13adaptations =
features that help animals survive in their habitats
14how are camels adapted to hot deserts
large feet, leather kneepads, bushy eyelashes, fat stored in hump, spit stomach out, strong thighs, thick coat to stop burning

32def of deforistation
the cutting down and removal of trees
33why are tropical rainforest important for biodiversity
as they contain 50% of existing plant and animal species in the world and without rainforest we would lose a significant amount of wildlife some of which haven't been discovered

increase of jobs
36sustainability =

47which layer can you find saplings in and what are they doing
under canopy - wait for larger plants and trees to die,leaving a gap where they can grow
