Predators are often another organism's prey, and likewise prey are often predators. Though blue jays prey on insects, they may in turn be prey for cats and snakes, and snakes may be the prey of hawks. One way of classifying predators is by trophic level. Organisms that feed on autotrophs, the producers of the trophic pyramid, are known as herbivores or primary consumers; those that feed on heterotrophs such as animals are known as secondary consumers. Secondary consumers are a type of carnivore, but there are also tertiary consumers eating these carnivores, quartary consumers eating them, and so forth. Because only a fraction of energy is passed on to the next level, this hierarchy of predation must end somewhere, and very seldom goes higher than five or six levels, and may go only as high as three trophic levels (for example, a lion that preys upon large herbivores such as wildebeest, which in turn eat grasses). A predator at the top of any food chain (that is, one that is preyed upon by no organism) is called an apex predator; examples include the orca, sperm whale, anaconda, Komodo dragon, tiger, lion, tiger shark, Nile crocodile, and most eagles and owls—and even omnivorous humans and grizzly bears. An apex predator in one environment may not retain this position as a top predator if introduced to another habitat, such as a dog among alligators, a skunk in the presence of the great horned owl immune to skunk spray, or a snapping turtle among jaguars; a predatory species introduced into an area where it faces no predators, such as a domestic cat or a dog in some insular environments, can become an apex predator by default.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What makes an organism a secondary consumer?
Ah, so.. feed on heterotrophs

Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened. Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own".[N 22] The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Mabel and Bell mobilized the community to help victims in Halifax.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did the Bells live when the Halifax Explosion happened?
Ah, so.. Beinn Bhreagh

As a schoolboy, Gaddafi adopted the ideologies of Arab nationalism and Arab socialism, influenced in particular by Nasserism, the thought of Egyptian revolutionary and president Gamal Abdel Nasser, whom Gaddafi adopted as his hero. During the early 1970s, Gaddafi formulated his own particular approach to Arab nationalism and socialism, known as Third International Theory, which has been described as a combination of "utopian socialism, Arab nationalism, and the Third World revolutionary theory that was in vogue at the time". He laid out the principles of this Theory in the three volumes of The Green Book, in which he sought to "explain the structure of the ideal society." His Arab nationalist views led him to believe that there needed to be unity across the Arab world, combining the Arab nation under a single nation-state. He described his approach to economics as "Islamic socialism", although biographers Blundy and Lycett noted that Gaddafi's socialism had a "curiously Marxist undertone", with political scientist Sami Hajjar arguing that Gaddafi's model of socialism offered a simplification of Karl Marx and Friedrich Engels' theories. Gaddafi saw his socialist Jamahiriyah as a model for the Arab, Islamic, and non-aligned worlds to follow.
