How has the Douglas-fir adapted to enable its survival in the taiga biome?
a.
low growing
b.
perennial
c.
waxy needles
d.
survive on limited nutrients

Answer 1

c. waxy needles

The waxy cuticle on the needles reduces water loss and helps protect the leaves from freezing and desiccation in the cold, dry taiga, allowing the tree to photosynthesize year-round.
