Natural selection affects the scope of the niche of a given species. Moreover, trade-offs are associated with differences in traits that also may affect the niche of a species.
<h3>Natural selection and trade-offs </h3>
Natural selection refers to the differential survival or reproduction of individuals in particular environmental conditions.
The different niches occupied by species are mainly a consequence of differential trade-offs among species, i.e., by differential phenotypic features that generate negative correlations among species.
Grime’s Triangle is based on the associations (trade-off) between adaptation to productivity and/or competition, stressful environments (habitats) and disturbance.

Climate change due to the greenhouse effect.
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.
