What is a survivorship curve?
Shows number of survivors vs time, shows mortality rate by life stage, aka when a species is most likely to die
What is the smallest unit of ecological organization? A single living thing
Organism
What does the range of tolerance refer to in ecology?
The amount of some abiotic factor that a living thing can survive in
What is an adaptation? Provide an example.
A change in a species that helps its survival
Thumbs, color, camo, sharp teeth
My super cute designer dog, Fozzie, is an example of this human-led type of selection
Artificial selection
Define mutualism and provide an example.
clownfish and anemone, both benefit
What is the difference between r-selected and K-selected species?
K have few offspring but spend time taking care of the offspring
Give the type of survivorship curve and an example
Type 1, Human, Large Mammal, etc
Define a biological community in ecological terms
All of the living things in an area
What letter(s) show the optimal range
C
Sharp teeth of a Jaguar
Physical
Explain the bottleneck effect
the population or gene pool of a species is decreased leading to a smaller amount of traits
What is the difference between parasitism and commensalism?
Commensalism- one benefits, one is unaffected
Provide examples of r-selected species
spider, plant, fish
Give the type of survivorship and an example
type 2, duck, rodents, some turtles, prey at every stage of their life
Explain what an ecosystem encompasses
all of the living and non-living things in an area
What letter(s) show the zone of stress
B and D
Behavioral, Physical, or Physiological:
male Platypi have venemous spurs
physiological
Describe divergent evolution and provide an example.
Similar fore-limb bones in humans, whales, cats. Shows a common ancestor
What relationship do a polar bear and a seal have?
Predator prey
Provide examples of K-selected species
Human, elephant, large mammals
Give the survivorship type and an example
Describe the concept of a biosphere
Where the hydrosphere, lithosphere, and atmosphere meet. Where life can exist.
What letter(s) show the zone of intolerance
A and E
Behavioral, Physical, or Physiological:
Butterflies Migration
Behavioral
Describe convergent evolution and provide an example.
Becoming more similar to fill similar niche. Wings in bats vs wing in butterflies
Does not show common ancestry
What type of competition occurs between a lion and hyena?
Interspecific
What survivorship curve might and r-selected species
type 3
Give an example of a species that may have different survivorship curves based on its ecosystem and explain why.
Turtle, might be type 2 in a pond or type 3 if a sea turtle.
What is the difference between an ecosystem and a habitat?
A habitat is where a single organism or species lives
An ecosystem is all the living and non living things
Explain the implications of climate change on the range of tolerance for certain species
Temperature or climate is an abiotic factor that species have to survive in. A rising temperature may cause some species to die or have to migrate
Discuss how adaptations can lead to evolutionary changes over time.
If it helps a species survive long enough to reproduce the gene will more likely remain in the species gene pool
Explain how coevolution occurs between two species. Give an example
Two species evolve together, pollinator and plant, predator and prey, parasite and prey
What relationships does a mosquito have with a human?
parasitism, predator prey
Why might r-selected species mature faster?
type 3 survivorship, more likely to die when young than adult stage.
