(elements,chemicals, temperature,sunlight/irradiation)

Answer 1

Answer =

Requirements for life in earth are necessary are as follows:

Elements = the life on earth consists of many organisms and each and every organism contains relatively large amounts of elements almost 25 elements .like as Oxygen, carbon, hydrogen,nitrogen and sulphur make up about 96 % of human body.

sodium, magnesium, potassium, calcium, chlorine and phosphorous are macroelements.

Chemicals - all processes on earth consists of chemical reactions.liquid water is an essential requirement for life on earth. water is called as universal solvent because of its properties like as it acts as solvent for many solutes.

Temperature - it is an important factor , because temperature keeps the water in liquid state.and life without water on earth can not be complete.life can grow and reproduce at temperatures as low as -150C, and as high as 1220C.

all processes that is chemical reactions which occure in living organisms needs the enzymes and each and every enzyme requires a certain temeperature to catalyze that reactions.

Sunlight/ irradiation - Sunlight is essential requirement for life on earth. Plants absorb the sunlight and conducts the process of photosynthesis . through photosynthesis plants are capable to produce food material. they can provide food to all other living things.
