Answer:
ENERGY:
DEFINITION:
"the ability of a body to do work is called energy"
"why do living organism need energy"
we know that in daily we perform various functions/activities .e.g walking , writing etc and for all these things doing energy is needed.because without energy we are not able to perform various activity .e.g anabolism and catabolism and many other reaction will not take place in our body cell. so, it may result abnormal condition to the body.therefore energy is necessary for life.
SUN: sun is the ultimate source of energy.light comes from sun to plants on the earth and plant capture the light and form glucose in the presence of chlorophyll , water sunlight and carbon dioxide.as a result oxygen is produced as a byproduct and hypertrophic use this or inhale this and this oxygen help us in respiration and in the result of respiration energy is released which is necessary for life activities
Note:carbon dioxide is released or produce during respiration and is used by plant in photosynthesis
