An otherwise healthy student in your class is infected with EBV, the virus that causes infectious mononucleosis. The same student had already been infected when she was a child, and she had merely experienced a mild sore throat and swollen lymph nodes in her neck. This time, though infected, she does not get sick. 

Her immune systemʹs recognition of this infection will involve which of the following?

Predator has carrying capacity

Following some observation are given

The number of prey, N, increase at low predator densities, P, and decrease at high predator densities

Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators

 Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators

Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators

Which of the above observation are true?
