all organisms feed on different levels. these are called trophic levels. eg: the grass outside can be fed on by cows and horses or basically herbivores. therefore, herbivores are said to feed on one trophic level. likewise, carnivores all feed on another trophic level but omnivores can feed on two because the consume both meat and plants

Organisms at the first trophic level are called?
Producers make up the first trophic level. A trophic level is each step in a food chain or food web is called a trophic level.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
In a food web what organism make up the first trophic level?
The first trophic level ofof a food web is almost always made of autotrophic organisms.
What would biomass tell us that a pyramid of numbers wouldn't?
A pyramid of numbers will only tell you the amount of organisms at each trophic level. A Biomass pyramid ignores the amount of organisms in favour of their biomass (dry weight) which in turn represents the amount of energy available at each 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.
What animal would be at the 2nd trophic level?
The group of organisms that occupy the second trophic level of an ecosystem is the herbivores. The herbivores eat the plants in the first trophic level and are then called primary consumers. -Gallo :)
What is the lowest trophic level?
The first trophic level is a primary producer. The main purpose of these organisms is to produce things for other organisms to use.
What group of organisms the second trophic level of an ecosystem?
The group of organisms that occupy the second trophic level of an ecosystem is the herbivores. The herbivores eat the plants in the first trophic level and are then called primary consumers. -Gallo :)
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
What are organisms in the lowest trophic level of an ecosystem?
Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
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.
Organisms at the first trophic level are called?
Producers make up the first trophic level. A trophic level is each step in a food chain or food web is called a 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%
Why are the numbers of trophic levels limited?
At each trophic level in a food chain, a large portion of the energy is utilized for the maintenance of organisms which occur at that trophic level and lost as heat. As a result of this, organisms in each trophic level pass on less and less energy to the next trophic levels, than they receive.
An organisms trophic level is a measure of its ability to release nitrogen into the atmosphere?
No, Trophic level is the level it is in in the food chain depending on its habitat.
What is the crickets trophic level?
Crickets are a first order consumer. This means that they consume the organisms at the lowest trophic level which is the producers.
