- Adaptation to survive
- Adapt and Survive
- Organisms need materials arround them to survive
- Plants:
- Need light, CO'2 , water, oxygen and neutrients from the soil
- Animals:
- Need food from other organisms , water and oxygen
- Adaptations:
- Special features of an organism
- Herbivores: Eat plants
- Carnivores: eat other animals
- Most organisms live in temperatures below 40C
- emzymes can work
- Extremophiles
- Microorganisms adapt to living in coditions where emzymes wont usually work because they would dementure
- Adaptation in aminals
- If animals are not adapted , they would die
- Cold Climates : Eg Artic
- Thick fur and blubber (fat) under the skin to keep warm
- Artic Fox:
- White fur in winter and brown fur in summer
- Camouflage
- White fur in winter and brown fur in summer
- Competition in Animals
- Animals are in competition with each other for food, water, space, mates and breeding sites
- Preditors: hunters
- Preys: hunters victom
- Adaptation in Plants
- plants lose water vapour from the leaf surface
- Plants reduce the surface area of leaves to survive dry conditions
- Measuring Enviromental Change
- Change can affect the distribution of living organisms
- Non-living Factors
- Temperature, rainfall, light and oxygen levels
- Living Factors
- Arrival of a new predetor or desease, introduction of new plants.
- Indicator species- Indicate changes in the enviroment
- The Impact of Changes
- Changes can affect the distribution of living organisms.
- Data on the effects of environmental change is not always easy to interpret.
