How is a plant's growth affected when it is over crowded?

Answer:
Plants tend to grow long and spindly as they are trying to reach the light. Growth can be stunted because there is more competition for the available nutrients and water. Plants can be more susceptible to diseases and insect attack because they are in a weakened state.
