Living Things And Non-living Things

Explanation
The correct answer is dog, teacher, bird, flower, tree. These are the living things among the given options. A dog, bird, flower, and tree are all examples of living organisms. They possess characteristics such as growth, reproduction, and the ability to respond to stimuli. On the other hand, a book, house, and bag are inanimate objects and do not possess these characteristics. Therefore, they are not considered living things.

Explanation
A tree is a living thing as it belongs to the plant kingdom and exhibits characteristics of living organisms such as growth, reproduction, and response to stimuli. Unlike a bag, pencil, or computer, which are inanimate objects, a tree is a living organism that undergoes various biological processes.

Explanation
The statement is incorrect because a bag is an inanimate object that does not possess the characteristics of a living thing. Living things are typically characterized by the ability to grow, reproduce, respond to stimuli, and maintain homeostasis, none of which apply to a bag. Therefore, the correct answer is false.

Explanation
The correct answer includes the items "Rock," "Sun," and "Mobile phone." These items are non-living things because they do not possess the characteristics of living organisms. Rocks are inanimate objects, the Sun is a celestial body, and a mobile phone is a man-made device.

Explanation
The correct answer is "Man-made" because books are created by humans using paper, ink, and other materials. They are not naturally occurring objects like rocks or trees. Books require human intervention in the form of writing, printing, and binding to exist.

Explanation
Water is considered a natural substance because it occurs naturally in the environment. It is found in lakes, rivers, oceans, and even in the atmosphere as water vapor. Water is formed through natural processes such as evaporation, condensation, and precipitation. Although humans can manipulate and treat water for various purposes, such as purifying it for drinking or using it for industrial processes, the fundamental properties and existence of water are not created by human intervention. Therefore, water is classified as a natural substance.
