What comes first in order plants snail sea gull crab based on which energy moves between in a food chain?

In a food chain, energy typically flows from producers to consumers. In this case, plants are the primary producers, as they convert sunlight into energy through photosynthesis. Next, snails can be considered primary consumers that eat plants. Following that, crabs can be secondary consumers that may eat snails, and sea gulls, as tertiary consumers, may prey on crabs. Thus, the order is: plants → snails → crabs → sea gulls.
