Man tough call I between b and d. But I might go more for B by the fact that the population will be increasing.
Hope this helps!
Answer:
The correct answer will be - the sugar is not transported to roots
Explanation:
The girdling is performed on tress by making a groove of 1 cm in the bark of a tree.
The girdling activity removes the phloem tissue of the trees which help in the conduction of the sugar and other useful nutrients in the trees.
Since the phloem is present on the outside portion of the vascular cambium due to the secondary growth, therefore, removing the bark and making a groove in the tree removes the portion of the phloem. The removal of the phloem stops the blockage of the sugar to the roots as a result of which the root dies and water is not absorbed. This leads to the death of the tree after some time.
Thus, the sugar is not transported to roots is the correct answer.
Answer: Coal
, Wood, Wind turbines
Explanation:
Coal is a nonrenewable resource. It can be used for the generation of electricity as the burning of the coal as fuel liberates immense heat energy depending upon the carbon content of the coal. The amount of energy liberated by the coal depends upon the type of coal used hence, the energy yield can remain unpredictable. Wood is the source of biomass energy. It can be burned upon to obtain heat energy. The energy produce depends upon the carbon content and weight of the wooden logs used.
The energy harnessed by a wind turbine is also unpredictable because in a hot humid day and a wet rainy day wind energy cannot be captured.
