Which trophic level absorbs the greatest amount of energy?
Autotrophs (plants) use 1-3% of sun light and store it in the form of food to the herbivores. So grestest amount of energy is present in autotrophs….Question : Trophic level of food chain having greatest amount of energy is.

How much energy is transferred to the next highest trophic level?
On average, only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next. This is known as “the 10 percent rule” and it limits the number of trophic levels an ecosystem can support.
At which trophic level is maximum energy available and why?
Explanation: At T1, producers, which make food, are present, and hence they are at the bottom of the trophic levels. As they get energy directly from the sun, they have the maximum energy.
Which gets the greatest amount of energy?
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy.
Which trophic level has both the greatest amount of energy and the greatest amount of biomass?
producers
The trophic level that contains the greatest biomass in most ecosystems is the producers.
What are higher trophic levels?
The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.
Which trophic level has the greatest 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. These include things like grass, trees, and flowers.
At which trophic level is minimum energy available?
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.
Which is the first trophic level in a food chain?
The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
What trophic level has the least energy?
tertiary consumers
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.
What level has the greatest 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.
Which ecosystem has the greatest amount of energy overall the least amount?
The area at the bottom of the pyramid of energy represents the greatest amount of energy in an ecosystem. As the energy passes from producers to consumers, less is available at each successive trophic level.
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 trophic level must have more of than others?
There are more autotrophs than heterotrophs, and more plant-eaters than meat-eaters. Each level has about 10% less energy available to it because some of the energy is lost as heat at each level. Although there is intense competition between animals, there is also interdependence.
How much energy would get to the trophic level?
The ten percent rule states that each trophic level can only give 10% of its energy to the next level. The other 90% is used to live, grow, reproduce and is lost to the environment as heat. All energy pyramids start with energy from the Sun which is transferred to the first trophic level of producers.
What amount of energy will each trophic level contain?
The amount of energy in one trophic level of a lake ecosystem is 1000 Joules (J). The next highest trophic level contains 190J. The consumed energy between these trophic levels is 650J and the assimilated energy is 450J. What are the consumption, assimilation, and net production efficiencies from the lower to the higher trophic level?-15%, 14%, 24%
