Autotrophs are characterized by their ability to produce their own food; parasites, saprophytes, and pathogenic (disease-causing) organisms do not have this ability. Chemosynthetic ones, however, can through the conversion of one or more carbon-containing molecules into organic matter.
The correct answer is reuptake.
The reabsorption of a neurotransmitter by a neurotransmitter transporter situated along the plasma membrane of an axon terminal or glial cell after it has done its activity of conducting a neural impulse is called reuptake.
The process of reuptake is essential for usual synaptic physiology as it permits for the recycling of neurotransmitters and monitors the neurotransmitter level in the synapse, thus, monitoring the duration of the signal resulting due to the discharge of the neurotransmitter.
Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics. Phylogenetic trees compare organisms over evolutionary time and the amount of change that has occurred over time to figure out the relationships.
