It is all living organisms, ranging from Autotrophic and and Heterotrophic; herbivore, carnivore and an omnivore. An example can be us as humans, as we eat and turn what we eat into energy. This also applies to plants and marine animals.
Many different animal species are placed at many different trophic levels. Insects for example tend to be on a low trophic level.
plants and algae
An eagle is an example of an animal that fills more than one trophic level. As a predator, it occupies a higher trophic level when it preys on smaller animals like rodents or fish. However, when it dies, it becomes food for scavengers like vultures or insects, placing it in a lower trophic level as a source of nutrients.
Yes, when their diet varies they can fill more than one trophic level
That's where an organism fits in the food chain. Like, a Hawk will eat a snake; a snake will eat a mouse; a mouse will eat a grasshopper; a grasshopper eats plants. The hawk is at the top of the trophic level pyramid in this example.
The first trophic leval
Scavengers are on every trophic level
In an ecosystem, energy decreases at each trophic level, typically following the 10% rule, where only about 10% of the energy is transferred from one level to the next. For example, if the primary producers (first trophic level) capture 1,000 calories of energy from sunlight, primary consumers (second trophic level) would receive around 100 calories, secondary consumers (third trophic level) about 10 calories, and tertiary consumers (fourth trophic level) only about 1 calorie. This energy loss is due to metabolic processes, heat, and inefficiencies in energy transfer.
trophic as in higher trophic levels feed on lower ones
Trophic essentially means to do with nutrition, but when applied (as it often is) to ecology, it refers to feeding habits, and the feeding relationship between different organisms. For example, trophic level means the nutrition or food level, and the position of an organism in the food chain.

Third trophic level. It eats insects.
