The respiratory centers that control your rate of breathing are in the brainstem or medulla. The nerve cells that live within these centers automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals.
Autotrophic organisms are capable of synthesizing their own food and nutrition by harnessing sunlight and water.
Along with the entire kingdom Plantae and the following organisms are autotrophs:
Algae
Cyanobacteria
Seaweed
Phytoplankton
Fungi are heterotrophs, particularly of saprophytic nature. This means that they release enzymes on organic matter. These enzymes digest the organic matter into nutrients that the fungus can then utilize.
