What trophic level is the smallest?
The lowest trophic level is primary producers, such as algae and phytoplankton, which generate their own energy from the sun via photosynthesis.
Which is the smallest biomass?
The smallest of all, Prochlorococcus, is just 0.5 to 0.8 micrometres across.
What part of the trophic level has the least energy or biomass receives?
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.
Do lower trophic levels have more biomass?
Trophic Levels and Biomass Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.
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.
What organisms have the least biomass which has the least energy?
The trophic level that has the least biomass is usually the tertiary consumers.
Which trophic level has maximum biomass?
Solution : Biomass refers to the amount of living organic matter. Forest ecosystem have the maximum biomass, because it includes organisms of all trophic levels as compared to pond, lake or grasland ecosystem.
Which trophic level has the largest 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.
Why the fourth trophic level has the least biomass?
With less energy at higher trophic levels there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels but their smaller numbers result in less biomass.
Why is there less biomass at the top of the energy pyramid?
The top level of an energy pyramid has the fewest organisms because it has the least amount of energy. Eventually there is not enough energy left to support another trophic level; thus most ecosystems only have four trophic levels.
Who has the most biomass?
Plants Plants make up the overwhelming majority of biomass on Earth. There are 320,000 species of plants, and their vital photosynthetic processes keep entire ecosystems from falling apart.
What ecosystem has the largest biomass?
The forest ecosystem has the largest total biomass, which represents about 70% of the whole terrestrial ecosystem.
What has the most biomass?
Plants Plants make up the overwhelming majority of biomass on Earth. There are 320,000 species of plants, and their vital photosynthetic processes keep entire ecosystems from falling apart.
Why is biomass less at each trophic level?
Only approximately 10 % of the biomass from each trophic level is transferred to the level above it. This is why the pyramid of biomass gets smaller, as there are less organisms as we go higher up the trophic levels. Losses of biomass are due to: Not all the ingested material is absorbed, some is egested as faeces.
How do you find the biomass of a trophic level?

Which group has the least biomass?
Answer and Explanation: The trophic level that has the least biomass is usually the tertiary consumers.
Which trophic level has the greatest biomass quizlet?
Explanation. When the trophic level increases, then the biomass would decrease. In this case, the trophic level which contains the greatest biomass is the producers, which is the lowest trophic level. This means that there are more producers than the first level consumers.
Why does the first trophic level has the most biomass?
The first trophic level has the most biomass because it has the most energy according to the 10% rule.
Why does the fourth trophic level have the least biomass?
With less energy at higher trophic levels there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels but their smaller numbers result in less biomass.
Where is the greatest amount of biomass found?
We find that the biomass of plants dominates the biomass of the biosphere and is mostly located on land. The marine environment is primarily occupied by microbes, mainly bacteria and protists, which account for ≈70% of the total marine biomass. The remaining ≈30% is mainly composed of arthropods and fish.
What is the level with 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 group has the most biomass?
Plants make up the overwhelming majority of biomass on Earth. There are 320,000 species of plants, and their vital photosynthetic processes keep entire ecosystems from falling apart.
What is the largest trophic level by biomass?
Answer and Explanation: The trophic level that contains the greatest biomass in most ecosystems is the producers.
