4 Adaptation Flashcards
What do plants need to survive? (5)
Water Nutrients Carbon dioxide Light Space
What do animals need to survive? (3)
Food (from other organisms)
Water
Oxygen
Define ‘Adaptation’.
An adaptation allows organisms to survive in a particular habitat, even when the conditions are extreme.
Define ‘Extremophile’.
An organism which lives in environments, which are very extreme.
What temperature do most organism live in and why?
Below 40 degrees Celsius.
So that their enzymes can work.
Explain what adaptations animals in cold climates have.
Thick fur
Blubber under the skin - insulates and keeps them warm.
How do animals in the desert adapt to their conditions?
To conserve water
Stop themselves from getting too hot.
May hunt/feed at night so that they remain cool in the day. This also means their prey are less likely to see them hunting at night.
How may plants lose water?
Water vapour can escape through stomata. (Holes in the leaves)
What are the ways plants adapt to collect and conserve water?
Extensive root system - collect water from far down in the soil where other plants can’t reach.
Small or waxy leaves.
Swollen stem- to store water.
How have plants adapted to put off being eaten by animals? (3)
Thorns.
Poisonous chemicals.
Warning colours.
What animals in competition for? (5)
Water Food Space Mates Breeding sites
What must an animals territory be large enough for?
To find….
Water
Food
Space for breeding
What do plants compete for? (3) and give an example of this adaptation.
Water
Nutrients
Light
In a woodland, smaller plants flower before trees to that they get enough water, nutrients and light before the trees block the light and use other nutrients.
Why do plants try to spread their seeds as far as possible?
So that they don’t compete with themselves.
What non-living factors may cause the conditions of an environment to change? (4)
Temperature
Light
Rainfall
Oxygen levels
