Answer:
3.) The giraffe has adapted by it's neck length increasing to reach the branches
4.) Biotic factors
Step-by-step explanation:
QUESTION 3: Due to the leaves growing towards the top of tree rather than around, the giraffes neck length impacts the access to the leaves, so they have adapted by increasing their neck length.
QUESTION 4: Giraffes and trees are both living things, therefore they are biotic factors.
