Which trophic level would contain the largest biomass?
The first trophic level has the most biomass because it has the most energy according to the 10% rule. Which level of the food pyramid has the largest biomass? The greatest biomass appears in the producer level. Every time biomass moves up the food chain some will be lost and therefor more abundant in the producers area.
What level of the food chain has the least energy?
Who gets the least energy in a food chain? Therefore, primary consumers get about 10% of the energy produced by autotrophs, while secondary consumers get 1% and tertiary consumers get 0.1%. This means the top consumer of a food chain receives the least energy, as a lot of the food chain's energy has been lost between trophic levels.
Which trophic level is most vulnerable to extinction?
Which trophic level is most vulnerable to extinction? Tertiary (third-order) consumer level. ... Why is a diagram of energy flow from trophic level to trophic level shaped like a pyramid? Most energy at each level is lost, leaving little energy for the next level.
What trophic level contains the most energy and biomass?
Trophic level 1, producers, has the lowest energy density, the energy is spread out over a vast number of individuals so has the highest biomass, whereas the level 4, apex predators, has the highest energy density and the least biomass.
Which level has the least energy in an energy pyramid?
The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.
Which trophic level has the most amount of energy?
The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller.
What trophic level has the least amount of biomass?
At the lowest trophic level, the primary producers, there is the least amount of biomass and as the trophic levels increase the biomass increases. This is known as an inverted pyramid. A pyramid such as this one occurs in aquatic ecosystems because the turnover rates of the primary producers are much higher.
Which trophic level has least organisms?
The trophic level that has the least biomass is usually the tertiary consumers. Tertiary consumers are at the top of the food web and subsequently have the least access to energy, according to the 10% rule.
Does the first trophic level have the most energy?
Explanation: Number of Organisms at the level of producers (First level) is more and hence the availability of energy also will be more at the level of producers. Amount of energy available decreases as we you move from the level of producers to the top carnivores.
At which trophic level is maximum and minimum energy available?
The maximum energy is available at T1, or the first trophic level, which is called producers. The 10% law states that only 10% of the energy present in one trophic level is transferred to the following one. On average, 10% of energy is transferred from a lower trophic level to the next higher level.
What are the 5 levels of trophic levels?
What are the different trophic levels?First Trophic Level: Autotrophs. ... Second Trophic Level: Primary Consumers. ... Third Trophic Level: Secondary Consumers. ... Fourth Trophic Level: Tertiary Consumers. ... Fifth Trophic Level: Quaternary Consumers.
Which trophic level has the least available energy in kilojoules in this food web?
Which trophic level has the least available energy in kilojoules in this food web? Correct. The amount of energy available decreases up the food chain, so the organisms at the highest trophic level would have the fewest kilojoules of energy available.
Which organism receives the least amount of energy from the producers?
The top consumer of a food chain will be the organism that receives the least amount of energy.
Which trophic level has most biomass?
Answer and Explanation: The trophic level that contains the greatest biomass in most ecosystems is the producers. Producers are organisms that are able to make their own food from sunlight or chemicals. Thus, they have access to 100% of the energy available.
Why is there less biomass at higher trophic levels?
With less energy at higher trophic levels, there are usually fewer organisms a s well . Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Why does the lowest trophic level have the most biomass?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers.
Which trophic level has maximum biomass?
The biomass is maximum in a forest ecosystem because of their size and longevity of trees. Forest ecosystem has formed the most massive and complex ecosystems of the earth.
Answer
The least energy level would be the tertiary consumer because every time energy goes through a level it gets divided by 10.

9. Which term is least specific? A) organism B) community C) population
Answer
Energy used by various organisms varies (decreases) from one tropic level to another. Hence the greatest amount of energy is stored in the first trophic level (plants) and the least amount of energy is stored in the last tropic level.
