How are these organisms adapted to their environment?
Extra challenge:
Thermophile bacteriaSlide4
What do we mean by competition?Slide5
Why do animals and plants compete?
Competition:
Animals and plants have to compete for limited resources. The best adapted animals or plants will win and survive. Slide6
Task 1:
What might animals compete for?Slide7
Animals mainly compete for:
Food
Territory
A mate
Plants mainly compete for:
Water/minerals from the soil
Sunlight
Plants and animals compete with each other for the things they need.
The organism that is better adapted will win the competition and survive.
The organism that loses will either die or move to another habitat.Slide8

Resource
How are the predators and prey competing?
What adaptations do they have to help them?FoodWolf-to get food
Caribou-competing not to get eatenRun fast, good sense of smell,
sharp teeth, good sight and hearing,Long legs to run fast, eyes on side of head to see predatorsSlide11
Clip 2: Attracting mates
Sings. Males with the most complicated songs will attract more females
Builds a bower and collects brightly coloured objects to decorate it. Females mate with males that have the most decorated bower.Slide12
Task 2:
What might plants compete for?Slide13
Plants shed seeds far away so the parent plant is not in competition with its offspring
To keep tissues rigid and supported and for photosynthesis
So plants can make all the chemicals they need in their cells
For photosynthesis. Making food using the energy from the sunWhat do plants compete for?WaterLightMinerals & nutrients from the soil
SpaceLO: Explain what plants and animals compete for.Slide14

What is different about competition in plants and animals?
LO: Compare competition in plants and animals.Slide16
What are the animals competing for in each picture?
What happens if they lose?
Move area, Adopt new strategies, Extinct/dieSlide17
AdaptationSlide18Slide19Slide20
ALOE VERA Slide21
ALOE VERA
Can store large amounts of water in leaves and stems enough to last between rain showers
Has a shallow but very large network of roots letting it absorb lots of water when it rains.
No true leaves, which would lose water rapidly.Slide22
Arctic hare.Slide23
Arctic hare.
Small eyes and ears for protection against the cold. Small ears keep heat loss low.
Insulating fat layer and thick fur reduce heat loss.
White fur in winter for camouflage. Becomes grey in summer. Slide24
Desert hareSlide25
Desert hare
Thin fur coat that allows heat loss.
Large ears that radiate heat out.
- Very little insulating body fat. Slide26
OspreySlide27
Osprey
Sharp talons for catching prey and holding it.
Muscular legs for lifting prey.
Forward facing eyes giving binocular vision. Allows excellent distance judgementSlide28
BaracudaSlide29
streamlined shape
to reduce friction when moving through water
gills have a
large surface area
so that oxygen can be
extracted from the surrounding water
fins
provide stability, power and control
Sharp teeth and strong jaws for catching and eating prey.Slide30
Drosera (Sun dew plant). Nicknamed the sticky fly trap plant.Slide31
Drosera
(Sun dew plant). Nicknamed the sticky fly trap plant.
Produces a sugary substance that attracts insects.
Insect movement triggers sticky hairs hold the insect.
Plant makes enzymes that digest the insect.
Lives in low nutrient soils so gets nutrients from insects.Slide32
Flounder fishSlide33
Flounder fish
Camouflaged against the sea bed.
Upward facing eyes to look for predators and food.
Muscular body and large back fin allows burrowing into sand and fast movement along sea bed.Slide34
LionSlide35
-Camouflaged against dry grass allowing prey to be stalked
.
-Forward facing eyes allow good distance judgement.
- Sharp retractable claws for holding prey.
LionSlide36
Desert gazelleSlide37
Desert gazelle
Highly efficient kidneys that waste little water.
Long thin legs allow heat loss from the underside of the animal.
Thin fur and large ears allow rapid heat loss.Slide38
Compare these two hares and suggest reasons for one of their differences. (A grade)Slide39

Adaptation
(D)
How does that adaptation help it survive? (C)
Predict its habitat or lifestyle and connect this to its adaptation ( B )
Many rows of
sharp teeth
It can capture prey and tear flesh.
It is a top predator capable eating many other animals.
Streamlined shapepowerful fins
It can swim fast to chase and catch prey
It is a top underwater predator capable of chasing, catching and eating many other animals.Slide41
Adaptation
(D)
How does that adaptation help it survive? (C)
Predict its habitat or lifestyle and connect
this to its adaptation ( B )
Hump contains a large fat storeIt can go without food for a long time.
It has
to live for long periods without food such as in deserts where plant life is limited.Highly efficient kidneys
Limits loss of water in urine. It has to live for long times without water such as in deserts where water is scarce.Slide42
Adaptation
(D)
How does that adaptation help it survive? (C)
Predict its habitat or lifestyle and connect this to its adaptation ( B )
Large water store in stem.Meaning it can go a long time without taking in water.
It has to live for long periods without water such as in deserts where rainfall is limited.Very large root system close to surface.
Soaks up lots of water when it has rained.It can get all of its water from a few rain showers per year such as in the desert.Slide43
Adaptation
(D)
How does that adaptation help it survive? (C)
Predict its habitat or lifestyle and connect this to its adaptation ( B )
Trapping mechanismCan catch fliesIt needs to catch and digest fly's because it needs extra nutrients not found in the soil. It lives in poor soils such as bogs.
Bright colour/scentSecretes digestive enzymes
Attracts flies to it.Can digest fliesAs above.Slide44
Predict
how these creatures are adapted for survival and
predict
their habitat.Slide45
Using the knowledge you have gained in the lesson, compare these two foxes giving likely reasons for two of their differences. (A grade question).
