Answer:
Option A
Explanation:
Options -
A-avoid water pollution.
B-build thermal power plants.
C-add water features to gardens.
D-avoid drip irrigation systems
Solution -
The largest source of freshwater on planet earth is underground water. The water beneath the surface of earth is very limited. The total fresh water reserve on earth is 3% of the total water on earth. Pollution due to discharge of waste water into the rivers and oceans has caused the degradation of not only surface water but also ground water.
Thus, option A is correct
Drip irrigation is a means to prevent wastage of water during irrigation. Thus, avoiding it will cause further loss of fresh water.
Addition of water feature will increase usage of water, thus it is also incorrect
Building thermal plant will also cause water pollution and wastage. Hence, option B is also incorrect
The right answer is A. producer.
Phytoplankton are all cyanobacteria and microalgae (microscopic plants) present in surface waters and drifting with the currents. Unknown because invisible to the naked eye, phytoplankton is the lung of our planet. Thanks to photosynthesis, it produces more than half of the Earth's oxygen and consumes half of the carbon dioxide. Phytoplankton is essential for marine life because it is also at the base of the ocean food chain.
Answer:
The correct answer will be- light independent reaction or Calvin cycle
Explanation:
The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.
The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.
The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.
Thus, the Calvin cycle is the correct answer.
