All these activities have disturbed the natural balance of our ecosystem and this imbalance falls heavily on us‚ human beings. The increased number of diseases that surround our bodies on all sides‚ pollution‚ and depletion of natural resources are all such aspects that cause a lot of harm to the living beings on this

of the interrelationships or interactions among the different components of the ecosystem. All the ecosystem components are directly and /or indirectly linked with one another. “There is constant interchange of various kinds within each system‚ not only between the organic and inorganic” (Tansley‚1935). The linking forces are two processes: the energy flow process‚ and the biochemical cycle. In other words‚ ecosystem components are linked to one another by the transfer of energy and nutrients via

A species is a group of organisms that are able to produce fertile offspring and share common genes. 4.) Describe the different sources of energy for an ecosystem.

Anything which we eat to live is called food. Food contains energy. The food (or energy) can be transferred from one organism to the other through food chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants. So‚ we can say that all the food chains begin with a green plant (or grass) which is the original source of all food. Let us take an example to understand the meaning of food chain. Suppose there is a field having a lot of green

In acknowledgment of this‚ the United Nations’ Kofi Annan presented a report: “We the Peoples: The Role of the United Nations in the 21st Century.” (2000) Annan called for Millennium Ecosystem Assessment in order to establish the consequences of change in ecosystems for the well-being of humans‚ and to specify the importance of conservation

I. Lecture A. How do human actions disrupt the proper functioning of ecosystems? There are two ways that humans disrupt the proper functioning of ecosystems. One is by altering the structure of natural landscapes. Tearing down trees‚ which can be homes to different wildlife species‚ can do this. Another way humans disrupt the functioning of ecosystems is by altering soil composition. B. What is ecosystem stewardship? Ecosystem stewardship is an action-focused framework intended to promote the social-ecological

Wetlands are the link between land and water and are some of the most productive ecosystems in the world. Depending on the type of wetland‚ it may be filled mostly with trees‚ grasses‚ shrubs or moss. An area doesn’t need to be permanently wet to qualify as a wetland. It just needs to be wet long enough for its plants and animals to be
