Front

What is a food chain?

Back

A food chain is a sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, starting from producers (like plants) to consumers (like animals and humans).

Front

How do humans get energy from food?

Back

Humans get energy from food that comes from plants and animals, which ultimately derive their energy from the sun.

Front

Why does the Sun appear larger than other stars?

Back

The Sun appears larger than other stars because it is much closer to Earth than other stars, making it look bigger.

Front

What is the role of gravity in falling objects?

Back

Gravity is the force that pulls objects toward the Earth, causing them to fall when released.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the significance of the Sun in the food chain?

Back

The Sun provides energy that is essential for plants to grow, which are the primary producers in the food chain.

Front

What is an example of a producer in a food chain?

Back

An example of a producer is grass, which uses sunlight to create energy through photosynthesis.

Front

What is an example of a consumer in a food chain?

Back

An example of a consumer is a cow, which eats grass to obtain energy.

Front

What happens to energy as it moves up the food chain?

Back

As energy moves up the food chain, it decreases because some energy is lost as heat and through metabolic processes.

Front

What is the concept of perspective in observing objects?

Back

Perspective refers to how the position of an observer affects the appearance of objects, such as how closer objects look larger.
