2) Environmental sphere refers to all the materials that are present in the environment. There are five sphere which are given below.
1) Lithosphere: This sphere comprise of land on which all living organisms lives.
2) hydrosphere: It refers to water bodies.
3) biosphere: It is the living part of the environment.
4) atmosphere: This sphere contains gaese which are necessary for survival.
5) cryosphere: This sphere contains water in stored form.
3) A cycle in which chemical moves from living and non living things to the atmosphere.
1)carbon goes to the atmosphere through respiration and burning of fuel.
2) phosphorus is released after the burning of plant body.
3) nitrogen is released in denitrification process and industries.
4) oxygen is released in the atmosphere through photosynthesis.
5) sulfur is released in the atmosphere through volcanic eruptions.
