Is it true or false that consumer cannot survive without producers?

Answer 1

A producer could continue to produce without the presence or interaction of consumers. For example: Bees will continue to make honey as long as they can access what they need as consumers to then become producers of honey. A bear, as a consumer, will not die if he doesn't consume the honey, as long as the bear can access other food sources as a consumer. But if a consumer must rely on one type of producer, and that producer fails to produce, the consumer would either need to find other sources of nutrients to consume, or if unable to find/adapt to other sources, the consumer would die.

Answer 2

No. Producers, i.e. organisms which photosynthesise, are the only way that energy can enter a food chain, the only way that food can start out. There's an old saying: 'All flesh is grass', which means that producers are at the bottom of every food chain. If there were no producers, there would be no food.

'When you destroy a blade of grass,

You poison England at her roots:

Remember, no man's foot can pass

Where evermore no green life shoots'
