These are smaller areas within a larger habitat
Microhabitat
Bacteria that live in the soil, water, and our gut
Microbiome
The environmental conditions in which an organism can survive
Tolerance
An animal's habitat, what it eats, and how it interacts with the environment
Niche

Keystone species
Give 3 examples of a keystone species
Sea otters, Wolves, Orange & Purple Starfish, Elephants
What happened in Yellowstone National Park when the wolves were removed?
The elk population more than doubled which caused many problems in the ecosystem.
OR
The wolves being removed caused a trophic cascade in the ecosystem
In this relationship, one organism benefits while the other is harmed
Parasitism
In this relationship both organisms benefit
Mutualism
In the video about the sea otters, what animal began eating the otters?
Orca/Killer whale
What is an example of commensalism?
Cattle egret and cattle
Relationships where at least one species benefits
Symbiosis
Relationship where one species benefits, but the other is not harmed or bothered
Commensalism
What is an example of mutualism?
Clownfish and Sea anemone
What is meant by the phrase: "Some animals are more equal than others?"

The elk overgrazed all the berries and trees
The elk dirtied the river water
The elk eroded the river banks
What is the graph of the zebra, wildebeest, and gazelle an example of?
Resource/niche partitioning
What is an example of parasitism?
Ticks, fleas, tapeworms, zombie flies, head lice etc
(The teacher can allow for more answers as they see fit)
What role did the wolf play in the food chain?
Apex predator or
Keystone species or
Tertiary consumer or
Top predator
No two organisms can occupy the same niche
Competitive exclusion principle
Organisms occupy different niches in order to reduce competition over resources
Resource partitioning
What was the name of the hypothesis that says "Predators control the herbivores so they don't eat all the plants?"
The Green World Hypothesis
What was the trophic cascade in the tide pools?
The removal of the starfish caused the mussel population to explode which led to a loss in other species
What term best describes the example of the five species of warblers living in the same tree?
