Because people hurt third level consumers
yes black bears are omnivores they are third level consumers they eat fish berries and more!
trophic level one.... the tertiary consumers, or top carnivores
why are there relatively few third-level consumers in an ecosystem?why are there fewer 3rd level consumers in an ecosystem?
The second level consumers would have nothing to feed off, and therefore would commence eating themselves. Eventually the ecosystem would die out.
A first level consumer is one that consumes producers (plants) directly. First level consumers in the tundra biome would include small herbivores such as lemmings and rabbits, and large grazers such as elk.
Polar bears are tertiary (3rd level) consumers.
Most ecosystems ultimately rely on sunlight as the source of energy. Sunlight is used by plants to manufacture food. Plants are eaten by herbivores, and herbivores are in turn eaten by top-level consumers like hawks. Therefore hawks ultimately depend on sunlight for their food. At the bottom of the sea, near thermal vents, scientists have discovered new ecosystems that do not rely on sunlight, but on the chemicals and heat present at those vents as a source of energy for bacteria, which are eaten by larger organisms. The top level consumers in those ecosystems do not depend on sunlight for their food.

Secondary, tertiary and fifth level consumers, or Apex consumers are the primary residents in the Tundra biome. This includes Arctic foxes, polar bears, caribou, and the snowy owl.
What level consumer is a jaguar
First level consumers ?
they are second level consumers
