Ecosystem Quiz

What are the two main components that make up an ecosystem?

• Producers and consumers

• Biotic and abiotic components

• Food chains and food webs

• Decomposers and nutrient cycles

Which of the following is NOT an example of an abiotic component in an ecosystem?

• Soil

• Climate

• Water

• Bacteria

What is the primary difference between small-scale local ecosystems and biomes?

• Their components

• Their size and scale

• The types of organisms present

• The presence of nutrient cycling

Which process do producers use to convert energy from the environment into sugars?

• Decomposition

• Consumption

• Photosynthesis

• Respiration

How does a food web differ from a food chain?

• A food web only includes producers

• A food chain is more complex than a food web

• A food web shows multiple connections between organisms

• A food chain includes decomposers, while a food web does not

What is the primary role of decomposers in an ecosystem?

• To produce energy from sunlight

• To consume other organisms

• To break down organic matter and recycle nutrients

• To regulate the population of producers

In a pond ecosystem, which of the following would be considered a top predator?

• Algae

• Mayfly

• Dragonfly

• Heron

What is the importance of nutrient cycling in an ecosystem?

• It provides energy to producers

• It maintains the balance of the food web

• It controls the population of consumers

• It recycles nutrients back into the soil for future use

Which statement best describes the interrelationships in an ecosystem?

• Only biotic components interact with each other

• Abiotic components have no effect on living organisms

• There are many interactions between biotic and abiotic components

• Producers and consumers do not interact directly

Why is balance important in small ecosystems like ponds?

• It ensures that only one species dominates

• It prevents the ecosystem from growing larger

• Changes in one part can impact other components of the food chain

• It eliminates the need for decomposers
