Which type of ecosystem is biologically the least productive?
The most productive ecosystems are temperate and tropical forests, and the least productive are deserts and tundras..
Which consumer gets the most energy?
Producers: Also known as autotrophs, these organisms make their own food through the process of photosynthesis. Producers make up the first trophic level, thus having the greatest overall biomass.
Which is the most productive ecosystem?
The most productive ecosystems include:Estuaries.Swamps.Marshes.Tropical rainforests.Temperate rainforests.
What organisms get the least amount of energy?
It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.
Why are oceans least productive?
(i) There is insufficient radiation as sunlight decreases with the increasing depth of the ocean. (ii) Oceans are nitrogen deficient which is an important nutrient for plants.
How do we calculate efficiency?
The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency.
Why does the 10% rule exist?
Explanation: When energy moves between trophic levels , 10% of the energy is made available for the next level. … Roughly ten percent of the previous trophic level’s energy is available to the level immediately higher up. This is called the 10% Rule.
Why is only 10 percent of energy passed on?
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
What increases net primary productivity?
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 organisms have the most energy?
Therefore, plants or producers are the organisms that have the most energy available in the food chain energy pyramid as the energy decreases from the lower to subsequent higher trophic levels.
What happens to the other 90% in the 10% rule?
Ten Percent Rule: What happens to the other 90% of energy not stored in the consumer’s body? Most of the energy that isn’t stored is lost as heat or is used up by the body as it processes the organism that was eaten.
Which 3 ecosystems have the highest productivity?
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).
Why are estuaries very productive ecosystems?
Explain why estuaries are very productive ecosystems. … Estuaries are very productive because they constantly receive nutrients from rivers and for the ocean. Estuaries are vulnerable to pollution because ocean, lake, and river pollutants enter and because dense human settlements surround most estuaries.
What is an example of allocative efficiency?
Allocative efficiency means that the particular mix of goods a society produces represents the combination that society most desires. For example, often a society with a younger population has a preference for production of education, over production of health care.
Which points are efficient?
An efficient point is one that lies on the production possibilities curve. At any such point, more of one good can be produced only by producing less of the other.
What 3 ecosystems have the lowest productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
What is production efficiency?
Production efficiency is an economic term describing a level in which an economy or entity can no longer produce additional amounts of a good without lowering the production level of another product. … Productive efficiency similarly means that an entity is operating at maximum capacity.
Which organism gets the most energy from the sun?

Where does the 90% of energy go?
Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat. The total energy passed from one level to the next is only about one-tenth of the energy received from the previous organism.
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. About what percentage of total potential net primary productivity of the entire earth and the earth’s terrestrial ecosystems are used, wasted, or destroyed by humans?
Which organism has the highest production efficiency?
PlantsPlants have the greatest net production efficiencies, which range from 30-85%. The reason that some organisms have such low net production efficiencies is that they are homeotherms, or animals that maintain a constant internal body temperature.
