1.

Which is the food factory of a plant?

Answer: Leaf
Explanation:
The leaf is considered the food factory of a plant because it contains specialized cells called chloroplasts that are responsible for photosynthesis. During photosynthesis, the chloroplasts use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen. The glucose is then used by the plant as a source of energy for growth and development. 
2.

What organ helps a mammal with breathing?

Answer: Lungs
Explanation:
Lungs help mammals to breathe by taking in oxygen from the air and removing carbon dioxide from the body. They are the main respiratory organs in mammals and are responsible for the exchange of gases between the body and the environment.
3.

Fish breathe through

Answer: Gills
Explanation:
Fish have gills, which are specialized organs that allow them to extract oxygen from water. Gills are located on the sides of the fish's head and are made up of thin, feathery filaments. As water passes over these filaments, oxygen is extracted and absorbed into the fish's bloodstream, while carbon dioxide is released back into the water. This adaptation enables fish to respire efficiently in their aquatic environment. Unlike lungs, which are found in terrestrial animals, fish rely solely on their gills for respiration. 
4.

Humans can't breathe__________.

Answer: Underwater
Explanation:
Humans cannot breathe underwater without the aid of special equipment like scuba gear or a submarine. Unlike fish, humans do not have gills to extract oxygen from water. Therefore, being submerged in water for an extended period of time without proper breathing apparatus would result in suffocation.
5.

Which organism is the largest land animal?

Answer: Elephant
Explanation:
The largest land animal is the elephant. Elephants are known for their massive size and can weigh up to several tons. They have a long trunk, large ears, and tusks. They are herbivores and are found in various habitats, including forests, savannahs, and grasslands. Elephants play a vital role in maintaining the ecosystem by creating water holes and clearing pathways in forests. They are highly intelligent and social creatures, living in herds and displaying complex social behaviors. Due to habitat loss and poaching, elephants are currently endangered, making their conservation a significant concern.
6.

We get light from

Answer: The Sun
Explanation:
The Sun is the correct answer because it is the primary source of light in our solar system. It emits light and heat through a process called nuclear fusion, where hydrogen atoms combine to form helium and release energy in the form of light. The moon reflects sunlight, but it does not produce its own light. The oceans and asteroids do not emit light either. 
7.

What do plants need to grow?

Answer: Water
Explanation:
Plants need water to grow because it helps them make their food through a process called photosynthesis. Water is absorbed by the plant's roots from the soil. The water travels up through the plant to the leaves, where it is combined with carbon dioxide and sunlight to create food (sugars) that the plant uses to grow. Without water, a plant cannot perform photosynthesis and will not be able to survive.
8.

What do we breathe in to stay alive?

Answer: Oxygen
Explanation:
We breathe in oxygen because our bodies need it to produce energy through a process called respiration. When we breathe, oxygen from the air enters our lungs and is transferred to our blood. The blood then carries the oxygen to all the cells in our body. In the cells, oxygen is used to convert the food we eat into energy. This energy is necessary for all our bodily functions, from moving and thinking to growing and repairing tissues. Without oxygen, our cells would not be able to produce energy, and we would not be able to survive.
9.

Where does the sun go at night?

Answer: The Earth rotates
Explanation:
The sun does not actually move or go anywhere at night. Instead, the Earth rotates on its axis. This means the Earth spins around like a top. As the Earth rotates, different parts of the world move into and out of the sun’s light. When it is daytime where we live, our part of the Earth is facing the sun and receiving sunlight. When it is nighttime, our part of the Earth has rotated away from the sun and is in shadow. This rotation of the Earth is why we experience day and night.
10.

What season comes after winter?

Answer: Spring
Explanation:
Spring comes after winter in the cycle of the four seasons. Winter is the cold season, and spring follows it, bringing warmer weather. During spring, the days get longer, temperatures rise, and many plants start to grow and bloom. Animals also become more active. Spring is often associated with renewal and new beginnings as the natural world awakens from the dormancy of winter. This seasonal cycle continues with summer following spring, bringing the warmest weather of the year.
