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.
Anthills show the quality of soil.
A substance, factor, change, living being or a system that quantifies and simplifies phenomena and helps in understanding complex realities, is called as indicator.
It tells us something about changes in a system. There are many types of indicators some of which are- Financial Indicators, Poverty Indicators, Health Indicators, Environmental Indicators, and Indicators of Sustainable Development.
Landslides are very common in rainy season. Rains caused serious conditions during previous some weeks this year in many villages of Maharashtra. Many of these villages that were located in the laps of mountains vanished within no time.
Cauliflower is a beautiful compact snow ball like vegetable if it is white. It remains surrounded by soft and long foliage.
A group of individuals of a particular species occupying a particular area at specific time is called as population.
Water is the principal constituent of our body. Water is chemically an inorganic, transparent, tasteless, odourless, and colourless. It is the main constituent of the hydrosphere of the earth.
Everyone wishes to increase his body immunity in the current fearful period of corona. Earlier, very few talked about immunity and no- one probably ever talked to make efforts for increasing it.
Living beings in environment like animals and plants constitute more than half of the environment in the biosphere. All of these need to be conserved.
The environment of our earth has a number of life zones that support birth and development of all types of organisms.
All the life zones of the earth are collectively called as Biosphere.
The biosphere vertically extends into the atmosphere up to about 10 km and downwards into the oceans up to a depth of about6.9 km.
In human beings reproduction takes place through the activities of male and female reproductive organs. To understand this, it is essential to study the structure of male and female reproductive systems separately.
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
