Answer 2

Green plants have a pigment called ChLoRoPhYlL which provides green colour to the leaves. Through chlorophyll plants are able to prepare their own food as well as for others as we all our interdependent on each other directly and indirectly , through a process called Photosynthesis. If there will be no green plants left then other creatures on earth will die simultaneously as plants are a basic and important source if life. Since plants will not be able to produce food, so we all humans will also die as plants too take in CO2 and release out O2 which will decrease if plants will be decreased and hence humans and other creatures will die.
