Habitats and Niches
What is a habitat? + give an example
an area with a particular combination environmental factors that affect which organisms can live within it
Ex. Cape May Warbler Birds live in northern spruce trees
What are the three symbioses?
Commensalism
Mutualism
Parasitism
What is tolerance + an example
Tolerance is the range of external conditions within which a species can survive and reproduce
Ex. Saltwater fish can tolerate salty water, but living in freshwater may cause them to die because they can't tolerate it
What is a pioneer species?
What are the three types of biodiversity?
Ecosystem diversity
Species diversity
Genetic diversity
What is a niche? + give an example
includes the range of physical and biological conditions in which it can survive and reproduce, as well as the way it obtains the resources it needs
habitat+role in the habitat
Ex. Cape May Warbler Birds live in northern spruce trees and feeds at the tips of branches near the top of the tree
Which symbiosis is represented by
+,-
parasitism
What is the competitive exclusion theory?
No two species can occupy exactly the same niche in exactly the same habitat at exactly the same time
This is the example of primary or secondary succession? and how do you know?
Barren rock--> Lichen grows-->trees and plants growing--> full ecosystem
Primary succession
What kind of biodiversity is this an example of
"a variety of different small fish species, species of coral, and species of clams all live in a coral reef in the pacific ocean."
What is the difference between a habitat and a niche?
Habitat is where is lives
Niche is where it lives and its role in that environment
Which symbiosis is represented by
(+,0)
commensalism
What is it called when organisms of the same species compete for resources
Intraspecific competition
What does barren mean? AND do we use it when describing the events of primary or secondary succession?
Empty/nothing is growing
First step of primary succession
What is ecosystem resilience?
Ecosystem resilience describes a system’s ability to recover after a disturbance
What is "Cape May Warbler Birds live in northern spruce trees and feeds at the tips of branches near the top of the tree" an example of
a Niche because it includes the role
A clownfish lives in an anemone. The clownfish is protected by the stinging tentacles of the anemone. The clownfish scares off predators from eating the anemone with its bright orange and white colors. This is an example of which symbioses
Both are benefited (+,+)
Can two species maintain the same niche? Why or why not?
No two species cannot share the same niche according to the competitive exclusion theory.
They will either divide resources or one will thrive and one will die
What word do we use to describe the ecosystem at the "end" of the succession?
Climax community
A prairedog lives in ecosystem full of many different species of plants and grass.
His ecosystem is very diverse, what does this mean for the resilience of his ecosystem?
The more diverse an ecosystem is the more resilient it is to change/damage
What is Rachels niche?
Deep down in the pacific ocean, a clownfish named Rachel, lives near a coral reed in an anemone. The coral reef is home to many fish and algae. When Rachel is hungry she swims over to the reef and eats some of the algae living on the coral reef.
Rachel lives deep down in the pacific ocean in an anemone. Rachel the clownfish swims and eats the algae in a near by coral reef.
anything that is +,0
A barnacle and a whale
According to the competitive exclusion theory what will happen in the following scenario?
Two species of roaches are placed into the same environment and are competing for the same food source for a long while...
Divide resources or one population will thrive and the other will die
Tell me the order of secondary succession
Ecosystem thriving--> natural disaster--> little plants left/starting to grow--> ecosystem thriving
What is Ms. Zimmermans dogs name?
Ziggy :)
