I dont know......lolzzzz....!! :p

In terms of climate, deciduous forests are found mainly in moderate and tropical areas, while evergreen forests, also known as coniferous forests, are found in colder climates, both in terms of latitude and elevation. Evergreen forests are more adapted to harsher conditions in the form of lower amounts of sunlight, stronger winds and colder temperatures. Deciduous forests are found mainly in areas that experience seasonal changes through the year, which explains the loss of leaves in the fall and new growth and buds in the spring. In many areas where a moderate climate prevails, mixed-deciduous forests contain a combination of evergreens and deciduous trees.

Plant Adaptations

In each of the two forest types, trees and plants adapt to meet the conditions of the area's climate. Coniferous evergreen trees typically have rounded needles for leaves and branch patterns that are able to support the weight of snow during winter. Many evergreen trees also produce a biochemical antifreeze-type substance that helps to maintain basic life supporting functions during sub-freezing temperatures. Deciduous trees have broader leaves and more chlorophyll than evergreen trees in order to catch as much sunlight as possible during the warm season before they lose their leaves during winter. Deciduous trees are also able to seal off old buds with a protective covering during the winter to combat freezing temperatures.

Soil

The soil in a deciduous forest is notably richer and has a thicker organic layer than an evergreen forest. Fallen leaves in a deciduous forest are broken down, returning more nutrients to the soil; these nutrients are used by other plants in the understory. Typically, because of the deciduous forest's rich soil, there are several layers of plants between the main canopy and the forest floor. However, in an evergreen forest, old needles from evergreen trees make up a thin covering of the forest soil. The needles from an evergreen tree are typically acidic, making for a nutrient-poor soil. As a result, fewer understory plants are able to grow in an evergreen forest.

Biodiversity

One of the biggest differences between an evergreen and a deciduous forest is the amount of biodiversity found in a deciduous environment. Several different types of mammals live in deciduous forests; these are nut and acorn feeders, herbivores or omnivores. Some deciduous forest regions, such as the Great Smoky Mountains in North Carolina and Tennessee, have some of the richest biodiversity of plants, salamanders and slime molds in the world. On the other hand, fewer animals and fewer types of plants are able to survive the climatic extremes of the northern evergreen forests. These animals have made special adaptations to the cold. They include elk, caribou, reindeer, rabbits, squirrels and predators such as the lynx, wolverine, bobcat and wolf.

Evergreen Forests	Deciduous forests
Tropical evergreen forests are found in those regions which receive more than 200 cm of rainfall.	Deciduous forests are found in the regions which receive rainfall between 200-70 cm.
The trees of the tropical evergreen forests do not shed their leaves at a same time as there is no particular season for shedding their leaves.	The trees of the deciduous forests shed their leaves for about six to eight months during the dry season.
Tropical evergreen forests are dense.	These forests are less dense.
These forests are found in the Andaman and Nicobar Islands, Lakshadweep, upper parts of Assam and Tamil Nadu and on the western slopes of the western Ghats.	These forests are found in North-eastern states, parts of Central India, West Orissa and Chhattisgarh.
Some of the species of the trees in these forests are ebony, mahagony, rosewood and rubber.	Some of the species of the trees in these forests are sandalwood, teak and sal.

Deciduous and evergreen are two opposite types of trees. They are categorized by the pattern and seasonality of their foliage growth. Plants between deciduous and evergreen are known as semi-deciduous trees. They have characteristics of both. In this article, we’ll tell you the main differences between an evergreen and a deciduous tree.

What are deciduous trees?

Deciduous is a term that refers to trees which seasonally shed their unnecessary parts, such as leaves, from their structure. Most deciduous trees are broad leaf trees. Because of the structure of the leaves and the pattern of leaf arrangement, the effectiveness of photosynthesis is very high in deciduous trees. Unfortunately, deciduous trees have both positive and negative aspects to them. Since they shed their leaves seasonally (during autumn and winter usually), they are very susceptible to wind and other winter weather conditions.

The falling of the leaves helps them prepare for winter conditions. It ensures better survival in winter as well as high water conservation and protection against predatory actions. Deciduous tree characteristics are observable in many woody trees like oak and maple. There are two characteristic deciduous forests where the majority of trees shed their foliage at the end of their typical growing season. These are temperate deciduous forests and tropical (and subtropical) deciduous forests. Trees in temperate deciduous forests are sensitive to the seasonal temperature variations whereas the tropical deciduous trees respond to seasonal rainforest patterns.

What are evergreen trees?

The evergreen tree is a complete contrast to the deciduous tree. As the name implies, an evergreen’s foliage remains on the tree throughout the entire year. There is no seasonal leaf shedding. Evergreen plants have a huge deviation within them. They include most conifers and angiosperms such as hemlock, cycads, and eucalyptus trees.

This does not mean that evergreens never shed their foliage. Old leaves of evergreen trees are replaced by new growth as they age. Evergreen trees favor warm, temperate climates. Many tropical rainforests are considered evergreens.

What are the differences between a deciduous and an evergreen tree?

There are several important differences between a deciduous and an evergreen tree. We will list them for you here:

Deciduous and evergreen trees are opposite each other. Deciduous trees shed their leaves seasonally and evergreen trees keep their foliage throughout the year.
Deciduous trees are adapted to tolerate cold and dry weather conditions by shedding their leaves while evergreens do not.
Evergreens can survive with low soil nutrients. A huge portion of internal nutrients is removed during the defoliation of deciduous trees.
Nutrient requirements of evergreens are somewhat higher than those of deciduous trees during bad weather because of the need for foliage maintenance. In deciduous trees, it is high after harsh weather when the foliage is renewed.
Deciduous trees are more sensitive to temperature and rain fall than evergreen trees.

There are a number of organizations and groups that are dedicated to helping protect the Amazon rainforest and raising awareness about the issue of deforestation.? The World Wildlife Fund is working to create partnerships with local governments and groups to help secure land rights, enforce best management practices, and ensure infrastructure development has as little lasting ecological impact as possible.? National Geographic Magazine has featured the Amazon a number of times, including the article cited below that helps people outside the situation become aware and do what they can to help protect it.This interesting target sport illustrates another good example of mechanical energy and the work done by the object possessing it. The bowling ball consists of some amount of energy in the form of kinetic energy as soon as it starts rolling towards the target. Due to this energy, the ball has the ability to do work on the pins. When the ball hits those target pins, it (ball) applies force (in the form of mechanical energy) and displaces them, hence, causing work to be done. Therefore, here also, we can say that mechanical energy gave the bowling ball the ability to do work on the pins that caused their displacementWindmills are the structures that convert wind energy into electrical energy and this energy is then supplied to our homes. But from where does this energy in the wind comes and moves the large blades of a windmill? Windmills run on the principle of mechanical energy and work. Moving air (wind) possesses some amount of energy in the form of kinetic energy (due to motion). This energy gives the air the ability to do work on the blades of the fan. The moving air applies force on the blades and enables the work to be done, hence, resulting in their rotation. Therefore, the mechanical energy gave wind the ability to do work on the blades of the fan.
