The pyramid of energy represents the total amount of energy consumed by each trophic level. An energy pyramid is always upright as the total amount of energy available for utilisation in the layers above is less than the energy available in the lower levels. This happens because during energy transfer from lower to higher levels, some energy is always lost.

Arbor Day is an annual observance that encourages individuals and groups to plant and care for trees. It originated in the United States in the 19th century.

It is the meristem, that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common at the nodal regions. It may also occur at the base of the leaves. The intercalary meristem also contributes, towards the increase in length, as it brings about elongation, of the internodal regions. It is also responsible, for the formation of branches, at the nodal regions
