Interdependence and Adaption - B1
- Organisms are well adapted to survive
in their normal environment
- changes in the environment may affect the
distribution and behaviour of organisms
- environments are changing constantly due to
living and non-living factors
- this affects the distribution of organisms living there
- some non-living factors:
- pollution
- floods
- droughts
- temperature changes
- living indicators:
- lichen populations can be used
to determine levels of sulphur
dioxide in the air
- invertebrates living in ponds and streams
indicate water pollution and the
concentration of dissolved oxygen
- lichen populations can be used
to determine levels of sulphur
dioxide in the air
- non-living indicators
measure these changes:
- oxygen levels
- temperature
- rainfall
- oxygen levels
- pollution
- some non-living factors:
- this affects the distribution of organisms living there
- environments are changing constantly due to
living and non-living factors
- changes in the environment may affect the
distribution and behaviour of organisms
- Population size depends on a
variety of factors including:
- COMPETITION
- all animals and plants require
a supply of materials from their
surroundings and from other
organisms that live there
- ANIMALS
- compete for:
- food
- mates
- territory
- food
- compete for:
- PLANTS
- compete for:
- light
- space
- water
- nutrients from soil
- light
- compete for:
- ADAPTATION
- organisms including microorganisms
have features and adaptations that
enable them to get the materials they
need from their habitat and survive
- COLD ENVIRONMENT
- e.g. polar bears
- a thick layer of fat for
energy and insulation
- thick fur for insulation
- white fur for camoflauge
- large canine teeth for killing
- large paws for swimming
- a thick layer of fat for
energy and insulation
- e.g. polar bears
- HOT, DRY ENVIRONMENTS
- e.g. camels
- fat stored in a hump, as a
supply of food and water
- thick fur for insulation for cold
nights and hot days
- large feet for walking on soft sand
- long eyelashes to keep sand out of their eyes
- nostrils that close
during sandstorms
- fat stored in a hump, as a
supply of food and water
- PLANT ADAPTATIONS
- e.g. cacti
- large root systems
- small surface area of leaves
to reduce water loss
- waxy surface of leaves
- water storage tissue
- large root systems
- e.g. cacti
- e.g. camels
- organisms including microorganisms
have features and adaptations that
enable them to get the materials they
need from their habitat and survive
- ANIMALS
- all animals and plants require
a supply of materials from their
surroundings and from other
organisms that live there
- PREDATION
- DISEASE
- HUMAN INFLUENCES
- COMPETITION
