Why do different trophic level have different amount of energy?
Some energy transferred at each successive trophic level enters the environment as heat.
Loss of energy in the food chain limits the amount of what?
Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
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.
What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?

What does a pyramid of energy show about the amount of energy available at different trophic levels of food chain?

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.
What happen to the amount of biomass from the bottom to the top of pyramid?
In a biomass pyramid, the amount of biomass typically decreases from the bottom to the top. This decline occurs because energy is lost at each trophic level due to factors such as metabolic processes and heat loss, which means that less energy is available to support higher trophic levels. As a result, fewer organisms can be sustained at each successive level, leading to a lower biomass at the top of the pyramid compared to the base.
A diagram that compares energy use among trophic levels?

What would biomass tell us that a pyramid of numbers wouldn't?
A pyramid of numbers will only tell you the amount of organisms at each trophic level. A Biomass pyramid ignores the amount of organisms in favour of their biomass (dry weight) which in turn represents the amount of energy available at each trophic level.
A biomass pyramid differs by showing the at each trophic level.?
A biomass pyramid illustrates the amount of organic material, or biomass, present at each trophic level in an ecosystem. Typically, it shows that producers (like plants) have the highest biomass, followed by primary consumers (herbivores), secondary consumers (carnivores), and so on, with each successive level having less biomass. This structure highlights the energy flow and efficiency within an ecosystem, as energy is lost at each trophic level due to metabolic processes. Ultimately, the pyramid shape emphasizes the diminishing biomass and energy available to higher trophic levels.
What happens at every ascending level of the pyramid of energy?
As energy flows through each ascending level of a pyramid of energy, some energy is lost as heat due to metabolic processes like respiration and movement. This results in a decrease in available energy at each higher trophic level. Thus, the amount of energy available to organisms at higher trophic levels becomes progressively smaller.
Why is the amount of available energy different for each type of organisms on a food chain?
The amount of available energy differs among organisms in a food chain due to the inefficiencies of energy transfer between trophic levels. Typically, only about 10% of the energy from one level is passed on to the next, as much is lost through metabolic processes, heat, and waste. Consequently, primary producers (like plants) have the most energy, while higher-level consumers (like predators) receive significantly less. This results in fewer organisms and less biomass at each successive trophic level.
