Answer:
Experimentation
Explanation:
The loblolly pine tree is a member of the yellow pine group which is grown in plantations for commercial production of timber.The tree itself can reach a height of 40 meters with a truck of 1 meter in diameter.Pines have long needle-like leaves held in bundles. A researcher can measure the length of the needles, count the number of needles in a bundle, and measure the length of the sheath.Loblloly pine needles measure up to 17 cm long.The researcher can also weigh a bundle and determine the weight of the needles.This is field experiment that will require a measuring device for weight and length so observation alone won't provide the needed data.
Answer:
The correct answer will be- both observation and experimentation
Explanation:
The determination of length and weight of the pine trees of the forest can be determined by the scientific method.
The observation must be done to measure the length and weight of the trees using the instruments whereas the calculation of the measurement must be done through a systematic approach to calculating the average.
Both observation and experimentation are steps of the scientific method which can lead to the answer therefore, both observation and experimentation are correct.
