The food chain.
a transfer of chemical nutriet and energy
Without producers the consumers would have nothing to eat and wouldn't have any energy. Producers get energy directly from the sun. Consumers can't make their own food or energy without eating something else.
This is not called anything, as it is not possible. A food web shows the transfer of energy from one organism to the other, not just what kills what. For example, a food web will generally show arrows going from a producer, to a primary consumer, to a secondary consumer, and looping back with a decomposer, such as a worm.
Birds do not produce energy from light, so they cannot be producers. All birds are consumers.

Consumer
I think it is called a consumer, producers obtain energy from the sun(???)
Primary Consumer - an organism that gets its energy from producers (plants). These are often called herbivores.
Consumer because a consumer eats plants and animals for energy Producers create their energy through photosynthesis
The transfer of energy is called Energy Transfer
Not all the energy from a producer transfer to a secondary consumer because some of this energy is lost along the way.
consumer to consumer
producers
Producers Consumer Decomposer
They make their own energy, instead of consuming another consumer for their energy.
An organism that cannot make its own food is called a consumer. Organisms that make their own food are called producers. Consumers must create energy from eating producers or other consumers.
