Chapter: 01. Living And Non Living Things
Section A: Multiple Choice Questions (MCQs)
b) Sunlight, air, and water Section B: Fill in the Blanks
Section C: True or False
Section D: Explain the Terms
Spiracles: Tiny air holes present on the bodies of insects that help them to breathe. Stomata: Pores on the underside of leaves of plants through which they take in and give out air. Reproduction: The ability of living things to give birth to their own kind. Section E: Short Answer Questions
Three characteristics that differentiate living things from non-living things are: living things need food and water, they can grow, and they can reproduce. Living things need food to get energy for all their activities, to stay healthy, and to help them grow. Two human-made non-living things you might find in a park are a bench and a swing set. (Other valid answers: slide, car, ball, trash can). Animals use their sense organs in many ways. For example, a dog uses its nose to sniff out food, and eagles use their good eyesight to spot prey from far away. Section F: Diagram-Based Question
The characteristic of living things being shown in this series of pictures is growth. In the sequence, a small seed (picture 1) first sprouts (picture 2) by emerging from the ground. Then, it develops into a young plant with a few leaves (picture 3). Finally, it grows into a larger, mature plant with many leaves and flowers (picture 4). Section G: Identify and Differentiate Concepts
Togo (the dog) is a living thing, and Barky (the toy dog) is a non-living thing. Another difference is that Togo needs food, air, and water to survive, but Barky does not need any of these. Section H: Long Answer Questions
Living things can sense and respond to changes in their surroundings. For example, when a human touches something hot, they feel pain and quickly pull their hand away. Animals like eagles use their sharp eyesight to detect prey from a distance. Plants also show this ability; the leaves of a ‘touch-me-not’ plant will close up when touched, demonstrating a response to physical stimulus. Plants and animals differ significantly in how they obtain food. Plants are unique because they can make their own food using sunlight, air, and water through a process called photosynthesis. They are producers. In contrast, animals cannot make their own food; they must consume other living things. Some animals eat plants, while others eat other animals, making them consumers in the food chain. Section I: Environmental Awareness / Everyday Use
I would disagree with the statement. While the river’s water is moving, it does not move on its own in the way living things do. The water moves due to forces like gravity or wind, and it does not possess other characteristics of living things such as needing food, breathing, growing, feeling, or reproducing.
