Wetlands include swamps, marshes, bogs, riverbanks, mangroves, floodplains, rice fields—and anywhere else, according to the U.S. Environmental Protection Agency (EPA), that saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities there. They are widespread in every country and on every continent except Antarctica. If all the world’s wetlands were put together, they would take up an area one-third larger than the United States.
Environmentalists, biologists and others concerned about the health of the planet and its inhabitants recognize the key role wetlands play in life on Earth. The EPA points out that, besides containing a disproportionately high number of plant and animal species compared to other land forms, wetlands serve a variety of ecological services including feeding downstream waters, trapping floodwaters, recharging groundwater supplies, removing pollution and providing fish and wildlife habitat. Wetlands can also be key drivers of local economies, given their importance to agriculture, recreation and fishing.

Explanation:
Yes! Neurotransmitters are chemical compounds that are produced from the terminal of a neuron and bound by specific protein in the adjacent neuron where it helps to transmits a nerve impulse.
Neurotransmitters can be:
- Excitatory such as acetylcholine that cause muscle to contract and gland cells to produce secretions (i.e neuron will fire)
- Or inhibitory such as glycine which inhibits the contractions of muscles (i.e neuron did not fire)
Thus, neurotransmitters do all of the functions provided
