Eco Quiz

What is the role of producers in a food chain?

• They decompose dead organisms.

• They consume other organisms for energy.

• They produce energy-rich compounds that are used by other organisms.

• They regulate the population of other species.

Which of the following is an example of a consumer?

• Grass

• Sun

• Wolf

• Mushroom

What is the primary role of decomposers in an ecosystem?

• To produce oxygen through photosynthesis.

• To consume living plants and animals.

• To break down dead organisms and recycle nutrients back into the ecosystem.

• To regulate the climate by absorbing carbon dioxide.

How does energy flow in a food chain?

• From decomposers to producers to consumers.

• From consumers to producers to decomposers.

• From producers to consumers to decomposers.

• Energy does not flow; it remains constant in each organism.

What is the process of decomposition?

• The conversion of inorganic compounds into organic compounds by producers.

• The process by which consumers obtain energy from eating other organisms.

• The breakdown of dead matter and waste into simpler substances by decomposers.

• The production of energy by the sun.

Which organism is most likely to be a producer?

• A lion

• A mushroom

• A tree

• A fish

What adaptation might a consumer have to help it obtain food?

• Chlorophyll to perform photosynthesis

• Sharp teeth to tear meat

• Roots to absorb water and nutrients from the soil

• Spores to reproduce

Why are fungi considered decomposers?

• They produce their own food through photosynthesis.

• They consume live plants and animals.

• They break down dead organic material, returning nutrients to the soil.

• They regulate the temperature of their environment.

What characteristic is common to all producers?

• They all have roots.

• They all consume other organisms for energy.

• They all use sunlight to produce food through photosynthesis.

• They all have the ability to move from one place to another.

Which of the following best describes the energy flow in an ecosystem?

• Linear, from the sun to producers to consumers to decomposers.

• Circular, with energy returning to the sun after it passes through decomposers.

• Random, with no predictable pattern of energy flow.

• Static, with energy levels remaining constant across all organisms.
