You asked: Are any milk cartons recyclable?

Why does high biodiversity result in higher productivity?

Why does high biodiversity result in higher productivity? A variety of plants can exploit every niche and possibly help others get started. … More varied habitats means more different species are adapted to them and live in them, leading to high species richness and high biodiversity.

What world ecosystem have high and low net productivity Why?

About 40 to 85 percent of gross primary productivity is not used during respiration and becomes net primary productivity. The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
