Olympiad Test Level 1: Living and Non Living Things - 2 - Class 2 MCQ

Living things will die without food. It is one of the basic necessity of life.

A bird is a living thing so it can move by flying. But it can glide also, a table is a non living thing and it can not move.

Ship is a man-made non-living thing.

The answer is C: Water

Here is a detailed explanation:

• A boy needs air: Oxygen is necessary for respiration, and without it, the boy cannot survive.


• A boy needs food: Food provides essential nutrients, vitamins, and minerals required for the proper functioning of the body.


• A boy needs water: Water is essential for hydration, maintaining body temperature, and supporting various physiological processes.


• A boy does not necessarily need toys: While toys can provide entertainment and stimulation, they are not essential for basic survival.


• A boy does not necessarily need clothes: While clothes provide protection and comfort, they are not essential for the fundamental requirements of staying alive.


• A boy does not necessarily need chocolate: Chocolate is a food item and can provide some nutritional value, but it is not a basic necessity for survival.

In conclusion, while air, food, and water are essential for a boy to stay alive, toys, clothes, and chocolate are not necessary for basic survival.

A car is a non living thing so it can not move but if we put petrol in it, it will move with the help of Petrol.

Explanation:
To provide a detailed solution, here is an explanation of why living things will die if they do not get air, water, and food:
Air:
- Air is essential for living things as it contains oxygen, which is required for cellular respiration.
- Cellular respiration is the process where cells use oxygen to produce energy in the form of ATP (adenosine triphosphate).
- Without oxygen, cells cannot produce energy, leading to the death of living organisms.
Water:
- Water is crucial for various biological functions, including hydration, transportation of nutrients, and removal of waste products.
- It helps regulate body temperature, lubricates joints, and maintains proper organ function.
- Without sufficient water, living organisms can become dehydrated, leading to organ failure and death.
Food:
- Food provides the necessary nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals, required for growth, development, and maintenance of the body.
- These nutrients are used for energy production, building and repairing tissues, and supporting various metabolic processes.
- Without an adequate supply of food, living organisms will experience malnutrition, weakness, and eventually, death.
All of these:
- Each of these factors, air, water, and food, is essential for the survival of living organisms.
- They are interconnected and work together to support life functions.
- If any of these elements are missing, the body cannot sustain itself, leading to the death of the organism.
In conclusion, living things will die if they do not get air, water, and food because these elements are vital for their survival and proper functioning.

Living Things in the Given Options:


A: The first option is an image of a non-living object, which appears to be a piece of machinery. It does not meet the criteria of a living thing as it does not exhibit characteristics such as growth, reproduction, or response to stimuli.


B: This option is an image of a plant. Plants are living things as they exhibit characteristics of life such as growth, reproduction, and response to stimuli. They also require energy, have cells, and undergo metabolic processes.


C: The third option is an image of a non-living object, which appears to be a piece of artwork or sculpture. It does not meet the criteria of a living thing as it lacks the necessary characteristics mentioned above.


D: The fourth option is an image of a non-living object, which appears to be a man-made structure or monument. Similar to the previous options, it does not exhibit the characteristics of a living thing.


Therefore, the correct answer is B: the image of the plant.

Answer:
The following options move from place to place:
A: Stone
- Stones do not have the ability to move from place to place on their own. They are stationary objects and cannot change their location without external force.
B: Leaf
- Leaves are typically attached to plants and trees. While they may move in the wind, they do not have the ability to actively move from place to place.
C: Dog
- Dogs are living beings and have the ability to move from place to place. They can walk, run, and explore different locations.
D: Chair
- Chairs are inanimate objects and do not have the ability to move from place to place on their own. They require human or external force to be moved.
Conclusion:
Based on the given options, the only item that can move from place to place is a dog (Option C). Dogs have the ability to walk and run, allowing them to change their location.

What does a plant need for healthy growth?
There are several key factors that contribute to the healthy growth of plants. These include:
1. Sunlight:
- Plants need sunlight to carry out photosynthesis, a process that converts sunlight into energy for growth.
- Sunlight provides plants with the necessary energy to produce food and nutrients.
2. Water:
- Water is essential for plant growth as it is involved in various physiological processes.
- It helps transport nutrients from the soil to different parts of the plant and maintains turgidity.
- The right amount of water is crucial for plant health; too little or too much can adversely affect growth.
3. Nutrients:
- Plants require a range of essential nutrients such as nitrogen, phosphorus, and potassium for healthy growth.
- These nutrients are obtained from the soil and are necessary for various plant functions, including cell division, photosynthesis, and root development.
4. Soil:
- The quality and composition of the soil play a significant role in plant growth.
- Good soil should provide proper drainage, sufficient aeration, and the necessary nutrients for plants to thrive.
5. Temperature:
- Different plants have specific temperature requirements for optimal growth.
- Extreme temperatures, either too hot or too cold, can hinder the growth and development of plants.
6. Air:
- Adequate air circulation is crucial for plant growth as it helps in the exchange of gases.
- Plants require carbon dioxide for photosynthesis and oxygen for respiration.
7. Space:
- Sufficient space is essential for plants to grow and spread their roots.
- Overcrowding can lead to competition for resources and hinder healthy growth.
Conclusion:
To ensure healthy plant growth, it is important to provide plants with the right amount of sunlight, water, nutrients, suitable soil conditions, appropriate temperature, proper air circulation, and sufficient space. By meeting these requirements, plants can thrive and reach their full potential.

Flower cannot move by itself some one carries it from one place to other.

A cat can move by itself but a table cannot.

The odd one out in this given set of options is "D: Truck". Here is the detailed explanation:
A: Truck
- A truck is a motor vehicle designed to transport cargo.
- It is usually larger in size than a car and has a separate cabin for the driver.
- Trucks are commonly used in transportation and logistics industries.
B: Wood
- Wood is a solid material that comes from trees.
- It is used for various purposes like construction, furniture, and fuel.
- Wood is composed of cellulose fibers embedded in a matrix of lignin.
C: Rock
- Rock is a naturally occurring solid aggregate of minerals or mineraloids.
- It is classified into three major types - igneous, sedimentary, and metamorphic rocks.
- Rocks are composed of different minerals and can be used for various purposes like building materials and jewelry.
D: Water
- Water is a liquid substance.
- It is essential for survival and is found in various forms like rivers, oceans, and lakes.
- Water is composed of molecules made up of two hydrogen atoms and one oxygen atom (H2O).

Explanation:
- Water, wood, and rock are all natural elements found in nature.
- They are all composed of different materials and have distinct properties.
- However, a truck is a man-made vehicle used for transportation and does not fit into the category of natural elements.
- Hence, "A: Truck" is the odd one out in this given set.

Cup is not natural but made by others.

Water is a natural thing.
