OUR BLUE PLANET BIO BEYOND FINAL EXAM ACTUAL
QUESTIONS AND SOLUTIONS RATED A+
✔✔Caribou are migratory animals. In what biome do they spend their winters? In what
biome do they spend the spring? Why must they migrate? (This isn't offered directly by
the documentary - think about where they can optimize their chances of survival.) How
far is this migration? - ✔✔forest(frozen lake)
tundra
they must migrate to escape predators, food, mate, shelter, weather protection
hundreds of miles(600 km)
✔✔What has happened to the population of caribou in the last 20 years? - ✔✔lost 70%
✔✔True or false: The polar regions are warming faster than any other part of the planet.
- ✔✔T
✔✔What impact is this having on polar bears? - ✔✔sea ice is disappearing
hunting season is getting shorter
cubs are underweight, reduces survival chance
✔✔In what way does the glacial ice of Greenland, along with sea ice, protect our
planet? - ✔✔by reflecting solar radiation away from the surface
preventing earth overheating
✔✔What is the impact of the increase in glacier melt? (Hint - three effects are
mentioned.) - ✔✔creates a colossal tidal wave
75 million tons of ice break free
feeding fresh water into sea
coast of peru would fall silent
raising sea levels, changing salinity, disrupting ocean currents
✔✔Our Planet - Jungles Viewing Guide - ✔✔plz complete uwu
✔✔True or False: the rainforest is the richest habitat on earth. - ✔✔true
✔✔Tropical forests cover ___ percent of the land area on earth - ✔✔7%
✔✔Where is the planet's "youngest" tropical rainforest? About how old is it? What else
is unusual about this tropical rainforest - ✔✔In the heart of Africa lies the Congo ->
18,000 years old
✔✔What is the effect of poaching on the silverback gorillas? - ✔✔in the last 20 years,
poaching for bushmeat has halved the Congo's gorilla population - critically endangered
, ✔✔Why does Attenborough say that many trees in the jungle you identified #3 owe their
survival to silverback gorillas and forest elephants? - ✔✔Both gorillas and forest
elephants are seed dispersers
✔✔What is a "bais"? What important resources do gorillas and forest elephants find in
the "bais"? (If you google Mbeli Bai, you'll also see a short description, but the
documentary mentions one critical resource that Google does not). - ✔✔open areas/
clearings that attract many of the jungle's inhabitants. Water areas with growing
vegetation. Animals feed on aquatic plants rich in salt (a mineral in short supply inside
the forest and crucial to their survival) and drink the mineral-enriched water. The bais is
where elephants and others to meet other animals. A refuge from poaching.
✔✔What is special about the plants and animals found on New Guinea? - ✔✔the
world's largest jungle-covered island and the plants/animals found on it can be found
nowhere else on Earth
✔✔Speaking of bizarre creatures: what does the twelve-wired bird-of-paradise do with
its tail? How does the male Western Parotia attract a female? - ✔✔They use their tails
to tickle the face of a prospective mate. Builds a tidy court for the mate. He dances for
his mate. Bows, eyes turns yellow, dances and spin (his wings fan out looking like a tutu
this is so silly and cute). Flashes his iridescent throat patch
✔✔Where is the oldest rainforest on Earth and how long has it grown there? - ✔✔The
jungles of Borneo in Southeast Asia have grown for nearly 130 million years
✔✔How does a velvet worm detect its prey? - ✔✔one of the oldest predators on Earth.
It detects its insect prey through vibration and touch. Catches pray with glue guns and
immobilizes the prey
✔✔How are pitcher plants well adapted to get the nutrients they need? - ✔✔They rely
on other animals like the mountain treeshew. The treeshew eats the sugary solution
found on the hairs of the pitchers lid. The threeshews feces are fertilizer for the plant.
Ants who feed off the sugary of the pitcher can get knocked in the pitcher's mouth by
rainfall. Wolly bats roost in the pitcher plants (because the plants board back wall
reflects the bat's ultrasound) and night and also drops feces for the plant.
✔✔What has happened to Borneo over the last 50 years? What about in the
Philippines? - ✔✔lost over half of its jungle. In the Philippines, 90% of the primary
rainforest has been lost
✔✔What is world's rarest bird of prey? - ✔✔Philippines eagle
✔✔How big is the Amazon basin? - ✔✔over 3,000 kilometers across
