Biodiversity
What does biodiversity refer to?
1) The variety of living organisms,
2) The genetic differences among organisms
3) The communities and ecosystems in which organisms occur.
What is symbiosis?
ANY relationship in which two species live closely together!
What is competition?
The struggle between organisms to survive as they used the same limited resources.
What is an adaptation?
A characteristic within an ecosystem that helps it survive within its environment.
What is primary succession?
Disruptions to the physical or biological components of an ecosystem can impact organism populations living there.
How many species have scientists identified?
1.9 Million
What is mutualism?
When both organisms benefit.
What is predation?
An interaction where one organism kills another for food or nutrients.
What is a niche? Name the three parts that a niche can include.
Includes how an organism obtains its food, the type of food the organism eats, and what other organisms eat it.
What is secondary succession?
The series of changes that occur in an area where the ecosystem has been disturbed, but where soil and organisms already exist.
What is genetic diversity? Please give an example as well.
Inherited traits in the genetic makeup of an entire species (example: blue eyes or brown hair)
What is parasitism?
When one organism benefits and the other is harmed.
BONUS:
What did we use to represent our limited resources in class for the competition and predation lab?
Beads
Give an example of an adaptation!
Giraffes have a long neck to be able to reach the high trees
Which type of succession (primary or secondary) has changes occur in an area where NO SOIL is present?
Primary Succession
What is species diversity? Please give an example as well.
The variety of life within a specific area or the number of different species and their abundance (example: how many lions within a desert).
What is commensalism?
Where one organism benefits and the other is unaffected/neutral.
What are limited resources? Please give an example as well.
Things needed to survive in life (example: food, water, or shelter)
*These are not available in endless supply and can run out if used too quickly.
Give an example of a niche!
A camel lives in the desert, eats grasses and leaves, and can get eaten by mountain lions.
How long does primary succession AND secondary succession take?
Primary: 1000 years
Secondary: 100 years
What is ecosystem diversity? Please give an example as well.
The different types of ecosystems and their interactions (example: deserts, forests, grasslands, wetlands, or oceans).
Give an example of EACH type of symbiotic relationship.
3. Commensalism: Bird and Nest
Give an example of predation AND competition
Competition: Two flowers competing for sunlight
Predation: A frog eating a fly
What is a KEYSTONE species? Please given an example as well.
A species that influences the survival of many other species in an ecosystem. A keystone species holds the ecosystem together. Example: Bees, Wolves at Yellowstone National Park, or Beavers.
What is a PIONEER species?
These are the first species to populate an area
