Ecosystem and Energy Transfer Quiz

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

• A food chain shows a single linear path of energy transfer, while a food web shows interconnected food chains.

• A food chain shows interconnected food chains, while a food web shows a single linear path of energy transfer.

• A food chain represents the flow of energy from the eater to the eaten, while a food web represents the flow of energy from the eaten to the eater.

• A food chain and a food web are identical in structure and function.

In the example food chain provided (Grass → Grasshopper → Frog → Hawk), which organism is the producer?

• Grasshopper

• Frog

• Grass

• Hawk

Which term describes an organism that breaks down dead organic matter, such as fungi and bacteria?

• Producer

• Consumer

• Decomposer

• Omnivore

What does an energy pyramid illustrate about energy transfer in an ecosystem?

• Energy increases as it moves up trophic levels.

• Energy decreases as it moves up trophic levels.

• Energy remains constant across all trophic levels.

• Energy is only transferred at the producer level.

Which type of organism eats both plants and meat?

• Herbivore

• Carnivore

• Omnivore

• Decomposer

What is the 10% Rule in energy transfer within an ecosystem?

• 10% of energy is passed to the next level, while 90% is lost as heat or used for metabolism.

• 90% of energy is passed to the next level, while 10% is lost as heat or used for metabolism.

• Energy is equally distributed among all levels.

• Producers receive 90% of the energy, while consumers receive 10%.

Which type of symbiotic relationship benefits both species involved?

• Mutualism

• Commensalism

• Parasitism

• Predation

Which ecosystem has the highest biodiversity?

• Tropical Rainforests and Coral Reefs

• Deserts and Tundra

• Grasslands and Savannas

• Arctic and Alpine regions

What is the importance of higher biodiversity in an ecosystem?

• It leads to a more stable and resilient ecosystem.

• It reduces the number of species in the ecosystem.

• It increases the energy transfer efficiency.

• It prevents the growth of producers.

Which symbiotic relationship involves one species benefiting while the other is harmed?

• Parasitism

• Mutualism

• Commensalism

• Cooperation
