In which trophic level are all plants found?
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.
The first trophic level, which are the producers
They are omnivorous meaning they eat all things (plants and animals)
Producers are plants, and are found on the first trophic level. Consumers are normally animals, and they comsume the plants or other animals that have eaten the plant before them. These consumers are found on the second trophic level and upwards, depending on how the consume the energy that originated from the plant.
The bottom level which contains plants has the most energy. This is because they get their energy directly from the sun while other animals get it from plants themselves, or other animals. Animals cannot absorb 100% of the energy when they eat plants so the level of energy degrades all the way to the top of the food chain. Each animal gets less and less % of the energy the plant had in the first place.
It is the 2nd consumer on the trophic level! :)
Animals at the second trophic level that eat flowers are the herbivores. These animals eat both plants and flowers of different plant types.
Decomposers will break down dead animals and plants leaving free the nutrients or minerals necessary for plants to grow.
Mosquitos can be of many different trophic levels, as they consume the blood of animals from multiple trophic levels.
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.
Animals, human beings
