Deciduous Forests


This picture represents a part of a deciduous forest. This can be deduced from the fact that the leaves of the trees have changed their color. It is characteristic of deciduous forests to change their leave’s color in autumn and shed them in the winter (Hurtig, 22). In fact, the trees have already started shedding leaves which have already fallen on the ground. Therefore, it has been established that this is an autumn day. Deciduous forests are normally found above tropical forests but below coniferous forests on latitudinal levels. Therefore, deciduous forests are widespread in North America in the northeast part of the USA, the mid part of Europe, New Zealand, Japan, South East Australia, Southeastern Russia, and Eastern China (Hurtig 34). This means that this picture must have been taken from one of these regions. These regions receive a rainfall of about 75 to 150 cm per year and experience an average temperature of 10° C. In these regions, all the four seasons can be witnessed. Winters are frosty and cold, summers are humid and hot, autumns are breezy and cool, and the springs breezy and warm. The process of shedding leaves is a biological principle.

There is a lady sitting in the shade of the trees. This is also a biological process that uses biological principles

Why Do Trees Shed their Leaves?

Plants during the winter are at risk of losing moisture due to the harsh, cold, and dry winters that sweep the deciduous regions. Trees adapt to this by shedding their leaves and going through a dormant state. This allows the plant to conserve most of its energy through the winter. During the autumn, the length of the day has already started reducing, and the plant is exposed to very little sunlight. This results into the plant producing little chlorophyll which is the green coloring matter; thus, trees’ leaves turn their color to red, orange, and yellow. The tree then produces some chemicals such as the ethylene or abscisic acid which cuts the leaves off the twigs and branches. These leaves only appear in the spring when there is sufficient sunlight. The leaves also form mulch over the trees’ roots preventing the roots from moisture loss.

The abovementioned chemicals, abscisic acid and ethylene, make trees shed their leaves breaking the link between the tree and the leaf.

How Do Animals and Plants Interrelate in Oxygen and Carbon (IV) Oxide?

The lady sittiing under the tree forms a symbiotic relationship with the trees. She gets a shade and oxygen needed for her respiration. This is true because plants during the day take in carbon (IV) oxide for photosynthesis and give out oxygen. On the other hand, the lady’s respiration process coupled with the body’s metabolism takes in oxygen and produces carbon (IV) oxide. This creates a cycle where the trees and the lady exchange needed gases for their respiration.
