C. Short answer questions
1. Why do animals move from one place to another?
2. What would happen to a living thing if it did not get enough food?
3. Give an example of a plant responding to changes in its surroundings.
D. Long answer questions
1. Name the five sense organs. How do they help us?
2. What would happen if living things did not reproduce?
3. Imagine that you found something new and strange. How would you understand if it is a living thing or not?
Answer (2)
Animals move to find food, mates, and safe habitats. Without enough food, living organisms can suffer serious health issues and may not survive. Plants respond to their environment, like how sunflowers track the sun, and the five senses help us interact and understand the world around us.

C. Short answer questions:
Animals move from one place to another for several reasons. They may move to find food, water, and shelter, escape from predators, seek mates, or migrate to different habitats due to changes in the weather or seasons.
If a living thing did not get enough food, it would lack the necessary energy to perform essential functions. This can lead to weakness, poor health, and eventually, if the situation persists, it could result in illness or death.
An example of a plant responding to changes in its surroundings is a sunflower turning its head towards the sun to absorb more sunlight for photosynthesis, a process known as phototropism.
D. Long answer questions:
The five sense organs are the eyes, ears, nose, tongue, and skin. These organs help us interact with our environment:
Eyes : Allow us to see and detect light.
Ears : Enable us to hear and maintain balance.
Nose : Allows us to smell and detect scents, which is crucial for taste as well.
Tongue : Helps us taste different flavors and communicates texture information to the brain.
Skin : Detects touch, temperature, and pain, providing protection and sensory feedback.
If living things did not reproduce, they would eventually become extinct. Reproduction ensures the continuation of species by producing new individuals to replace those that die.
To determine if something you found is a living thing, observe its characteristics such as:
Growth : Does it grow or develop over time?
Reproduction : Can it reproduce or create offspring?
Response to Stimuli : Does it react to changes in its environment?
Metabolism : Does it take in nutrients and convert them to energy?
Cellular Structure : Is it composed of cells, the basic unit of life? By examining these characteristics, you can decide if the object is living or non-living.
