Octopus and squid have chemoreceptors on their tentacles. The correct option is the third option.
A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>
<h3>How do excitatory and inhibitory neurotransmitters act?</h3>
Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).
With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

Answer:
Photosynthetic autotroph
Explanation:
Plants, algae/seaweed and some bacteria can use photosynthesis to turn light energy, carbon dioxide and water into glucose and oxygen. The glucose, or sugar becomes the food for these organisms.
Since they can produce their own food, they are called producers, but they are also called autotrophs. "Auto" meaning self, and "troph" meaning nutrition. Therefore, the correct choice is: Photosynthetic autotroph.
