Q4 Which of the things in the following list are nonliving? Plough, Mushroom, Sewing machine, Radio, Boat, Water hyacinth, Earthworm Ans: Non- living things: plough, sewing machine. Radio, boat, water etc.
Living things shows the characteristics like: growth, requires food for the energy, respiration, reproduction processes etc. above non- living things does not show any characteristics so they all are non- living.
Q5 Give an example of a non-living thing, which shows any two characteristics of living things. Ans: Automobiles like car, bus shows the characteristics of living things. Automobile show movement from one place to the other and they need energy to do the work. All electronic goods also shows the characteristics of living things.

These all are once a part of living beings like we get milk from cow. Then after the milk souring we get curd or butter. Leather is made up of animal’s skin. Wool is obtained from sheep. We get oil from the plants. Apple is obtained from the apple plant. Rubber is obtained from the latex, a milky liquid is present in the cells of the plants.
Q7 List the common characteristics of the living things. Ans: Some common characteristics of living things are:
- They shows growth
- Shows movements
- Maintenance of tissues and cells.
- Require energy to do work
- Shows respiration
- They all do reproduction
- They have senses.
- They respond towards the stimulus.
- They need all type of nutrients.
- Shows excretion.
Q8 Explain, why speed is important for survival in the grasslands for animals that live there. (Hint: There are few trees or places for animals to hide in grasslands habitats.) Ans: Speed is important for the survival in the grassland for the animals because in the grassland areas, carnivores and herbivores both types of animals lived there. Tiger is a top carnivore. Tiger eats other animals. So, if the herbivore animals have less speed then the tiger will eat them easily. But as in same condition, if tiger have less speed then he will die hungry. So speed is most important to the animals who lived in grassland areas.
