Answer 2

Heya !!

Plants are autotrophs ie they can manufacture their own food (due to the presence of light-absorbing pigment chlorophyll) through simple inorganic substances like carbon dioxide, water, sunlight ,soil etc.
Humans,on the other hand , are heterotrophs ie they can't synthesise their own food like plants do. Hence they consume plants and plant parts to obtain the food they require. In this way they depend on plants.
Also plants use the carbon dioxide exhaled by humans during photosynthesis to release oxygen which is essential for the survival of us humans.
This clearly shows their interdependency.



Hope that helps !!
