Question

Which of the following is a nonrenewable resource for a species of predatory bird?

a.nest sites

b. O2

c. prey

d. water

e. > 1 of the above

Answer 1

b. O₂ c. prey d. water
These resources, especially Oxygen and Water are renewable, and with respect to the scale and use of the predatory bird, these resources are considered limitless due their abundance. For prey, we can consider the term 'renewable' to signify that since the biological prey shows the ability to procreate and create offsprings, if an optimal number of their population escapes and/or is kept alive, they can continually replenish their population with successive generations thereby providing a seamlessly unending supply of prey for the species of predatory bird.

Out of the following, the one which is is a nonrenewable resource for a species of predatory bird is:
a. nest sites - this is because nest sites, their location, proximity to essential resources, the level of safety offered from higher predators or forces of nature. make them a very rare and selective find, which raises competition within the species because all predatory birds look for such sites, occupy one of them upon finding them, and once successfully inhabited with offsprings, then taking the nest is not possible without an attack by the incoming predatory bird.
