Pyramid of Biomass
The Biomass Pyramids show the amount of biomass (living or organic matter present in an organism) present per unit area at each trophic level. It is drawn with the producers at the base and the top carnivores at the tip.
Pyramid of biomass is generally ascertained by gathering all organisms occupying each trophic level separately and measuring their dry weight. Each trophic level has a certain mass of living material at a particular time called standing crop, which is measured as the mass of living organisms (biomass) or the number in a unit area.
Upright Pyramid of Biomass
Ecosystems found on land mostly have pyramids of biomass with large base of primary producers with smaller trophic level perched on top, hence the upright pyramid of biomass.
The biomass of autotrophs or producers is at the maximum. The biomass of next trophic level, i.e. primary consumers is less than the producers. Similarly, the other consumers such as secondary and tertiary consumers are comparatively less than its lower level respectively. The top of the pyramid has very less amount of biomass.

WATER, ENERGY, AND THE ENVIRONMENT

Man-Environment Relationship
Man and environment relationship is as old as the evolution of mankind. Since the evolution of man, the physical elements of the planet earth, such as terrain, soil, water, climate, flora and fauna formed man’s environment. During that time man was a typically a ‘physical man’ because of his limited wants, requirements, and total dependence on nature.
With the growth in social and economic activities, advancement in technologies, man expanded his own environment through design and skill to have provisions for improved and better food, shelter, access, and comfort or luxuries. Man’s ability to survive in a variety of ecosystem and his unique ability to adapt to a great variety of external conditions make man-environment relationship quite a fascinating area of study.
The environment in which man survives and to which he adapts himself and which he influences include physical, socio-cultural, and biological aspects. Man and environment has never been static and a great many factors are responsible for the shifts in man environment relationship.
Approaches to Man-Environment Relationship
The man and environment relationship can be studied under the following approaches.
Determinism − Friedrich Ratzel, the German geographer, was responsible for the development of the concepts of determinism, which was further expanded by Ellsworth Huntington.
This approach is based on the concept of ‘nature controls man’ or ‘earth made man’. According to this approach, man is largely influenced by nature. In fact, the determinism states that man is subordinate to natural environment because all aspects of human life such as physical (health and well-being), social, economic, political, ethical, aesthetic, etc. not only depend on but are dominantly controlled by the physical environment.
World famous biologist, Charles Darwin, in 1859 laid the foundation stone of the concept of environment influences on man and other organism.
Possibilism − Lucien Febvre, the French historian, founded the concept of Possibilism. Possibilism approach in the study of man-environment relationship is an offshoot of the criticism of environmental determinism and the impact of science and technology on such a relationship.
Possibilism indicates that the physical environment is passive and man is the active agent at liberty to choose between wide ranges of environmental possibilities. According to it, the pattern of human activity is the result of the initiative and mobility of man operating within the natural framework. Nowadays, the role of natural elements in conditioning, though not controlling human activities, is often lost sight of.
Possibilists were largely aware of the limitations of freedom of man to dictate terms to environment. It was agreed upon by the possibilists that man lacks the abilities to fully tame the nature and is not always victorious over it. As result of the above, some geographers vouched for ‘cooperation with nature’ or ‘mutual interaction’ between man and environment.
Ecological Approach − This approach is based upon the basic principle of ecology, which is the study of mutual interaction between organisms and physical environment on the one hand, and the interaction among the organism on the other in a given ecosystem. This approach describes man as an integral part of nature or environment. Man, being most skilled and intelligent, has a unique role to play in maintaining a natural environment as healthy and productive as it should be.
This approach emphasizes on wise and restrained use of natural resources, application of appropriate environmental management programs, policies and strategies keeping in view certain basic principles of ecology so that already depleted natural resources are replenished, and health and productivity of the nature is restored.

THE CULTURAL CONTEXT OF HOME CARE
Culture affects the day-to-day organization of care. Consider the idea of a partnership between families and nurses sought by home health care agencies. Agencies rightly recognize that optimal self-management of disease and a person’s return to function depends on a reasonable division of labor, shared information, and the willingness of family caregivers to learn rehabilitation and nursing protocols, medication administration, the use of assistive technologies, and the like (Wolff et al., 2009). But a family’s involvement may depend on how they define this partnership and, in particular, whether or not the home health care provider is considered part of the family (Knox and Thobaben, 1997; McGarry, 2009). Similar effects of culture may be evident in the willingness of families to accept telehealth technology, express their degree of burden or need for help, or seek hospice care at the end of life.

HOME CARE AND THE SOCIAL-ECOLOGICAL MODEL
The social-ecological model emerged from ecological systems theory (Bronfenbrenner, 1979), which explicitly sought to examine transactions between persons and their environments. The model stresses cross-level influences, in which community or organizational environments can shape individual behavior (top-down effects), but also examines how individuals form groups or take actions that may affect higher-level organizational or community spheres (bottom-up effects). The Centers for Disease Control and Prevention has incorporated social-ecological models into a number of its health promotion and disease prevention efforts.
The simple onion or Russian doll rendering of social-ecological relations as concentric circles is not in itself very informative. However, flowchart models based on such relationships can be useful for specifying hypothesized cross-level influences.

computer network
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
The nodes of a computer network may include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol.

The foundations of networking: switches, routers, and wireless access points
Switches, routers, and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Switches, routers, and wireless access points perform very different functions in a network.
