Answer:
NEUROTRANSMITTER
Explanation:
Imbalances with neurotransmitter results in depression, anxiety and other mood disorders. Examples of neurotransmitters that affects mood are Serotonin, Dopamine, GABA and Norepinephrine.
The Acetylcholine and norepinephrine are known as the excitatory neurotransmitters and the dopamine, serotonin, and GABA are known inhibitory neurotransmitter.
A Neurotransmitter influences behaviour by affecting neurons in a specific portion of the brain.
The spiral usually begins with an increase in demand. The direct effect of this increase is that the producers (of commodities) raise prices to continue to make a profit. It usually begins with a rise in production costs.
Human activities that increase the greenhouse effect are burning of fossil fuels and reducing the amount of trees on our planet increase the gases of the greenhouse affect. also cows release the gas methane when they fert which is a greenhouse gas.
If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
