In an ecosystem, the plants are producers, herbivores are primary consumers (as they feed on the plants), carnivores are the secondary consumers (as they consume primary consumers) and higher carnivores or omnivores are the tertiary consumers. If any single component of the food chain is disturbed the rest are also disturbed.

For example, wolves can be thought of as secondary consumers in a grassland that also contains deer. If wolves are removed, the deer population will increase unchecked since their natural predator has been removed from the ecosystem. This will overburden the grasslands since the primary consumers are increasing in numbers. Over time, the deer population will start reducing due to the lack of food. Similarly, tertiary consumers (such as lions, etc.) may also be experience shortage of food since the secondary consumers are no longer available.

Thus, if we remove several secondary consumers from the ecosystem, the primary consumers, the producers, and the tertiary consumers are all affected.

Hope this helps.
