Adapt to Fit B2e
OBJECTIVES Grade G-E • Recognise that plants & animals are adapted to their habitats • Describe how some animals are adapted to be successful predators • Describe how some animals are adapted to avoid being caught as prey • Recognise why animals and plants that are adapted to their habitats Grade D-C • Explain how a polar bear & camel are adapted to the conditions they live in • Explain how animals and plants that are adapted to an environment are better able to compete for limited resources. Grade B-A* • Explain how a cactus is adapted to hot dry conditions • Explain how plants are adapted for wind or insect pollination • Explain how the adaptations of animals and plants determine their distribution and abundance.
Animal adaptations Task: Use pages72-3 to make notes on the adaptations of the camel and cactus. Camel Cactus Lay your work out as 2 big ideas. (10 minutes)
Task • Research the brown bear and the polar bear. • Compare and contrast their habitats and adaptations to the challenges they face. • Complete the worksheet B2e2.
colourful, scented petals attract insects nectar, a source of food for insects, is deep within the flower large, sticky pollen grains become attached to the insect’s body stiff anthers and stigmas are positioned where insects must brush past them Adaptations for insect pollination How are flowers adapted for pollination by insects such as bees and butterflies?
huge numbers of light, tiny pollen grains small, dull-coloured petals anthers hang loosely outside flower so wind can blow pollen long, feathery stigma hanging outside flower so pollen can be trapped Adaptations for wind pollination How are flowers adapted for pollination by the wind?
Unusual plant adaptations Plants can livein acid or waterlogged soils where there is little nitrate. Some plants have evolved a rather cunning adaptation to obtain the nutrients they need. Pitcher plants have a large hollow filled with fluid that traps insects or other small organisms that may fall in. Hairs on the slippery inside of the plant are angled down to ensure that the victim cannot escape! The plant digests its victims to absorb the nitrates it needs!
