Question

A black bear that eats berries and fish would be classified as
A. A producer
B. An omnivore
C. A carnivore
D. An herbivore
E. An autotroph

Answer 1

Hint:An ecosystem can be seen as a functional unit of nature, in which living organisms will interact with each other and they also interact with the surrounding nature. The ecosystem varies greatly in terms of size from a small pond to a large forest. Ecologists say that the entire biosphere as a global ecosystem. This ecosystem is very large so it has to be studied one at a time. It can be divided into two categories one being terrestrial and the other being aquatic.

Complete answer:Producer- Producers are organisms that create food from inorganic matter. The producer's example being the plants, algae, and lichens which convert carbon dioxide and sunlight to carbohydrates.
An omnivore- Omnivorous are animals that can eat both animals and plants for their survival. They obtain energy and nutrients from plants and animal matters, they digest carbohydrates, fats, protein, fiber, and then they metabolize the nutrients and energy of the sources. Monkeys, bears, etc.
A carnivore- These are animals that get food from eating and killing other animals. Carnivores eat herbivores, omnivores, and occasionally other carnivores. These are very important to our ecosystem because they keep the other species from becoming overpopulated. An example is a lion, tiger, etc.
An herbivore- These are animals that are adapted to eat only plant materials like foliage or algae, for their diet. Examples are horses, deer, etc.
An autotroph- These are organisms that produce their food using light, carbon dioxide, water, or other chemicals. Because they produce their food they are sometimes called producers.
Hence the answer is option B, an omnivore.

Note: So to summarise the above points. Producers are green plants that convert solar energy into chemical energy. Omnivorous are tertiary consumers that prey on herbivores, carnivores, and producers for their food. Carnivores are the secondary consumers that prey on herbivores and producers. Herbivores are primary consumers that eat producers. Autotrophs prepare their food. So the bear eats berries and fishes which come under omnivorous animals.
