5th grade Science LEAP review

Front

What is the process of decay in an ecosystem?

Back

Decay is the process by which dead organic matter is broken down by decomposers, returning nutrients to the soil and making them available for plants.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers, such as bacteria and fungi, break down dead organisms and waste, recycling nutrients back into the ecosystem.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

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 relationships.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and collection.

Front

What is the main source of energy for the Earth?

Back

The Sun is the main source of energy for the Earth, driving processes like photosynthesis and the water cycle.

Front

What is a sundial and how does it work?

Back

A sundial is a device that tells time by using the position of the Sun's shadow cast by a gnomon (a rod) on a marked surface.

Front

What is the importance of plants in preventing landslides?

Back

Plants help stabilize soil with their roots, reducing erosion and preventing landslides on slopes.

Front

What is the impact of heavy rainfall on soil stability?

Back

Heavy rainfall can saturate soil, making it loose and more prone to landslides.

Front

What is the role of animals in soil aeration?

Back

Burrowing animals create tunnels in the soil, which helps aerate it and can make it more susceptible to erosion.
