-Photosynthesis is the process by which plants make their own nutrients using energy from the sun light. Solar energy from the sun together with water, carbon dioxide are used to make organic compounds such as glucose and oxygen as a by product.
-Cellular respiration involves the break down of nutrients such as glucose to yield energy in form of ATP, that is used by the cells to drive cellular processes, such as transport and growth.
-In both of the stages of photosynthesis and in aerobic respiration, glucose is the energy used to create ATP.
Population density =number of individual divided land area land area should be in square kilometers therefore 120 ha =120 x0.01=1.2 square kilometer since 1 ha=0.01 kilometer square total population= (80 x 1500)/100=1200 population density is therefore=1200/1.2=1000
