The correct response is "decrease."
In a food chain, energy transfer between organisms is generally inefficient, with typically only about 10% of the energy being transferred from one trophic level to the next. This means that, as you move up the food chain, the amount of energy available decreases.

The correct response is "three to five organisms."
Most food chains typically consist of three to five trophic levels, as energy transfer between levels is inefficient, limiting the number of levels that can be sustained.

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)

The correct response is "omnivores."
Black bears have a varied diet that includes plants (grass, roots, berries) and animal matter (insects, fish, and other mammals), which classifies them as omnivores.

The correct response is "a decomposer, a producer, and some consumers."
A typical food chain consists of a producer (such as a plant), one or more consumers (herbivores and/or carnivores), and often includes decomposers that break down dead organic matter.
