SC.912.L.17.9 -- Food Webs, Energy Pyramids, and Energy Flow

Front

What is a producer in a food chain?

Back

A producer is an organism that makes its own food using light or chemicals, such as plants.

Front

What is the role of producers in an ecosystem?

Back

Producers form the base of the food chain and provide energy for consumers.

Front

What is an autotroph?

Back

An autotroph is an organism that produces its own food, typically through photosynthesis or chemosynthesis.

Front

What happens if a food chain or food web becomes unbalanced?

Back

An unbalanced food chain or web can lead to negative impacts on the ecosystem, such as species extinction or overpopulation.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both organisms benefit from the interaction.

Front

Can you give an example of mutualism?

Back

An example of mutualism is the relationship between hummingbirds and flowers, where hummingbirds feed on nectar and help pollinate the flowers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level.

Front

What are trophic levels?

Back

Trophic levels are the different levels in a food chain or food web, including producers, primary consumers, secondary consumers, and tertiary consumers.

Front

What is the significance of energy flow in an ecosystem?

Back

Energy flow is crucial for maintaining the balance of ecosystems, as it determines the availability of energy for organisms at different trophic levels.
