The sequence in which energy and nutrients are transferred from one organism to the next is known as (A) a habitat. (B) a food chain. (C) a community. (D) an ecosystem.

The correct answer is (B) a food chain.<br /><br />A food chain is the sequence in which energy and nutrients are transferred from one organism to the next. It represents the flow of energy and matter through an ecosystem, where each organism occupies a specific trophic level and feeds on the organism below it. The sequence starts with producers, such as plants, which convert sunlight into energy through photosynthesis. Consumers, such as herbivores, then feed on the producers, and predators feed on the consumers. This transfer of energy and nutrients is essential for the functioning of ecosystems and the survival of organisms.
