A keystone species is very important for keeping ecosystems functioning and in balance. For example, if a keystone species like the polar bear is removed from the Arctic habitat, seal populations will rise significantly, which also affects other organisms in the food chain such as the small fish and plankton.
Secondly, where is the black bear in the food chain? The Black Bear is what is called an apex predator, or rather, a predator that sits at the top of the food chain.
Beside this, is a polar bear a decomposer?
Animals like lions, tigers, cats, wolves, sharks, walruses, polar bears, seals, vultures, anteaters, and owls eat other animals to get energy. Another kind of consumer eats only dead plants and animals. These consumers are called decomposers.
What is a desert food chain?
A food chain is a way of showing how living organisms get their energy from each other. In the desert, producers like cacti, shrubs, and trees use sunlight to create their own food. Plant producers are then consumed by consumers like insects and mice, who are then eaten by larger animals.
