What is trophic levels?
A group of organisms that occupy the same position in a food chain.
Why do biologists measure the number of trophies levels in an ecosystem measure the number of trophic levels in an ecosystem?
To check its stability and health
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.
What is flow of energy in ecosystem?
Energy flows from one trophic level to the next (Producer->Primary Consumer->Secondary Consumer). Energy transfer becomes less efficient as it's being transferred; seeing as it is partly used by the organism for metabolic processes.
What are harmful levels of ozone?
The harmful levels are below 220ppm. It falls below that level and it is called ozone hole.
What is trophic levels?
A group of organisms that occupy the same position in a food chain.
Why do toxins accumulate at such high levels in carnivores?
The biomass at any given trophic level is accumulated from a much larger toxin-containing biomass ingested from the level below.
What are some secondary consumers in the tundra?
Penguins, arctic fox, seals, snowy owls, terns, harlequins, and gulls.
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.
Are biomass and trophic level related?
Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
If you follow the longest food chain in the food web below from grass to owl how many tropic levels are there?
four
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.
Why do biologists measure the number of trophies levels in an ecosystem measure the number of trophic levels in an ecosystem?
To check its stability and health
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).

What does a consumer in a food chain depende on for energy?
A consumer depends on the trophic level below it for energy.

A consumer depends on the trophic level below it for energy.
