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.
Chapter 9 The Living Organisms and Their Surroundings
- Different kind of plant and animals living in a different kind of habitat.
- Human and animals collectively known as organisms.
- According to their habits and surrounding environment, an organism lives in a specific habitat.
- The place where organism live called its habitat.
- The plants and animals which lives on land called terrestrial habitat and those who lives in water are called aquatic habitat.
- All the living and non- living things in the environment is known as biotic and abiotic components respectively.
- All the living things or we can say organisms shows some properties like growth, respiration, reproduction, respond to stimuli, communication and shows movement.
- When an organism change its habit or adapt itself according to the surrounding environment is known as adaptation.
