The term that most accurately characterizes black bears is omnivores. This is because they eat a variety of foods, including plants (grass, roots, berries), insects, fish, and mammals.
The black bear is common to North America. Black bears eat many foods, mainly grass, roots, berries, and insects. However, fish and mammals—including those already dead—are also part of their diet. Some tend to wander near campsites and can develop a taste for human food and garbage. Given this information, which term most accurately characterizes black bears? (1 point)

By the time energy from producers reaches tertiary consumers, typically only about 0.1% of the original energy is left. This is due to the loss of energy at each trophic level, primarily through metabolic processes and heat. Therefore, the correct response is 0.1%.

Animals obtain their nitrogen from plants. Plants absorb nitrogen from the soil in the form of nitrates and nitrites, and then animals gain nitrogen by consuming these plants (herbivores) or other animals that have consumed plants (carnivores). Therefore, the correct response is plants.

The most accurate example of a food chain is grass → rabbit → snake → hawk. This sequence correctly represents the flow of energy from a producer (grass) through primary consumers (rabbit), secondary consumers (snake), to tertiary consumers (hawk).

The correct response is corn. Corn is a plant and can photosynthesize, which allows it to produce its own energy, making it a producer in the ecosystem.
