Analyzing Statements About the Biosphere
This question asks us to evaluate several statements concerning the 'Biosphere' and identify the correct ones. Let's break down each statement to understand its validity.
Statement A: 'Bio' is a Greek word meaning life
The word 'Bio' originates from the Greek word 'bios', which indeed translates to 'life'. This prefix is used in many scientific terms related to life, such as biology, biography, etc. Therefore, statement A is correct.
Statement B: Biosphere is an integral part of the Earth system which supports all kinds of life
The Biosphere is defined as the zone of Earth where life exists, encompassing all living organisms—plants, animals, and microbes. It interacts with the physical environment (atmosphere, lithosphere, hydrosphere) and is crucial for supporting life. Thus, it is an integral part of the Earth system. Statement B is correct.
Statement C: All the biological components of the Earth living as well as the dead, fall in the category of biosphere
The Biosphere includes not only currently living organisms but also the remnants and products of past life, such as dead organic matter, fossils, and decomposed material. These are all considered biological components within the scope of the Biosphere. Therefore, statement C is correct.
Statement D: The term 'Biosphere' has been coined by Peter Suess
Historical records indicate that the term 'Biosphere' was first popularized and defined in a scientific context by the Austrian geologist and paleontologist Eduard Suess in the late 19th century. While Peter Suess might be a related or confused name, Eduard Suess is credited with coining the term. Therefore, statement D is incorrect.
Conclusion on Statements
Based on the analysis above:
- Statement A is correct.
- Statement B is correct.
- Statement C is correct.
- Statement D is incorrect.
Therefore, the correct combination of statements is A, B, and C.
