Primary consumers.
Secondary consumers.
Primary producers.
Tertiary consumers.
Detailed Explanation
In an ecological food chain, primary producers are those that photosynthesize and utilize sunlight as their energy source; this trophic level is almost entirely made up of plants. Primary consumers attain their energy from primary producers; cows are primary consumers as they survive solely on grass. Secondary consumers, such as wolves and eagles, feed upon primary consumers, and tertiary consumers, like great white sharks, feed upon primary and secondary consumers.
