In 2010, you inserted a stainless-steel rod into a four-metre high *Eucalyptus regnans* at a point 1.5 metres above the ground. In 2021, you see that the tree has grown to 15 metres in height.

How many metres above the ground is the steel rod in 2021?

Justify your answer.

Answer :

Final answer:

The stainless-steel rod inserted into a Eucalyptus regnans tree remains in the same position of 1.5 metres above the ground in 2021 as it was placed in 2010, regardless of the tree's increased height. This is because trees' growth is in an upward position from their apex, not moving initial features or marks.

Explanation:

In biology, a tree, such as the Eucalyptus regnans in question, grows upwards from its apex, which is the highest point of the tree. New growth does not raise the level of initial features or marks on the tree. Consequently, if a stainless-steel rod was inserted into the tree at 1.5 metres above the ground in 2010, the rod's position remains at 1.5 metres above the ground in 2021, regardless of how much the tree has grown in height.

So, it doesn't matter that its height increased from 4 metres to 15 metres during these years; the rod remains 1.5 metres above the ground, not moving with the tree's upward growth.
