What is the difference between a food chain and a food web?

• In a food web, organisms are linked in a linear sequence, unlike a food chain.

• In a food chain, organisms are linked in a linear sequence of who eats whom, while a food web shows multiple interconnected food chains in an ecosystem.

• A food chain involves only producers and consumers, while a food web includes decomposers as well.

• A food chain is more complex than a food web.

Explain the concept of refraction of light.

• Refraction of light is the splitting of light into different colors

• Refraction of light is the bending of light as it passes from one medium to another due to a change in its speed.

• Refraction of light is the reflection of light off a surface

• Refraction of light is the absorption of light by a medium

What are the different types of motion? Provide examples for each.

• Spiral motion

• Linear motion, circular motion, periodic motion, rotational motion

• Irregular motion

• Rectangular motion

Describe the steps involved in the textile production process.

• Building houses, designing websites, performing surgery

• Cultivating or sourcing raw materials, spinning fibers into yarn, weaving or knitting yarn into fabric, dyeing and printing fabric, cutting and sewing fabric into garments, quality control and finishing processes.

• Baking bread, painting walls, repairing cars

• Harvesting crops, refining oil, assembling electronics

How does air pressure affect weather patterns?

• Air pressure only affects the temperature of the air

• Air pressure causes earthquakes

• Air pressure influences the movement of air masses, with high pressure systems bringing fair weather and low pressure systems bringing stormy weather.

• Air pressure has no impact on weather patterns

How do plants obtain energy in a food chain?

• Respiration

• Chemosynthesis

• Photosynthesis

• Fermentation

How does light interact with different objects based on their properties?

• Light can be absorbed and reflected by different objects based on their properties.

• Light can be refracted and transmitted by different objects based on their properties.

• Light can be absorbed, refracted, and transmitted by different objects based on their properties.

• Light can be reflected, absorbed, transmitted, or refracted by different objects based on their properties.

Discuss the relationship between speed and velocity in motion.

• Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. Speed is the magnitude of velocity. In motion, speed and velocity are related in that velocity gives the speed of an object along with its direction of motion.

• Speed and velocity are interchangeable terms in motion.

• Speed is a vector quantity that includes both speed and direction.

• Velocity is the magnitude of speed.

What are the key stages in fabric production from fibers?

• Spinning, weaving or knitting, dyeing, finishing

• Carding, crocheting, bleaching

• Spinning, sewing, printing

• Felting, stitching, ironing

Explain the impact of air pressure on flight.

• Air pressure determines the type of in-flight snacks served.

• Air pressure affects the lift force generated by the wings, impacting the aircraft's ability to stay airborne.

• Air pressure affects the pilot's choice of music during the flight.

• Air pressure impacts the color of the aircraft's paint job.
