What is the name given to the complex prey/predator cycle in which all animals (including man) take part?

1. Food Chain

2. Habitat

3. Ecosystem

4. Food Web

The correct answer is: Food Chain

The correct answer is the food chain, as it outlines how energy and nutrients flow between different organisms in a linear sequence, representing one aspect of the broader ecological interactions that define the relationships between predator and prey. In a food chain, various trophic levels illustrate how species are interconnected through these feeding relationships, starting from primary producers, like plants, up to primary consumers (herbivores), and then secondary and tertiary consumers (carnivores). Each organism plays a role and depends on others for survival, making it essential to understand these dynamics when studying ecological systems. While the food web is a more complex and realistic representation of the feeding relationships in an ecosystem, the question specifically calls for a single cycle of interactions, which is best illustrated by the concept of a food chain. Other options may represent environments or the broad interactions of organisms and their surroundings, but they do not specifically focus on the predator/prey relationships in the manner that a food chain does.
