Why are there fewer organisms in the higher trophic levels than the lower trophic levels?

the temperature is higher and in generally the conditions of life is much easier... There are also many atmospheric and oceanic phenomena participating in making the environment much more friendly than any other geographic level. and of course, cause they're near me :)

β 9y agoThe biomass is the smallest in the highest trophic level. This is because only 10-20% of energy is passed from one trophic level to the next. Most of the energy is lost during desperation and activity.
Only 10% of the biomass is passed on to the next level because the lower level needs to grow and reproduce.

What can you conclude about a ecosystem with many trophic levels?
it is a stable ecosystem
How are energy pyramids and trophic level alike?
The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2). See links below:
Why are there fewer organisms higher on the energy pyramid?
The higher you are on the pyramid the less energy you get, so it takes a lot of stamina and endurance to be at the top.
Which classification group fewer organisms in it family or an order?
It goes: Domain, kingdom, phylum, class, order, family, genus, species; with domain with the most organisms, and species with the fewest. Therefore there are fewer organisms in a family.
True or False If two modern organisms are distantly related in an evolutionary sense then one should expect that they should share fewer homologous structures than two more closely related organisms?
True, they should share fewer homologous structures than two more closely related organisms.
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.

Why do you see fewer and fewer animals at each higher trophic level?
Only about 10 percent of energy at any given level will make it to a higher one.

Why do food chains rarely have more than 5 trophic levels?
Energy is lost to the surroundings as the food chain goes from one level to the next, so there are fewer organisms at each level in the food chain. Eventually there would be no animals left for another animal to eat eg: grass----->rabbit----->fox----->? 100 10 1
Is it true that when cells move into higher organization levels in an organism they must work with fewer diffrent types of cells?
false
Why some of these ecological pyramids are upright while others are inverted?
It is mainly presented in a graph form and deals with the number of individuals in per unit area. It deals with multiple trophic levels with producers forming the base and the top carnivore occurs at the tip. It is upright in shape which means that the base is larger in size and it decreases as we move upwards. The numbers of organisms at the higher level are less in number as compared to the organisms which occur at the lower levels. The producer organisms are the largest in number. They support the herbivore and carnivore which are fewer in the number. In the land the grass is eaten by the grasshopper. The grasshopper is eaten by the frog and the frog is eaten by the snake. Ultimately, the snake is eaten by the peacock. In the other aquatic food chain, the phytoplankton is eaten by the zooplankton. The zooplankton is eaten by the small crustaceans. The small crustaceans are eaten by the predator insects. The predator insects are eaten by the small fish. The small fish are eaten by the large fish. This is followed by the kingfisher. The kingfisher is least in number. At the higher trophic levels the number of pyramids is usually smaller in size. The higher organisms are dependent on the lower organisms for their food. When the energy is transferred from one level to the other 90 percent of it is wasted and only 10 percent of it is utilized. Sometimes the single sized tree provides food to the number of herbivore like birds which support a large number of ecto parasites. This is an inverted pyramid. The small sized birds are eaten by the eagles which are fewer in number. They form a spindle shape pyramid.
Why are there fewer higher level consumers in an ecosystem than first level consumers?
As you may already know, each trophic level survives off of the trophic level below it. Energy is lost between trophic levels- to be specific, about 90% is lost in heat, excretory products etc. To make things easier, let me use an example. The first trophic level, producers, consists of organisms like plants. They receive 100% of their energy from the Sun. Herbivores, consume plants, but only 10% of the energy is passed on, making it less efficient. As the trophic levels increase, lesser and lesser energy is available to the higher trophic levels. Resultantly, there simply isn't enough energy at the higher trophic levels, and hence, a smaller number of organisms are supported. I hope this helps you! (:
Why are there always fewer tertiary consumers than producers in an ecosystem?
Only 10% of energy is moved from one trophic level to another in the biomass consumed. So, at the tertiary level there is only enough food energy to support a limited number of consumers. As the number of trophic levels increases, you also have to be more adapted so you can become a predator of the trophic levels below you. If for example there was a species that were above humans, they would have to be smarter, quicker and more adapted - which gets progressively harder.
