Question

10. Consider predator-prey oscillations, an interesting example of population dynamics. Define and describe using real examples. Finally discuss how humans could possibly influence this phenomenon.

Answer 1

- Predator-prey cycles are among the major wonders of natural frameworks: the populace sizes of predators and their prey, for example foxes and rabbits, are every now and again subject to normal motions.

- Predator-prey cycles depend on a taking care of connection between two species: if the prey species quickly duplicates, soon thereafter the quantity of predators increments - until the predators in the end eat such a large number of prey that the prey populace goes down once more. Before long a short time later, predator numbers moreover decline because of starvation. This thus prompts a fast increment in the prey populace and another cycle starts.

-  populalation dynamic alludes to how the quantity of people in a populace changes after some time.  the components that influence populace elements since they are keen on themes, for example, protection of imperiled species (for instance, the Florida jaguar) and the executives of fish and natural life.

- the passenger pigeon, which was once one of the most numerous birds on Earth, went globally extinct in 1914 due to overhunting and habitat loss.

- The reliance of people on nature has come into center as the human populace keeps on developing, assets reduce and creation innovation deteriorates – compromising human well‐being on a worldwide scale. Various past models portray human populace elements, corresponding to a huge number of various elements. In any case, there are no steady driving variables of human demography through history, which makes foreseeing future changes additionally testing.
