Adaption for survival (B1.4) Flashcards
Adapt and Survive.
All organisms need a supply of materials to survive and reproduce. They get these from their surroundings and from other living organisms.
Organisms are adapted to survive in conditions which the normally live.
Microorganisms have a wide range of adaptations which enable some of them to live in extreme conditions.
Extremophiles.
are microorganisms which are adapted to live in conditions where enzymes won’t usually work because they denature
Adaptation in animals.
Not just what an animal looks like but the animals behaviour swell.
coat colours may change in different seasons.
hot areas = have a large, surface area: volume ratio.
cold areas = small, surface area:volume ratio.
Adaptation in plants.
Plants lose water vapour from the leaf surface.
to survive in dry conditions plants have to adapt to reduce the surface area of leaves, and have tissues which store water and extensive root systems
Competition in animals.
Animals often compete with each other for food, mates and territory.
Well adapted animals are good competitors.
Animals territory will be large enough to find water, food and have space for breeding.
Competition in plants.
Plants compete with each other for light, water and mineral ions from the soil.
Well adapted plants are good competitors.
Some plants use animals to spread their fruits and seeds. Some plants use the wind, or mini explosions.
How do you survive?
Organisms have adaptations which enable them to survive in the conditions which they normally live.
Measuring environmental change.
Change in the environment affect the distribution of living organisms. Changes can be caused by living and non living factors. Environmental changes can be measured using non living indicators. Living organisms can be used as pollution indicators.
