What is a biotic factor in an aquatic ecosystem?

Back

A biotic factor is a living component of an ecosystem, such as plants, animals, and microorganisms. In a tank, seaweed is an example of a biotic factor that fish interact with.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. In a circuit, materials like plastic are insulators, while metals are conductors.

Front

Which object cannot complete an electric circuit?

Back

A plastic comb cannot complete an electric circuit because it is an insulator and does not conduct electricity.

Front

How do you complete a circuit?

Back

To complete a circuit, you need to connect the components in a way that allows electricity to flow. For example, connecting points A to D in a circuit diagram can turn on a light.

Front

What is light refraction?

Back

Light refraction is the bending of light as it passes from one medium to another, such as from air into water. It causes objects to appear distorted or displaced.

Front

What are abiotic factors?

Back

Abiotic factors are non-living components of an ecosystem, such as water, rocks, and temperature. They influence the living organisms in the environment.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Metals like copper and aluminum are good conductors.

Front

What happens when a circuit is incomplete?

Back

When a circuit is incomplete, electricity cannot flow, and devices like light bulbs will not turn on.

Front

What is the role of batteries in a circuit?

Back

Batteries provide the electrical energy needed to power a circuit. They create a flow of electrons that allows devices to operate.
