Understanding Food Chains

What is a habitat?

• A type of food chain

• A place where organisms can find food, water, and shelter

• A specific type of plant

• A group of decomposers

Which of the following is NOT a producer?

• Fungi

• Cyanobacteria

• Plants

• Algae

What do herbivores primarily consume?

• Both plants and animals

• Plants

• Decomposers

• Other animals

Which type of consumer eats both plants and animals?

• Omnivores

• Carnivores

• Herbivores

• Decomposers

What role do decomposers play in the ecosystem?

• They produce food through photosynthesis

• They consume only plants

• They are at the top of the food chain

• They break down dead organisms and recycle nutrients

In a pond food chain, what is the role of algae?

• Consumer

• Decomposer

• Carnivore

• Producer

Which of the following is an example of a food chain in the tundra region?

• Grass -> Caterpillar -> Frog -> Snake -> Eagle

• Plants -> Rabbits -> Snakes -> Eagles

• Phytoplankton -> Krill -> Squids -> Emperor Penguins -> Killer Whales

• Algae -> Small Fish -> Larger Fish -> Swans

What is the ultimate source of energy for all food chains?

• Soil

• The Sun

• Water

• Decomposers

How do decomposers contribute to the carbon cycle?

• By producing oxygen

• By releasing carbon dioxide into the air

• By creating new carbon compounds

• By consuming carbon dioxide

Which of the following is a correct sequence in a food chain?

• Decomposers -> Carnivores -> Herbivores -> Plants

• Plants -> Herbivores -> Carnivores -> Decomposers

• Carnivores -> Herbivores -> Plants -> Decomposers

• Herbivores -> Plants -> Carnivores -> Decomposers
