predator-prey relationships like these account for of the transfers in a food
predator- prey relationships
a predator - prey relationship tends to:
o as the population , there is food for . after a slight lag, the population as well.
o as the number of predators , prey are captured. as a result, the population starts to

Explanation:

Step1: Recall predation concept

Predation is a relationship where predators consume prey.

Step2: Answer 1A

In Nebraska, a common predator - prey pair could be a hawk (bird) and a mouse (instead of bird/fish which is a bit general). A more specific and common pair in Nebraska habitats.

Step3: Answer 1B

A well - known predator/prey pair from anywhere in the world is lion and zebra.

Step4: Analyze predator - prey population dynamics

When prey population declines, there is less food for the predator. After a slight lag, the predator population declines as well. As the number of predators declines, fewer prey are captured. As a result, the prey population starts to increase.

Answer:

1A. Hawk/mouse
1B. Lion/zebra

1. As the prey population declines, there is less food for the predator. After a slight lag, the predator population declines as well. As the number of predators declines, fewer prey are captured. As a result, the prey population starts to increase.
