Learning objectives
We are learning to: appreciate how some organisms live in very
unusual conditions.
What I’m looking for:
- You recognise what an extremophile
is
- You learn about three case studies
and can explain how they are adapted
to their environment.
- You can explain factors that affect
the distribution of organisms
- You learn about changes taking place
in Britain in terms of its birds and
bees!!

What do you think an
extremophile is?

Extremophiles
Extremophiles are organisms that live in very
extreme environments and can survive
conditions that would kill most other organisms.
The extreme conditions can include:
High temperatures
High concentrations of salt in water
High pressures.
Certain bacteria can live in hot springs or around deep-sea hydrothermal
vents, where the water can be very hot. Certain plants grow well in salt
marshes where the salt concentration is too high for most plants.

1. How do they survive? Figs and
fig wasps
There are
about 700
different
species
(varieties) of
fig trees.
For one of
these babies
(the female)
so that he
can fertile
her
Inside the
fig fruit
lives a male
fig wasp....
It’s
waiting......
He has lots of
adaptations like
losing his wings and
he has small eyes so
he can wiggle
around to find the
love of his life.
2. How do they survive? Starnosed mole
Do you know how
long it takes us to
react to a crisis?
With one fast move,
gulp, gulp, it’s gone...
650 milliseconds!
Why do you think it
has to be so fast?
Do you know how
long it takes this
mole to react?
Because it is
nearly blind!
The star-nosed mole lives in wet low
places
230 milliseconds!!
That’s even faster!!
How do you think it’s
nose is adapted to
catching its prey?
That’s right, it uses this sense organ to detect smell
and touch...did you know it is nearly blind?
3. How do they survive? The Venus
fly trap
Venus fly traps live in bogs. These are wet soils that don’t have a lot of
nutrients. Can you explain how it is adapted so it can get nutrients?
The Venus fly trap has a red
colour inside and contains sweet
smelling nectar. When an insect
touches its hair, just like a reflex,
it acts quick and traps it... And it
eats it up and uses the insects to
get its nutrients...yum

You can explain factors that
affect the distribution of
organisms
• Lots of things affect the distribution of
organisms. E.g. Temperature- could you
have a polar bear in a desert?
• Blood worms can survive in low oxygen
water.
• Salmon only survive if there is lots of
oxygen.
You can explain factors that
affect the distribution of
organisms
• When the
environment changes,
so can the organisms
living there. They may
no longer be adapted
to live there.

you see?
industrial
revolution
The white and black bodied peppered
moth
Indicator species
• Living organisms that indicate how much
pollution there is.
Lichens grow in lots of
places...roof’s, trees
etc...there are lots of
different types
An indicator that there may be lots
of pollution is that there will be
fewer types of lichens. The pollution
could be due to more sulphur dioxide
in the air...where does that come
from?
Indicator species
• How can you tell if there’s pollution in
here using your knowledge of indicator
species?
The cleaner the water, the more types of species
there is likely to be

Changing Britain
Ok...great for us...we can put
getting hot hot hot.......!!!
theit’sfan
on...
But what about the birds and
the bees?
What does the red line tell you about
the average temperature of Britain
each summer?
The Dartford warbler
We used to have lots. But
after cold winters, many
didn’t survive 
There’s lots in South Europe
where it is hot.....
As it gets hotter, they are
surviving (the few we have
left) and reproducing and
making more!!! Woooo!!
In Spain, the numbers are
getting lower due to it getting
hotter.
What do you think will
happen here after a few
decades?
Think of a world without any bees..
Bees pollinate plants as they collect the nectar to make honey....no bees,
no honey...so honey prices go????
Why?????
Also, without bees as pollinators, we would have no strawberries, apples,
raspberries etc 
We don’t know....
• It could be climate
• It could be CCD- colony collapse
disorder- a mystery disease where they
are just dying.
• What are scientists doing?
- They are breeding disease resistant
strains. How may this help?
