Ecology Basics
What is ecology?
The study of the relationships between organisms and the living and nonliving parts of the environment.
What are adaptations?
Characteristics that make an organism better suited to its environment.
Roll the dice: points x the number
Who is considered the father of evolution?
Charles Darwin
What does the term “carrying capacity” mean?
Bonus 200pts: draw a graph of what it looks like
The maximum population size an ecosystem can support.
Roll the dice: points x the number
Which members of BTS are currently in the military?
RM, Suga, V, JK, Jimin
What term describes the physical environment where an organism can survive?
Habitat.
Give an example of a structural adaptation of a mammal in the arctic.
The thick fur of a polar bear, which helps it survive cold temperatures.

Describe natural selection in one sentence.
Natural selection is the process where organisms with favorable traits are more likely to survive and reproduce, passing on those traits.
Coin flip! Double or nothing.
Define mutualism and give an example.
Mutualism is a symbiotic relationship where both species benefit, such as clownfish and sea anemones.
What is the name of Jin's new album coming out in 10 days?
Happy!
What is the term for non-living factors like climate and soil in an ecosystem?
Abiotic factors.
Bonus 100 points: give 3 examples.
What term describes the ideal conditions for an organism’s survival?
Optimal range

What is genetic drift, and in what size of populations does it most often occur?
Genetic drift is a change in gene frequency due to random chance, often occurring in small populations.
Coin flip! Double or nothing.
What is a Type I survivorship curve, and what organisms typically follow it?
Type I survivorship shows low mortality in early life with high mortality in old age, typical for humans.
Bonus 100pts: Draw the Type I survivorship curve.
With ________ songs attributed to his name as a songwriter and composer by the Korea Music Copyright Association (KOMCA) as of September 2024, RM is the youngest most-credited songwriter in Korea.
+/- 20

What is a population in ecological terms? Give an example while thinking about a jungle biome.
All members of a species that live in the same area at the same time.

Explain the concepts of zones of physiological stress and zones of intolerance.
Zones of physiological stress are where conditions are less than ideal, leading to stress in organisms, while zones of intolerance are where conditions are so extreme that organisms cannot survive.

Explain the founder effect and provide an example.
The founder effect occurs when a few individuals migrate to a new area, establishing a population with a limited gene pool, such as a species colonizing an island.
Differentiate between r-selected and K-selected species. Give an example of each and justify why.
r-selected species have many offspring and low parental care, while K-selected species have fewer offspring with high parental care.

Name 5 out of the 7 BT21 characters created by BTS.
Cookie, Shooky, Chimmy, Koya, RJ, Mang, Tata
Bonus 100 pts: who is the character that represents ARMY?
Explain the difference between a community and an ecosystem.
A community includes all populations in an area, while an ecosystem includes the community plus the physical environment.
How might climate change challenge the adaptations of Arctic species like polar bears, and what limits could prevent them from evolving quickly enough?
Climate change threatens polar bears' tolerance range, impacting their ability to hunt and breed on melting sea ice. Their physiological (fat storage) and structural adaptations (wide paws for ice) are poorly suited for warmer conditions, and behavioral shifts, like traveling farther, may not suffice. Rapid climate change outpaces slow evolutionary responses, limiting their survival.
Explain how the bottleneck effect can reduce genetic diversity in a population, and why this can be a disadvantage in a changing environment.
The bottleneck effect occurs when a population sharply declines, reducing genetic variety. With fewer genes, there's less adaptive potential, making the population more vulnerable to environmental changes or diseases.
How does carrying capacity influence population growth, and what are some factors that can cause a population to exceed it temporarily?
Carrying capacity is the maximum number an ecosystem can sustain. Populations may overshoot due to abundant resources but face diebacks when resources run out, triggered by competition, waste, or disease
Who will be the last BTS member to exit the military?
Suga...by 1 day
