The food chain in the tundra consists of carnivores, herbivores and insects. Carnivores, because they are meat eaters, are at the top of the tundra food chain. Insects are at the bottom of the food chain, and herbivores fall in the middle of the chain.Continue Reading
At the top of the food chain in the tundra are polar bears. Not only do they eat meat, but they eat other carnivores, such as seals. Other carnivores in this cold region include wolves, foxes, grizzly bears, owls and migratory birds during certain types of the year. These animals seek out rich, fatty meats to eat so that they can gain enough weight to survive cold, harsh tundra winters.
Herbivores are below carnivores on the food chain. Caribou, arctic hares, lemmings and voles are all plant eaters that live in the tundra. Their strong sense of smell allows them to find vegetation to consume even in deep snow and ice. These herbivores become meals for the larger carnivores.
At the bottom of the food chain are arctic insects. Mosquitoes, bees, moths, grasshoppers and black flies survive in the tundra in the summer months. Many birds feed on insects during warmer times, when the bugs are plentiful. When the weather turns cold again, insects either migrate or die off.Learn more about Biology
The food chain in the Arctic tundra consists of many different large and small animals, plants and insects. Predators like wolves, owls, foxes and polar bears occupy the top of the food chain in the Arctic tundra. These predators prey on plant eaters and herbivores such as hares, caribou and lemmings who belong to the middle of the food chain.Full Answer >
A heterotroph is any organism, including carnivores, omnivores and herbivores, that cannot produce its own food through solar energy and must feed off another life form. In the food chain, heterotrophs represent the consumers. The autotrophs, such as plants and algae, are called the producers of the food chain because of their ability to produce their food with no need to consume another organism.Full Answer >
Mollusks are classified as herbivores, omnivores and carnivores, and their diets depend largely on the species and availability of food in a particular location. Some mollusks consume only algae and ocean plant matter, while others may eat shellfish and even small fish.Full Answer >
Producers (plants) in the savanna food chain are mainly grasses and shrubs. The primary consumers (herbivores) include giraffes, zebras, elephants, gazelles, wildebeests and warthogs. The carnivores are leopards, lions and cheetahs, and the scavengers are vultures, termites and hyenas. The decomposers include mushrooms, insects and microorganisms.Full Answer >
