Trophic LevelsPond PowerPre-Field expedition Lesson | |
Below are instances of the trophic level in one particular food chain: | |
![]() | Grass to produce its very own food with photosynthesis. That is aprimary producer at the bottom the the food chain. Primary producers room the 1st trophic level. |
![]() | Grasshoppers room herbivores the eat grass. Therefore, they are one trophic level higher than grass. Castle are considered primary consumers. Major consumers room the second trophic level. |
![]() | Toads eat grasshoppers. Therefore, they space one trophic level higher than grasshoppers. Castle are taken into consideration secondary consumers. Secondary consumers are the 3rd trophic level. |
![]() | Hawks are carnivores the eat toads. Because of this they are one trophic level greater than toads. Castle are thought about tertiary consumers. Tertiary consumers are the fourth trophic level. Tertiary consumers tend to be in ~ the top of the food chain. They have few, if any, predators. |
![]() | Bacteria, fungi and other biology feed off of dead matter. These organisms are recognized as decomposers. You are watching: Is grass a producer consumer or decomposer They convert the dead matter back into nutrients. Decomposers room at both the beginning and also end the the food chain. Therefore, decomposers room not assigned a trophic level. |
