The rabbits had eaten them all, and they could not reproduce as fast or faster than the rabbits could eat them.

The disease from the rabbits spread to the green plants and infected them, so they slowly died off.

Australia is very hot, and many plants cannot survive in those conditions, so they withered and died.

The farmer removed the green plants so that there was room for his rabbits to run free and jump.

Energy is recycled in a food chain and flows between producers, consumers, and decomposers.

Energy is accumulated at the top of the chain, and the final consumer gets all of it.

Energy starts with consumers and is passed to others through family groups and friendships.

Energy begins with plants and is passed to decomposers; from there, it moves to consumers and ends with the Sun and water.

The decomposers cannot keep up with the number of dead rabbits.

The decomposers could catch the same disease from eating sick rabbits.

All of the answer choices are correct.

The disease could mutate and spread to other animals in the ecosystem.

None of the answer choices are correct.

They eat all of the dead organisms and waste and return the energy to the Earth.

They clean up the dead animals, so people think Australia looks better.

They get the waste out of the way, so there is more room for rabbits.

None of the answer choices are correct.

All of the answer choices are correct.

The Sun provides energy for producers who transfer that energy when eaten, the trend continues through the chain.

The Sun provides energy for decomposers who transfer that energy when eaten, the trend continues through the chain.

The Sun provides energy for consumers who transfer that energy when eaten, the trend continues through the chain.

Energy is not transferred or transformed as it flows through a food chain.

All of the answer choices are correct.

The mushrooms represent the decomposer that breaks down waste from animal and plant remains.

The mushrooms represent the consumer that absorbs energy from eating other living things.

The mushrooms represent the producer that creates food from water, sunlight, and carbon dioxide.

None of the answer choices are correct.

Sun, producer, herbivore, carnivore, and decomposer

Producer, Sun, carnivore, herbivore, and decomposer

Sun, producer, predator, consumer, and decomposer

Herbivore, carnivore, Sun, producer, and decomposer

The mushrooms are decomposers and break down consumers and producers. They receive energy from all parts of the food chain.

The mushrooms are producers and break down consumers and producers. They receive energy from all parts of the food chain.

The mushrooms are consumers and break down decomposers and producers. They receive energy from all parts of the food chain.

The mushrooms are carnivores and break down herbivores and omnivores. They receive energy from all parts of the food chain.
