Brain Eating Amoeba
Global Warming
Aquatic Ecosystems
100

These microscopic, plant-like organisms can rapidly multiply in water and sometimes turn it red or green.

What are algae?

100

The scientific name for the so-called "brain eating amoeba"

What is Naegleria fowleri?

100

This gas, related by burning fossil fuels, is the most significant driver of global warming. 

What is carbon dioxide (CO2)?

100

Warmer waters and nutrient pollution together increase the frequency of these toxic events. 

What are harmful algal blooms?

200

This nutrient, often from fertilizer runoff, is the main cause of algal overgrowth in lakes and ocean. 

What is nitrogen?

200

This organism is most commonly found in this type of warm, freshwater environment. 

What are lakes, rivers, or hot springs

200

Global warming leads to the melting of these frozen regions, raising sea levels worldwide.

What are polar ice caps and glaciers?

200

Brain-eating amoebas thrive as climate change warms this type of aquatic environment 

What are freshwater lakes and rivers?

300

When harmful algal blooms occur, they often create these low-oxygen zones that can suffocate marine life. 

What are dead zones?

300

Naegleria fowleri enters the human body through this passageway, not by drinking water. 

What is the nose?

300

As the ocean warms, it absorbs more CO2, causing this chemical process that harms shell-forming organisms/

What is ocean acidification?

300

Rising water temperatures reduce the amount of this essential gas dissolved in aquatic habitats.

What is oxygen?

400

This type of algal bloom produces saxitoxin, which can contaminate shellfish and cause paralytic poisoning.

What is a red tide?

400

Once inside the body, the amoeba travels along this nerve to reach the brain.

What is the olfactory nerve?

400

Warmer ocean temperatures can trigger this phenomenon then causes coral to lose their symbiotic algae.

What is coral bleaching?

400

As aquatic ecosystems warm, species that prefer cold water are forced to do this to survive. 

What is migrate?

500

This process, where excess nutrients cause rapid plant growth and oxygen depletion, is closely tied to HAB formation. 

What is eutrophication?

500

This rare but deadly infections caused by the amoeba has a nearly 97% fatality rate. 

What is primary amebic meningoencephalitis (PAM)?

500

Droughts, crop failures, and changing weather patterns linked to global warming threaten global supplies of this essential resource. 

What is food?

500

Climate driven increases in harmful algal blooms, disease-causing microbes, and habitat loss collectively threaten this concept, referring to the variety of life in ecosystems. 

What is biodiversity?
