    Forests are called the green lungs of nature as they release oxygen during the process of photosynthesis. This oxygen is used up by animals including man for respiration. Thus forests maintain balance of oxygen and carbon dioxide in the atmosphere.

    A forest has different types of plants like herbs, shrubs and trees. It also has many type of tall grasses, canes, creepers and climbers. 

    Forests have perennial trees of Sal, Sheesham, Teak, Banyan, Neem, Peepal, Bamboo, etc.

    A forest has annual, biennial and perennial plants. Herbs are mostly annuals with a life span of one year. Biennials have a life span of two years whereas perennials can survive for several years. These include shrubs and trees.

The heart has 4 chambers. The 2 upper chambers are called artium and the 2 lower chambers are called ventricals. The portion between the chambers avoids the o2 rich in blood mixing up with co2 rich in blood.the rythmic beating of various chambers maintain the circulation of blood.

    Tropical rainforests have four layers:

    Emergent Layer:
    These giant trees thrust above the dense canopy layer and have huge mushroom-shaped crowns. These trees enjoy the greatest amount of sunlight but also must endure high temperatures, low humidity, and strong winds.

    Canopy Layer:
    The broad, irregular crowns of these trees form a tight, continuous canopy 60 to 90 feet above the ground. The branches are often densely covered with other plants (epiphytes) and tied together with vines (lianas). The canopy is home to 90% of the organisms found in the rain forest; many seeking the brighter light in the treetops.

    Understory:
    Receiving only 2-15% of the sunlight that falls on the canopy, the understory is a dark place. It is relatively open and contains young trees and leafy herbaceous plants that tolerate low light. Many popular house plants come from this layer. Only along rivers and roadways and in treefall and cut areas is sunlight sufficient to allow growth to become thick and impenetrable 

    Forest Floor:
    The forest floor receives less than 2% of the sunlight and consequently, little grows here except plants adapted to very low light. On the floor is a thin layer of fallen leaves, seeds, fruits, and branches that very quickly decomposes. Only a thin layer of decaying organic matter is found, unlike in temperate deciduous forests.

    Motion in a straight line is nothing but Linear motion. As the name suggests, it’s in a particular straight line, thus it can be said that it uses only one dimension.

    The linear motion, also called the Rectilinear Motion can be of two types –

    1. Uniform linear motion with constant velocity or zero acceleration
    2. Non-Uniform linear motion with variable velocity or non-zero acceleration
