Answer:
Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.
Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
Explanation:
The evaporation of water from the leaf is called transpiration. The number of stomata on leaf surfaces varies widely among different species of plants. ... Researchers have evidence which indicates that stomata densities change in response to changing atmospheric levels of carbon dioxide.
The thick loess deposits in South Dakota, Nebraska, and Iowa come from the glacial sediments from the last ice age glacial period.
