Consider a simple marine ecosystem with orcas, otters, sea urchins and kelp. The kelp grows and is eaten by sea urchins which are eaten by otters which are in turn eaten by orcas. But suddenly, otters become the new "in" exotic pet and their population is removed. What effect would their removal have on the rest of the species in the ecosystem?
Orca population would decrease in number due to losing their main source of food. Sea urchins would explode as their main predator was removed. This increase in the population of sea urchins would lead to the amount of kelp decreasing.

What is the purpose of inhibition in the nervous system? What might be some consequences that come from a lack of inhibition?
Without inhibition, our nervous system would not be as specific. Nerves in, for example, our fingers would have a larger area in which they could register the touch. Inhibition by overlapping receptive fields in our nerves increases the specificity by which we can identify where our touch receptors are being activated.
