    Hello. I have a couple of questions to ask you. 1.Why do plants need the sun? 2. What would the affect be on the plant if there wasn't sunlight? 3.Do plants find sunlight or does the sunlight find the plant? 4. Does every plant need the sun? 5. Would it affect the ecosystem if there was no sun?

    Answer

    Plants use sunlight to make food. The green pigment (cholophyll) uses the energy from the sun to combine with CO2 (carbon dioxide), water, and nutrients/minerals to create the food that nourishes the plant. Without sunlight, the plant cannot manufacture its food and it would diet. Plants find the sun, and often grow in a direction to reach more of it. Not all plants need the sun, some parasitic plants get their food from other green plants (or from fungi). Without the sun, almost all life (not just plant life) would eventually end.
