3. List any three adaptive features of the following:
a) Camel
b) fish
c) Cactus
Answers
Explanation:
Camel :
Large feet that helps them to walk on sand without sinking in.
Nostrils that the camel can open and close to keep out blowing sand.
Long eyelashes to protect its eyes from blowing sand.
Fish :
Fish have gills that allow them to “breathe” oxygen in water
Fish have a stream -lined body
Most fish have several fins for swimming.
Cactus :
Cacti have a widespread root system (made up of fibrous roots) that can allow them to collect water from a large area.
Root hairs grow on fibrous roots collecting even the smallest droplets of water. After the ground dries the hairs will die meaning the cactus wouldn't have to use extra energy to maintain them.
Cacti also have spines (the prickly thorn like things) in which replace leaves. These spines minimise the surface area of the cactus reducing water loss.
