What is the sun?
200
Don't let their massive size fool you! Horses are this kind of consumer, primarily eating grass and hay.
What is an herbivore?
200
Fish are able to breathe because their gills can take in this gas from the water around them.
What is oxygen?
200
Plants wouldn't be able to survive without decomposers. They perform this key role in the ecosystem that helps plants get what they need.
What is recycle nutrients/put nutrients into the environment?
200
Animals get this by taking in food. Plants get this by taking in sunlight.
What is energy?
300

Water that runs along a surface, often carrying waste or nutrients with it.
What is runoff?
300
Plants release this: the gas that all living animals (including you) need to breathe.
What is oxygen?
300
The arrows in a food chain show the transfer of this.
What is energy/matter?
400
Phytoplankton might be tiny, but they're still ______________, since they use sunlight and carbon dioxide to make their own food.
What is a plant/producer?
400
Harmful algae blooms are caused by too much of this.
What are excess nutrients in the water?/What are heat, waste, and fertilizer?
400
Plants are able to grow (mostly) because of the nutrients they get from this.
What is carbon dioxide?
400
A predator at the top of the food chain and has no predators itself is called this.
What is an apex predator?

What are stomata?

What is the mouse population will increase?
What is the deer population will increase?
