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.Know More
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
Elephants, rhinos, moose, squirrels and giraffes are all herbivores.Herbivores are the second level of the food chain and are the primary consumers, or first consumers, on the food chain.Full Answer >
Mountain gorillas are large, powerful herbivores with no predators above them in the food chain; they feed on everything from wild grass to tree pulp and once they reach their adult size after several years of growth they have no natural predators in their home range. Mountain gorillas are important to their local ecologies because they help keep plant growth under control by grazing on stems, shoots and leaves which also gives trees opportunities to put out new growth.Full Answer >
According to the CK-12 Foundation, protists are helpful to humans because they produce oxygen, are used in medical research, are an important part of the food chain and are even used in food. In fact, protists help to recycle the nutrients necessary for plant and animal life.Full Answer >
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
