They would decompose quickly

They would pile up

They would turn into energy

They would disappear

A food web consists of only one linear path, while a food chain involves multiple paths.

A food web shows complex interconnections between organisms, while a food chain shows simple, direct feeding relationships.

A food chain is used only in marine ecosystems, while a food web is used in terrestrial ecosystems.

There is no difference; both models are used interchangeably.

The food web remains unchanged.

The balance of the food web is thrown off.

Only one organism is affected.

All organisms are destroyed.

It is returned to the plant population

It is used to convert CO₂ into sugars

It is lost to the environment as heat

It transforms into X-ray radiation

It is directly tied to the available energy

It is lost to the environment as heat

The matter is converted into energy

It is converted into glucose and oxygen

It is fully transferred to the next organism

It is used for growth and movement

It is stored indefinitely

It is lost completely
