A wolf population is introduced into an ecosystem, causing the deer population to decrease. The wolf population decreases as the deer population decreases, allowing the deer to begin to increase again. This is an example of what type of feedback?

• Neutral

• Ecosystem

• Positive

• Negative

Polar Ice Caps are melting due to an increase in Earth's temperature. This lowers the albedo of Earth, which in turn increases Earth's temperature. This is an example of what type of feedback?

• Negative

• Neutral

• Positive

• Ecosystem
