If the 1st trophic level has 10000 kilocalories of energy how much energy will be available for trophic levels 2-4?
One million calories .
If a biomass pyramid contains 400 kilograms of wheat at its base how many kilograms of human tissue would exist at the fourth trophic level?
If a biomass pyramid contains 400 kilograms of wheat at its base, 4 kilograms of human tissue would exist at the fourth topic level.
Why do food chains not exceed 4 links?
because the way a food chain works is energy is transferred between trophic levels, but as you move up each trophic level, about half of the energy is lost, which means when you get to the fourth trophic level, only about 10% of the original energy is remaining, so adding another level would mean that the creature would have to consume 10 times as much of its respective prey to get the energy equivalent of 1 of the creatures at the first trophic level. so in other works, energy consumption would be too inefficient
Why do most food chains do not extend beyond the 4 th trophic level?
The amount of energy transferred from each trophic level to the next is around 10%. This is a tiny amount. By the 4th level, there is so little energy available that it is not possible (in most cases) to support a 5th level. Generally, where a 5th level exists, the organism isn't on the 5th level for every chain it is included in. Example: Primary producer (1st level) :100 Joules Primary consumer (2nd level) : 10 J Secondary consumer (3rd level) : 1 J Tertiary consumer (4th level) : 0.1 J
What is the connection between cellular respiration and the number of trophic levels possible in any ecosystem?
Cellular respiration releases energy from food molecules for use by organisms. As energy transfers between trophic levels are not 100% efficient, a significant amount of energy is lost at each level. This limits the number of trophic levels in an ecosystem, since there is a decrease in available energy as you move up the food chain.
What is the trophic level of the bird?
The trophic level is where an organism falls on the food chain. Most birds fall on the highest level, trophic level 4.
What is a trophic level and what determines an organism's trophic level?
Trophic level is a group of organisms that occupy the same position in a food chain. An organisms trophic level is determined by its position in a food chain against all levels Producers(Level 1), Herbivores(Level 2), Predators(Level 3), and Carnivores as Level 4 or 5.
What trophic level is a human who eats the Moray Eel?
Human trophic level varies. If the individual in question ate only moray eels (who are independently about a trophic level of 4, on account of being mostly piscivorous) then I imagine the human would be at a similar level. If the eel made up a part of an otherwise omnivorous diet, then I expect the person's trophic level to be closer to 2.5-3.0
If the 1st trophic level has 10000 kilocalories of energy how much energy will be available for trophic levels 2-4?
One million calories .
Why are there usually never more than 4 trophic level in a food web?
Energy transfer between trophic levels is not very efficient, leading to a loss of energy as it moves up the food chain. This limits the number of trophic levels that can be supported in a food web. Additionally, with each higher trophic level, there is a decrease in available energy and biomass, making it difficult to sustain more than 4 trophic levels.
If a biomass pyramid contains 400 kilograms of wheat at its base how many kilograms of human tissue would exist at the fourth trophic level?
If a biomass pyramid contains 400 kilograms of wheat at its base, 4 kilograms of human tissue would exist at the fourth topic level.
Tiger trophic level?
According to the list below, tigers would be a trophic level 4 or Top Level Carnivore. Trophic levels are:1st/bottom level) Producers: Organisms that produce their own food such as plants.2nd level) Consumers: These are animals that are herbivores, they eat plants and no meat.3rd level) Secondary Consumers: These are primary carnivores and only eat meat.4th/top level) Tertiary Consumers: These are the creatures at the top of the food chain because they have no predators.
Term for each step in the transfer of energy and matter within a food chain?
For each step in the food chain, would be classified as a Trophic Level.For example of a 4 level chain.Grass -> Grasshopper -> Frog -> Snake
What trophic level do swordfish belong to?
Swordfish are primarily classified as apex predators, which places them at the top of the marine food chain. They typically inhabit the pelagic zone of the ocean and feed on a variety of prey, including squid, fish, and other marine organisms. This positions them at a high trophic level, generally around level 4 or 5, depending on the specific ecosystem.
Why do food chains not exceed 4 links?

Number of trophic levels in ecological pyramid?
there can be any number of trophic levels, but usually 4-5
