A mouse is a consumer. In the ecosystem, organisms are categorized based on their role in the food chain. Producers, such as plants, create their own food through photosynthesis. Consumers, like mice, rely on eating other organisms for energy. Decomposers, such as fungi and bacteria, break down dead organisms and organic waste.
Mice primarily feed on seeds, fruits, and sometimes insects, making them herbivores or omnivores. Since they do not produce their own food and do not break down dead matter, they are classified as consumers. They play a crucial role in the food chain by transferring energy from plants to higher-level consumers, such as predators like owls or snakes.
