Why Some ecosystems are more productive than others quizlet?

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.

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.

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 of the following biomes are more productive in terms of net primary productivity?

In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.

What ecosystem is considered one of the most productive ecosystems in the world?

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.

Which ecosystem is most productive Why?

Humans and Energy Consumption

Ecosystem Type Surface area (x 106 km2) NPP (Pg)
Other terrestrial (chapparral, bogs, swamps, marshes) 6 10.7
Subtotal terrestrial 147 132.1
Lakes and streams 2 0.8
Marine 361 91.6

What are the most productive and least productive ecosystems?

Globally, patterns of primary productivity vary both spatially and temporally. The least productive ecosystems are those limited by heat energy and water like the deserts and the polar tundra. The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen.

What factors determine the 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.

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 difference between ecosystem resistance and ecosystem resilience?

Resistance is the ability for an ecosystem to remain unchanged when being subjected to a disturbance or disturbances. … Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state.

Why are some biomes 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.

Is our biome ecosystem highly productive?

As you might expect, the terrestrial biome with the highest level of primary productivity is the tropical rainforest biome with around 2,200 grams of biomass per square meter per year. The tropical seasonal forests also fall in the range of having high primary productivity.

Why is productivity of tundra biome very low?

The tundra has some of the lowest net primary productivity of any ecosystems, due mainly to the cold and short growing season, and the infertile soils.

What ecosystems are the least productive in the world?

Deserts, tundra, and the deep ocean are the least productive ecosystems, typically having an energy fixation of less than 0.5 × 103 kilocalories per square meter per year (thousands of kcal/m2/yr; it takes one calorie to raise the temperature of one gram of water by 34°F [1°C] under standard conditions, and there are …

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 estuaries are more productive?

Estuaries are one of the most productive ecosystems on earth. They maintain water quality through natural filtration as microbes break down organic matter and sediments bind pollutants. Wetlands that fringe many estuaries also have other valuable functions.
