Role Call
These organisms get their energy directly from the sun.
What are Producers/Plants?
In a food chain diagram, the arrow always points to this.
What is the eater / the animal receiving the energy?
This disaster is a long period of time with little or no rain.
What is a Drought?
On a bar graph, the tallest bar usually represents this vocabulary word meaning "too much".
What is Overabundance?
Cutting down a forest to build a mall is an example of this type of impact.
What is Negative / Harmful?
This type of organism must eat other plants or animals to get energy.
What is a Consumer?
This model shows many overlapping food chains in an ecosystem.
What is a Food Web?
During a drought, this organism dies first because it needs moist soil to survive.
What is the Earthworm?
If the Rabbit population becomes Overabundant, the Grass population becomes this.
What is Scarce / Scarcity?
Planting new trees to replace old ones (Reforestation) is an example of this type of impact.
What is Positive / Helpful?
These "cleanup crew" organisms break down dead matter and return nutrients to the soil.
What are Decomposers/Fungi/Bacteria?
Identify the Apex Predator in this chain: Sun -> Grass -> Zebra -> Lion.
What is the Lion?
Hurricanes destroy sand dunes and forests, but they do NOT do this to sea life.
What is increase/help it?
In the data table, if the prey population drops from 100 to 20, the predator population will likely do this.
What is Decrease?
Pollution from parking lots often washes into streams and kills these organisms first.
What are insects/fish?
True or False: Decomposers give energy to the sun.
What is False? They give nutrients to the soil.
This "arch-stone" species holds the entire ecosystem together; without it, the web crashes.
What is a Keystone Species?
If a fire burns all the grass, this happens to the mice.
What is they decrease/starve?
True or False: Changes to one population rarely affect other populations.
What is False?
To help squirrels, a builder might leave these standing in a new neighborhood.
What are Trees / Habitats?
A bear eats berries and fish. This makes the bear this specific type of consumer.
What is an Omnivore/Secondary Consumer?
In the Pacific Ocean, this Keystone Species eats sea urchins to protect the kelp forests.
What is the Sea Otter?
Storm surges from hurricanes push this type of water into freshwater lakes, killing the fish.
What is Saltwater?
If a graph shows a deer population jumping from 10 to 150 in one year, it is likely that this happened to their predators.
What is they were removed / decreased?
This term means "protecting" nature, like creating a park where no one can build.
What is Conservation?
