How can oxygen deficit be minimised pe

Answer 1

Lactic acid is a by product of exercising without using oxygen (anaerobially). It is essential this is removed but it is not necessarily a waste product. It is recycled into other useful chemicals

Answer 2

Let me give this a try;

• Oxygen is a very important aspect to the life of any plants or the  humankind. and therefore it supply should be made constant.
• The planting of many trees is one of the ways of curbing the oxygen deficit in our ecosystem,.
• This is because during the day plants takes in carbon dioxide for photosynthesis and gives out oxygen for respiration.    
• This shows the role of trees in the supply of oxygen in our ecosystem.
