• To break down dead plants and animals

• To recycle nutrients back into the soil

Which of the following is an example of a decomposer?

• Herbivore

• Carnivore

• Fungi

• Omnivore

What abiotic factor is most likely to limit the survival of organisms in a desert ecosystem?

• High temperature

• Limited water

• Abundant sunlight

• Rich soil nutrients

How do human activities negatively impact ecosystems?

• By promoting conservation efforts

• By practicing sustainable methods

• By causing pollution and deforestation

• By studying ecosystems

Why is it important to study ecosystems?

• To understand how living and non-living components interact

• To increase pollution

• To harm biodiversity

• To reduce the survival of species

What is an ecosystem?

• A community of living organisms interacting with their non-living environment

• A group of producers creating their own food

• A collection of abiotic factors

• A system of decomposers recycling nutrients

Which process do producers use to create their own food?

• Photosynthesis

• Respiration

• Decomposition

• Fermentation

What do decomposers do in an ecosystem?

• Break down dead plants and animals

• Consume both plants and animals

• Transfer energy through the food chain

• Create their own food

Which of the following is an abiotic factor?

• Sunlight

• Plants

• Animals

• Decomposers

What is the primary energy source for other organisms in an ecosystem?

• Energy-rich sugars produced by plants

• Nutrients recycled by decomposers

• Water

• Sunlight
