Adapt to Fit

B2e

How are they adapted to survive?

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.

Adaptations for insect pollination

How are flowers adapted for pollination by insects such as bees and butterflies?

colourful, scented petals attract insects

large, sticky pollen grains become attached to the insect’s body

nectar, a source of food for insects, is deep within the flower

stiff anthers and stigmas are positioned where insects must brush past them

Adaptations for wind pollinationHow are flowers adapted for pollination by the wind?

small, dull-coloured petals

anthers hang loosely outside flower so wind can blow pollen

huge numbers of light, tiny pollen grains

long, feathery stigma hanging outside flower so pollen can be trapped

Plants can live in acid or waterlogged soils where there is little nitrate. Some plants have evolved a rather cunning adaptation to obtain the nutrients they need.

Hairs on the slippery inside of the plant are angled down to ensure that the victim cannot escape!

Pitcher plants have a large hollow filled with fluid that traps insects or other small organisms that may fall in.

The plant digests its victims to absorb the nitrates it needs!
