Question

according to the pika lab, which two factors would influence pika density the most?
increase in predators and high nutrition
high snow pack and high nutrition
high elevation and increase temperatures
decrease in predators and high nutrition

Explanation:

Pikas are small mammals. A decrease in predators means less threat to their survival, allowing more pikas to thrive. High - nutrition resources ensure they have enough energy for growth, reproduction, etc. An increase in predators would reduce their numbers, high snow pack can limit their foraging and movement, high elevation and increasing temperatures can make their habitat less suitable.

Answer:

Decrease in predators and high nutrition
