Which tropic level in a community has the most energy available?
The trophic level of producers (photosynthetic organisms) has the most available energy in a biologic community. As a general (but not absolute) rule, every trophic level above this has 10% as much available energy as the level below it; primary consumers have 10% as much as producers, secondary consumers 1%, tertiary consumers .1%.
How much energy is available at the third tropic level of an energy pyramid if 1000 kcal is available in the first level?
In an energy pyramid, only about 10% of the energy from one trophic level is available to the next level. Therefore, if 1000 kcal is available at the first trophic level, approximately 100 kcal would be available at the second trophic level. At the third trophic level, only about 10% of that energy would be available, resulting in roughly 10 kcal.
If 100 percent of the energy is available at the trophis level what percentage of the total energy is available at the highest trophic level?
Only about 10% of the energy is transferred between trophic levels, so if 100% is available at the lowest trophic level, then only about 10% of the original energy is available at the highest trophic level.
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.
What percent of the energy available within on trophic level is transferred to organisms at the next trophic level when they are eaten?
1%
What energy is available each step up the pyramid?
As you move up the energy pyramid from trophic level to trophic level, around 10% of the energy is transferred from one level to the next. This means that only 10% of the energy is available to the next trophic level, with the remaining 90% being lost as heat or used by the organism for its own metabolism.
Is about 50 percent of the energy available within one trophic level transferred to the next trophic level?
No. About TEN (10) percent of the energy available within one trophic level is transferred to the next trophic level the rest of it is used to grow and develop, except in plants because plants use 100% or close to 100% of the sun's energy to grow and develop.
How much energy would be available at the third trophic level if the first trophic level has 300000 kilocalories of available energy and the loss rate between trophic levels is 90 percent?
If the first trophic level has 300,000 kilocalories and there is a 90 percent loss of energy between trophic levels, then only 10 percent of the energy is passed on to the next level. Therefore, the second trophic level would have 30,000 kilocalories (10% of 300,000). Applying the same loss rate, the third trophic level would have 3,000 kilocalories (10% of 30,000).
Why does only a small fraction of the energy at one trophic level become available to the next trophic level?
About 10% of the energy in the lower trophic level is passed to the next higher level. The 80% of energy that is left is used by that lower level for life processes or is lost as waste.
If the 1st trophic level has 10000 kilocalories of energy how much energy will be available for trophic levels 2-4?
One million calories .
Where is the energy in the trophic level lost to?
Energy in the trophic level is lost through heat production during metabolic processes such as respiration, movement, and growth. This heat is released into the environment, resulting in a decrease in available energy for the next trophic level.
