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, illustrating feeding relationships.

Front

What is the correct order of a food chain in a grassland ecosystem?

Back

Grasses → beetles → songbirds → foxes.

Front

What is the purpose of conducting an experiment?

Back

To test a hypothesis by observing and measuring the effects of changing one or more variables.

Front

What should students do to determine the force needed to drag a block across different surfaces?

Back

Measure the force required to drag the same block over four different surfaces and conduct three trials for each surface.

Front

How can you identify if a block is made of iron?

Back

Place a magnet close to each of the blocks; iron is magnetic.

Front

What types of energy are involved in making a toy car move?

Back

Light, electrical, and mechanical energy.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding.

Front

What is the role of producers in a food chain?

Back

Producers, like plants, create their own food through photosynthesis and provide energy for consumers.

Front

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

Back

A food chain shows a single pathway of energy flow, while a food web shows multiple interconnected pathways.

Front

What is the scientific method?

Back

A systematic process for experimentation that includes observation, hypothesis formulation, experimentation, and conclusion.
