Question

differential equations : predator-prey system, need to explain the relationship, pls help!

Answer 1

If x and y cooperate,
then dx/dt increases with increased y and dy /dt increases with increased x.

If they compete for resources, then more x is less y and more y is less x.

-x^2 and -y^2 terms suggest that x and y are harming themselves, perhaps diminishing crucial resources.

These principles should be helpful here.

Answer 2

okay thanks! but for qn 8? T^T

Answer 3

Bed-time for me. Regards.
