Answer 1

If primary consumers disappear from an ecosystem, the most likely response is:

The producer population increases, while the secondary consumer population decreases.

Without primary consumers to eat the producers (plants), the producers would thrive and increase in number. However, secondary consumers that rely on primary consumers for food would likely face a decrease in their population due to lack of available food sources.
