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.
The first trophic level ofof a food web is almost always made of autotrophic organisms.
The third trophic level is called Tertiary.
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.
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 its food source
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.
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 :)

Plants, algae, and bacteria occupy the first trophic level of an organism.
Crickets are a first order consumer. This means that they consume the organisms at the lowest trophic level which is the producers.
Without specific organisms provided, it is difficult to determine their trophic level. However, plants are typically found at the primary producer level (first trophic level), herbivores at the primary consumer level (second trophic level), carnivores at the secondary or tertiary consumer levels, and decomposers at the final trophic level.
The first trophic level ofof a food web is almost always made of autotrophic organisms.
The 3rd trophic level contains organisms that are primary consumers, often herbivores that feed on producers from the 1st trophic level. These organisms are then consumed by predators at higher trophic levels.
The 4th trophic level is called the quaternary consumer. Organisms at this level feed on tertiary consumers, which in turn feed on secondary consumers, which feed on primary consumers.
Trophic Level
Plants, algae, and bacteria occupy the first trophic level of an organism.
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.
The fourth trophic level is called the quaternary consumer. These organisms prey on tertiary consumers, which in turn prey on secondary consumers, and so on up the food chain.
