Living organisms capable of synthesizing food on their own are called as plants. They contain chlorophyll, the green magnesium compound which helps in trapping the energy from sun. This energy runs the process of photosynthesis through which glucose is basically synthesized in leaves and green stems on combining together the atmospheric carbon dioxide and water.
The balance of nature is maintained by its different components -living and non-living, if they remain unaltered by human beings.

Living beings interact among themselves in the same species, with the members of the other species, and with the components of the abiotic environment in an ecosystem. Interaction between the members of the same species is called as Intraspecific whereas the interaction among individuals of different species is called as Interspecific.
The positive movements of a plant shoot in response to light or movement of shoot towards the source of light is called as Phototropism. If the part of a plant moves away from light, this movement is called as Negative Phototropism.

Many squirrels had made nests in upper portions of offices by depositing huge balls of wool like materials between the rows of files and old registers. Many times and many men spotted some or the other squirrel coming to the rows of files and registers placed there since many-many years. But since squirrels usually don’t destroy papers, as I think, nobody ever tried to disturb them.
The biosphere is itself a vast ecosystem which incorporates all the small ecosystems. But, the biosphere may have different types of physical conditions, communities of plants and animals, and climatic conditions in its different zones.
