The third trophic level is called Tertiary.
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.
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.
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.
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
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.
Humans.

1st trophic level=flowers,trees,grass & algae. 2nd trophic level=caterpillars,cow,grasshoppers & bettes. 3rd trophic level=humans,birds & frogs 4th trophic level=lions,dogs and snakes

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 :)

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.
