What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow through different food chains.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients are transferred from one organism to another in an ecosystem, starting from producers to various levels of consumers.

Front

What role do producers play in a food chain?

Back

Producers, such as plants and algae, create their own food through photosynthesis and form the base of the food chain.

Front

What is the primary source of energy for most ecosystems?

Back

The sun is the primary source of energy for most ecosystems, providing the energy needed for photosynthesis.

Front

What is the difference between weathering and erosion?

Back

Weathering is the process of breaking down rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of sediment, which can include minerals, organic matter, and fragments of other rocks.

Front

What is learned behavior in animals?

Front

What is the role of the sun in the Earth's daily cycle?

Back

The sun appears to move across the sky due to the Earth's rotation on its axis, creating day and night.

Front

What is the significance of grass in a grassland ecosystem?

Back

Grass serves as a primary producer in grassland ecosystems, providing energy for herbivores and supporting the entire food chain.
