What is trophic levels?
Trophic levels refer to the hierarchical levels in an ecosystem where organisms are grouped based on their feeding relationships and energy transfer. Producers, such as plants, make up the first trophic level, followed by herbivores, then carnivores or omnivores. Each trophic level represents a transfer of energy from one group of organisms to another.
How are trophic level efficiency measured?
Trophic level efficiency is typically measured by calculating the amount of energy transferred from one trophic level to the next. This is done by analyzing the ratio of energy present in the biomass of one trophic level compared to the trophic level below it. The efficiency of energy transfer between trophic levels is usually around 10%, meaning that only around 10% of energy is transferred from one trophic level to the next.
What is the energy pyramid made up of?
The energy pyramid is made up of trophic levels, which represent the different levels of organisms in an ecosystem based on their position in the food chain. It shows how energy flows through an ecosystem, with each trophic level receiving energy from the level below it and transferring some to the level above. The pyramid reflects the decreasing energy available at each successive trophic level due to energy loss through metabolism and heat.
Why do biologists measure the number of trophies levels in an ecosystem measure the number of trophic levels in an ecosystem?
To check its stability and health
How does the 10 percent rule relate to the biomass pyramid?
As the levels progress upward in a pyramid form, only 10% of the energy level below can be transfered as energy to the next level. Using the lowest level as having 100%, the next level only has 10% of that 100% to use for energy. The third level will have 10% of 10% of that 100% to use for energy. Because there is only so much at each level to use, the number of animals and plants become smaller. At most there will be 3 levels. A very few will reach 4 levels.

What percentage of energy is transferred to next trophic level from the lower trophic?
Typically, about 10% of energy is transferred from one trophic level to the next in an ecosystem. This is known as the "10% rule," which reflects the energy loss that occurs due to metabolic processes, heat production, and other factors. Consequently, higher trophic levels receive significantly less energy than those below them, leading to fewer individuals and biomass at the top levels of the food chain.
Why do toxins accumulate at such high levels in carnivores?
The biomass at any given trophic level is accumulated from a much larger toxin-containing biomass ingested from the level below.
Explain how the biomass of a species is limited by their tropic level?
The biomass of a species decreases with increasing trophic level due to energy loss along the food chain. Each trophic level consumes energy and nutrients from the level below, resulting in a smaller overall biomass at higher trophic levels. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next.

What are some secondary consumers in the tundra?
Penguins, arctic fox, seals, snowy owls, terns, harlequins, and gulls.
Are biomass and trophic level related?
Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
Why can each trophic level support only about one tenth the amount of the living tissue of the level below?
This is because energy is lost at each trophic level. The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
Why can each trophic level support only about one tenth the amount of living tissue of the level below?
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
