Morphological adaptation is a structural change which gives an organism a greater chance of survival in its habitat.

The Fennec fox lives in the desert. Its structural adaptation is to have large ears. This allows heat to be radiated from the body helping to cool it down.

By contrast, the Arctic fox lives in a cold habitat. It has smaller ears and thick fur in order to retain its body heat.

Behavioural adaptation is the way an organism reacts to its environment which aids its survival.

The pangolin is a nocturnal animal, which means it is active during the night. This behaviour is an adaptation to the desert-like habitat in which it lives. It is too hot to hunt during the day so they hunt for food at night.

The pangolin is an endangered species. This means the numbers of pangolins found in the wild are decreasing and if this continues it may become extinct.

Biodiversity and endangered species can be conserved and protected by:

• the Convention on International Trade in Endangered Species (CITES)
• Sites of Special Scientific Interest (SSSI)
• captive breeding programmes
• national parks
• seed/sperm banks
• local biodiversity action plans
