which are considered as the biological components in a biosphere physical components?

The environment in which the man and other organisms live is called the biosphere. The biosphere is made up of different regions that have different types of flora (plants) and fauna (animals). The types of organisms in an area are determined by various factors such as the clim..

Each and every living organism has its specific surrounding medium of environment with which it continuously interacts and remains fully adapted. The environment is the sum total of physical and biotic conditions influencing the responses of the organisms. The life supporting environment ..

An ecosystem can be defined as 'a structural and functional unit of biosphere or segment of nature consisting of community of living beings and the physical environment, both interacting and exchanging materials between them'. E. P. Odum, an American ecologist, defined ecology a..

In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transport nutrients and wastes. ..

Let us consider a body of mass 'm' being raised vertically to a height 'h' as in the figure (1). The work done is mgh. Suppose we take the body along the path as in figure (3). The work done during the horizontal motion is zero. Adding up the work done in the two vertical parts of the pat..

. Let us consider the case of angular momentum in two dimensions. L = xp y - yp x If j is the angle between and x-axis, then p x = p cos y and p y = p sin y. Also x = r cos q , y = r sin q . Hence, we can define angular momentum as the product of linear momentum and the lever arm for mome..

Consider a body placed on a platform whose angle with the horizontal can be changed for e.g., a tipper with stones at the back. The weight W can be resolved into two rectangular components. W cos f and W sin f . The component W ..

Fluids are substances which begin to flow when external force is applied on them. Liquids and gases are fluids. Fluids do not have a definite shape. The branch of physics, dealing with the study of fluids at rest is called hydrostatics. When fluids are kept in a container, due to random ..

Consider a thin long charged wire. Let the charge per unit length of the wire be l . To calculate the field at P we consider a Gaussian surface with wire as axis, radius r and length l as shown in the figure. This Gaussian surface that is, the cylinder is closed at each end by p..
