Question

“Any disturbance in the life cycle can create an ecological crises” – Explain the statement.

Answer 1

• If a particular species feeds upon a particular kind of plant is exterminated, it would result in unchecked growth of that plant. 
• Then that plant may intrude into the area of other plants and stop their growth. 
• Many industries release their chemical wastes into the rivers and streams. 
• These chemicals like mercury are consumed by micro organisms and in turn, become the food offish. 
• When human beings consume these fishes they too absorb mercury which is detrimental to their health. 
• Thus we can say any disturbance in the life cycle can create ecological crises.
