Detailed explanation-1: -Mouse occupies the trophic level of secondary consumers, while owl is the tertiary consumer.

Detailed explanation-2: -Tertiary consumers are preyed on by quaternary consumers. These quaternary consumers are often the apex predators, which means that they do not have any predators in the ecosystem. Some examples of quaternary consumers are lions, polar bears, sharks, and hawks.

Detailed explanation-3: -Animals in the next trophic level that eat the plants (herbivores) are described as primary consumers. In the next trophic level, predators that feed on the herbivores are identified as secondary consumers. These animals then become prey for the top predator in the food chain level called tertiary consumers.

Detailed explanation-4: -The rat is the primary consumer in the food chain. Rat is eaten by the snake which is the secondary consumer of the food chain or ecosystem. Then the snake can be eaten by the eagle or any other birds that are the tertiary consumer of the food chain. The rat can be eaten by the eagle or tertiary consumer also.
