I would go with c because its tells you right in there that the ecosystem help who lives around that area.
Answer:
axon; dendrite
Explanation:
A neuron has three main parts. These are axons, dendrites, and a cell body. Synapse is the site of communication between two neurons. The first neuron of a synapse is called the presynaptic neuron (sending neuron) while the second one is called the postsynaptic neuron (receiving). The axon of the presynaptic neuron and the dendrites of the postsynaptic neuron communicate with each other at the synapse as the axon of the first neuron delivers the nerve impulse away from the cell body.
Dendrites function as the receiving or input portions of a neuron. The plasma membranes of dendrites have numerous receptor sites for binding chemical messengers from the presynaptic neuron.
