Primary producers are the bottom most trophic level.
Each step in a food chain or food web. Autotroph are always trophic level 1.
Trophic level efficiency is the ratio of production of one trophic level to the production of the next lower trophic level. This efficiency is never high.
The first trophic level, which are the producers
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 giraffe occupies the second trophic level because it is a primary consumer. Giraffes are herbivores so they feed off of the producers in the first trophic level.
Each step in a food chain or food web. Autotroph are always trophic level 1.
Same concept as the trophic level EXCEPT you are only counting the consumers.
The energy is transferred from a lower trophic level to a higher trophic level when resources are consumed.
Producers aren't really a trophic level because they are producers. A trophic pyramid consists of consumers and the levels of energy between them. Since producers don't actually eat anything they are on the bottom.
algea
No.
Scavengers are on every trophic level
The trophic level is where an organism falls on the food chain. Most birds fall on the highest level, trophic level 4.
they are tertiary consumers. the first trophic level.
Their trophic level is primary consumer.
Third trophic level. It eats insects.
In which trophic level are all plants found?
