FINAL 2019: Ecosystems out of Balance

Define euthrophication

• A natural process of change over time in a lake or pond where nutrients build up causing an increase in a growth of algae

• human activity such as spreading fertilizer or poorly septic tanks an

• a form reproduction of yeasts in which a new yeast cell grows out of the body of the parent

How does climate change lead to an increase in algal blooms?

• Decreased temperatures lead to an increase in phytoplankton growth.

• Increased levels of carbon dioxide, a greenhouse gas, leads to increased phytoplankton growth.

• Increased pollution leads to lower levels of nutrients in aquatic ecosystems and therefore an increase in phytoplankton growth.

• Decreased water levels caused by climate change lead to an increase in phytoplankton growth.
