Because of species. For example, some birds, eat some snakes, but half of the time, the snakes are poisonous or so, and again, some birds can detect the poison, some cant. I hope this helped.
If the first layer has 100 members, the second layer can only be 10% so 10 members can be supported, the last layer will be 10% of that or 1.
Mosquitos can be of many different trophic levels, as they consume the blood of animals from multiple trophic levels.
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.
There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.
A rain forest ecosystem can support 3-4 trophic levels.
The most accurate method is to use a pyramid of energy to show the transfer of energy between trophic levels
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
there can be any number of trophic levels, but usually 4-5
Yes, if you mean in terms of food chains and trophic levels, etc.
Trophic levels play a significant role in the transfer of energy within food chains and food webs. Each organism has a position n the trophic level and energy is transferred through succession.
Food webs are made from many food chains. A trophic level in every food chain is a stage where energy is transferred from a lower level to the next higher level. Trophic levels include producers, consumers (primary and secondary), decomposers.
Its called biomagnification - sorry i spelled it wrong the first time
Mosquitos can be of many different trophic levels, as they consume the blood of animals from multiple trophic levels.
Food chains are short because a lot of energy are expended at the trophic levels. Also it's because as we consider the many losses of energy such as heat and undigestable parts such as cellulose, hooves, and antlers. There aren't many energy to keep and pass on to the next level. Therefore, food chains contain usually 3-5 levels.
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.

The food web is made up of different levels labeled as trophic levels. Chimpanzee's belong on the 3rd trophic level.
A group of organisms that occupy the same position in a food chain.
