What is photosynthesis, and why is it important for plants?
Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce their food in the form of glucose. This process also releases oxygen, which is essential for life on Earth.

Define the term 'ecosystem' with an example.
An ecosystem is a community of living organisms interacting with their physical environment. For example, a forest ecosystem includes trees, animals, birds, and microorganisms living together with soil, air, and water.

What are the different types of nutrition found in living organisms?
The two main types of nutrition are autotrophic nutrition, where organisms make their own food (e.g., plants), and heterotrophic nutrition, where organisms depend on others for food (e.g., humans and animals).

How do plants absorb water from the soil?
Plants absorb water from the soil through root hairs by the process of osmosis. The water then moves upward through the xylem vessels to different parts of the plant.

What is the function of stomata in plants?
Stomata are tiny pores on the surface of leaves that help in gas exchange and transpiration. They allow carbon dioxide to enter for photosynthesis and release oxygen and excess water vapor.

Differentiate between unicellular and multicellular organisms.
Unicellular organisms have only one cell that performs all life functions, such as bacteria and amoeba. Multicellular organisms have multiple cells with specialized functions, like humans and plants.

What is the role of chlorophyll in photosynthesis?
Chlorophyll is the green pigment in plant cells that captures sunlight and converts it into chemical energy during photosynthesis.

Explain the function of the human digestive system.
The human digestive system helps in breaking down food into smaller molecules for absorption and energy production. It includes organs like the mouth, stomach, intestines, and liver.

How does the respiratory system work in humans?
The respiratory system allows the body to take in oxygen and remove carbon dioxide. The lungs play a major role in gas exchange, which happens in the alveoli.

Why is the heart called a double pump?
The heart is called a double pump because it has two circuits—one pumps oxygen-rich blood to the body, and the other pumps oxygen-poor blood to the lungs for oxygenation.

What is the importance of the skeletal system?
The skeletal system provides structure, support, and protection to the body. It also helps in movement and the production of blood cells in the bone marrow.

Define reproduction and its types.
Reproduction is the biological process by which organisms produce offspring. It is of two types: sexual reproduction (involving male and female gametes) and asexual reproduction (without gametes, like in bacteria).

What is the function of the nervous system?
The nervous system controls body functions and responses. It consists of the brain, spinal cord, and nerves that help in communication and coordination.

How do vaccines help in disease prevention?
Vaccines contain weakened or inactive forms of pathogens that stimulate the immune system to produce antibodies, protecting the body from future infections.

What are communicable and non-communicable diseases?
Communicable diseases spread from one person to another through air, water, or contact, like the flu. Non-communicable diseases do not spread and are caused by genetic or lifestyle factors, like diabetes.

How do insects help in pollination?
Insects like bees and butterflies transfer pollen from one flower to another while collecting nectar, helping in fertilization and seed production.

What is adaptation in animals?
Adaptation is the process by which animals develop special features to survive in their environment, like the thick fur of polar bears to withstand cold.

How does the water cycle work?
The water cycle involves evaporation, condensation, and precipitation. Water from oceans and rivers evaporates, forms clouds, and returns to the earth as rain.

Why is deforestation a major environmental issue?
Deforestation leads to loss of biodiversity, climate change, and soil erosion. It also reduces oxygen production and increases carbon dioxide in the atmosphere.

Explain the role of decomposers in nature.
Decomposers like bacteria and fungi break down dead plants and animals, recycling nutrients back into the soil for plants to use.

What is the greenhouse effect, and how does it impact the Earth?
The greenhouse effect occurs when gases like carbon dioxide trap heat in the atmosphere, leading to global warming and climate changes.

How do amphibians survive both on land and in water?
Amphibians like frogs have moist skin that helps in respiration in water and lungs for breathing on land.

What is the importance of biodiversity?
Biodiversity ensures a balanced ecosystem by supporting different species that contribute to food chains, climate stability, and ecological health.

Why do we see different seasons on Earth?
Seasons occur due to the tilt of the Earth's axis and its revolution around the Sun, leading to changes in temperature and climate.

How does soil erosion occur, and how can we prevent it?
Soil erosion occurs due to wind, water, and deforestation. It can be prevented by planting trees, using contour farming, and maintaining soil cover.

What are renewable and non-renewable resources?
Renewable resources, like solar and wind energy, can be replenished. Non-renewable resources, like coal and petroleum, take millions of years to form and are limited.

What is the function of red and white blood cells?
Red blood cells transport oxygen to body tissues, while white blood cells fight infections and help in immunity.

How do birds fly?
Birds fly using their lightweight bones, strong flight muscles, and aerodynamic wings that help them lift and glide through the air.

What is the importance of proteins in the human body?
Proteins help in body growth, repair, and the production of enzymes and hormones essential for metabolism.

How do fishes breathe underwater?
Fishes breathe using gills, which extract oxygen from water and release carbon dioxide.

Why is blood circulation important?
Blood circulation transports oxygen, nutrients, and hormones to different parts of the body while removing waste products.

What are food chains and food webs?
A food chain shows the flow of energy from producers to consumers. A food web is a complex network of interconnected food chains in an ecosystem.

How does pollution affect human health?
Pollution leads to respiratory diseases, skin problems, and waterborne illnesses. Air pollution can cause lung damage, while water pollution spreads infections.

What is the importance of forests?
Forests provide oxygen, maintain ecological balance, prevent soil erosion, and serve as habitats for wildlife.

Why is conservation of water important?
Water is essential for life, and its conservation ensures a steady supply for drinking, agriculture, and industry, preventing scarcity.

What is an endangered species?
An endangered species is one that is at risk of extinction due to habitat destruction, hunting, or environmental changes.

How do reptiles regulate their body temperature?
Reptiles are cold-blooded and depend on external heat sources like the sun to regulate their body temperature.

What is a balanced diet?
A balanced diet includes all essential nutrients like carbohydrates, proteins, fats, vitamins, and minerals needed for healthy growth and functioning.

Why do some animals hibernate?
Hibernation is a survival strategy where animals reduce their metabolism and sleep for long periods to conserve energy in cold weather.

How do earthworms help in farming?
Earthworms improve soil fertility by breaking down organic matter and increasing aeration, which helps in plant growth.

What is pasteurization, and why is it important?
Pasteurization is the process of heating liquids like milk to kill harmful bacteria, making them safe for consumption.

Why is regular exercise important for health?
Exercise strengthens muscles, improves heart health, boosts immunity, and helps maintain a healthy weight.

How do plants respond to stimuli?
Plants respond to stimuli like light, gravity, and touch through movements such as bending toward light (phototropism) and root growth downward (gravitropism).

Why do leaves appear green?
Leaves appear green because they contain chlorophyll, which absorbs all colors of light except green, which is reflected.
