Answers
1) Reproduction is the process by which new individuals are produced by the parents. The process of reproduction ensures that a plant or animal species does not disappear from Earth. This process is very important in maintaining stability in the ecosystem and for the continuation of life on earth.
Answer:
1.reproduction is essential for organism because new is formed by reproduction if their is no reproduction the life would come to an end.
2.sexual reproduction is better mode of reproduction because off spring promotes the diversity of character of both parents due to combination of genes but in asexual evolutionary changes can not accur because of one parent therefore no variation occur.
