5. In environment other organisms get food by reproduction – false
6. Reproduction is seen only in animals – false
7. There will not be any danger in Environment by over reproduction of a single organism – True

12. Observe these pictures, which living characteristic that these creatures indicate?

Answer:In the above picture, all are living organisms and they are capable of movement. Movement is a very important feature of all living organisms.

2.	In environment other organisms get their food by reproduction	Right	Because reproduction of one organisms gives food for its predators
3.	Reproduction is seen only in animals	Wrong	Reproductions is seen in all living organisms
4.	There will be no danger in the environment by over-reproduction of a single organism.	Wrong	Over-reproduction of a single organism causes shortage of food resulting in the competetition for food. Sometimes the weaker animals die when they can’t get enough food.

18. Reproduction of plants is advantageous to animals including man in many ways, how?

Answer:Plant reproduction is a vital food source for other organisms. They give us fruits, seeds, and vegetables. They also give us a lifeline for animals-oxygen; therefore, reproduction of plants is advantageous to animals

19. Observe the figures, how organisms respond to stimuli?

Answer:When we touch a touch me not plant, the leaves get folded immediately as a response to the touch. Scorpion gives a sharp sting when we try to touch them.

20.Write the uses of annuals, biennials , perennials.

Answer: Annuals growth cycle lasts for one complete year with an extended blooming period. They are sweet-scented whereas biennials can survive up to two years, examples; parsley, fennel, Lunaria, silverbeet. Perennials have a long life yielding crops for many years for example; herb gardens and fruit trees.
