Warm up # 28 ( Unit 2 Article Due Tomorrow)
1) What do you know about the following terms:
a) Evolutionb) Communityc) Extinctiond) Genes2) Describe what you see in video on “Maple
Copters”
Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct.
In nature there are 2 keys to survival: gaining energy and reproducing.
Warm Up # 221) What makes you unique?
2) What does the word “evolution” mean?
3) Why do you think species would change over time?
Warm Up 291) You and a friend are chased by a grizzly bear. List some
possible ways you can survive. (not harming the bear)2) A school of fish are chased by a shark, which fish gets
eaten?
3) Which of the fish are most likely to reach adulthood and reproduce?
4) What does the word “evolution” mean?
Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct.
In nature there are 2 keys to survival: gaining energy and reproducing.
2) A reintroduced population of wolves in a national park is 90% grey and 10% black, consistent with the wolf population in other regions. After several generations in isolation, the national park’s wolf population is 60% grey and 40% black. The wolf population has likely experiencedA. natural selection.B. genetic drift.C. mutations.D. migration.
Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct.
In nature there are 2 keys to survival: gaining energy and
reproducing. Need to fit your habitat!5) Explain how/why a desert fox might look
different than one in Audubon.
Warm Up 31: Matching…8 questions
1) Humans breed dogs a) natural selection2) Genetic characteristics of b) evolution population change c) artificial selection3) Bacteria are not killed by d) adaptationhand sanitizer e) resistance4) Camouflage of insect keepsit safe5) More camouflage insectssurvive and reproduce
8) One of the conditions for natural selection is “Individuals vary in fitness, or reproductive success” Explain what that means.
2) One of the conditions for natural selection is “Individuals vary in fitness, or reproductive success” Explain what that means.
Warm Up 341) Which “beak” was best for:a) Penniesb) Sandc) Water
2) How is this lab a demonstration of survival of the fittest (natural selection)?
3) What happens to a species if it is unable to adapt to changes in its environment?
Warm Up 351) Copy the chart below. For the species indicate
either positive (+), negative (-) interaction, or no impact (o).
INTERACTION Species A Species B
Commensalism
Herbivory
Mutualism
Parasitism
Predation
2) Explain how mutualism and commensalism are different from each other.
3) How are parasitism, herbivory and predation similar?
Warm Up 36 (3 Questions)
1) Define the following terms and give example
a)Producerb)Consumerc)Herbivored)Carnivoree)Omnivoref)Decomposer
2) Use an example to explain how you are solar powered.
3) Explain why photosynthesis is so important to life on Earth.
2) In the food web below, give an example of:a)Producer b) Primary Consumer c)
Secondary Consumer
3) If there were 100 units of energy in the grass, by eating the grass how many unit of energy would the mouse have?
4) In an ecosystem why are there so few owls compared to grass?
5) How do herbivores have an advantage on carnivores?
6) Describe what some possible effects are if there is a disease killing off mice.
7) Which population would you expect to be: a) smallest, b) largest?
Yesterday You Learned… 1) There is a huge diversity of life on Earth that
is critical to all species.2) We call that variety of life BIODIVERSITY.3) There are 3 types: ecosystem, genetic and
species diversity.4) Biodiversity is important for: food webs to
function, medical reasons, ethical reasons and more
VIDEO: HOW WE DISCOVER NEW SPECIES
Warm Up 351) Why do you think some species go extinct?2) What do you know about “mass
extinctions?”3) Do you think we should worry about other
species going extinct? WHY?
