Humans and Bacteria are considered 4th Level consumers.
A tertiary consumer e.g. Human.
Basically a carnivore that eats other carnivores.

All sources of energy come from the sun. Autotrophs make their own energy through photosynthesis by collecting energy from the sun. When an organism (herbivore) at the next trophic level eats them they only get approximately 10% of the energy that the first organism had. When another organism eats the animal that ate the plate they only get approximately 10% of the energy of what that animal got from the previous animal. So this animal only got 1% of the energy from the sun. If more trophic levels existed they would only get 10% of this 1% so would not get enough energy (approximately 0.1%) so is why trophic levels are limited.
The trophic level a chicken is at is the secondary consumer level. Since they are omnivores, they eat other animals and plants but also get eaten themselves by other predators.
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.
if both organisms repoduce an offspring every 12 hours then they would have the same number of offspring neither would be greater.
The smallest unit of an organism would be the epithelial cell I think... The function would be to protect or cover the body, I don't know okay!
primary producer
I would assume it to be the amount of mass in a specific trophic level. Thus, the trophic mass pyramid.
no
if trophic level is a food chain then a food pyramid would be opposite.
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 third level.
Yes. Plants would be the first trophic level, insects that eat the plants would be the second, and the spiders that eat the insects would be the third.
A vampire bat would most likely be on the top trophic level. This level would be tertiary consumers and is because vampire bats don't have any predators.
There are limits because remember that it's usually only 10% of energy from one level that gets passed to the next trophic level so eventually you basically have nothing more to pass that would be of any use.

Third trophic level
Detrivores are the organisms break down and feed on deed organic matter. the can be found in the second trophic level, along with herbivores.
