First of all, there's not such thing as "primary producer" it's called producer, but if that happens the primary consumer would die so the secondary consumer who is the one who eats the primary, would eat another animal or die.
the secondary consumer will have no easy source of food or may die
every thing would die
The consumers will die unless they find a new producer
The rest of the food chain would collapse and there would be lots of deaths from starvation.
The thing that gets eaten by the producer will just increase because no one eats them
If algae is the producer in a food chain of the ocean then corn would be a producer in a food chain on land. Any green plant is a producer.
No food will be produced. So no energy will be produced
The consumers will die unless they find a new producer
there would be no food for the consumers as a result there will be n life in the earth
you would die
diarrhea
The rest of the food chain would collapse and there would be lots of deaths from starvation.
the whole food chain would be destroyed
The ecosystem would not be successful. Eg, plants are eaten by deer. If the plants were removed, the deer would have to look for another food or die.
he would die cause whithout food the animal gonna die
Potentially bad stuff.
Other animals will die
If the produce is removed then the food chain will cease to exist. The consumers will then have nothing to eat and so will die.
since the grass is the crickets food the population of crickets would decrease if all the grass was removed
