Consider a forest ecosystem where increased temperatures lead to more frequent wildfires. These fires reduce the forest cover, which in turn increases the amount of sunlight reaching the ground, leading to further drying and increased fire risk. What type of feedback loop is this?

Positive feedback loop, amplifying the initial change. (C) Signup and view all the answers

Imagine a lake ecosystem where increased nutrient runoff leads to excessive algae growth. This, in turn, reduces sunlight penetration, killing aquatic plants and decreasing oxygen levels, ultimately leading to fish die-offs. Initially, this might cause a decrease in algae as their food source diminishes, but the lack of oxygen continues the cycle. What concept is exemplified by this situation?
