biological variety of species and plants
Name 3 adaptations of plants in the rainforest
- Thick waxy leaves
- Buttress roots
- Lianas (climbing plants)
Name 3 adaptations of animals in the rainforest
- Flaps of skin enabling gliding
- Camoflague
- Strong limbs
What’s the purpose of thick waxy leaves
The pointed tips and wax allow surface run off meaning the plants aren’t damaged and don’t grow fungi
What’s the purpose of Buttress roots
Support the trunk of trees so they don’t fall over. Also help CO2 intake due to large surface area
What is the purpose of Lianas
Climb up to the sunlight for photosynthesis
What is the purpose of skin flaps
Enable animals to glide from tree to tree to escape predators and travel quickly
What is the purpose of Camouflage
To hide from predators
