All detritivores are decomposers because they both consume dead organisms. But not all decomposers are detritivores. Detritivores (detrit = wear down into bits, vore = to eat; have mouths and eat dead bits of plants and animals. Some examples include worms and certain insects (pill bugs, millipedes).rganisms that consume secondary consumers are called tertiary consumers, and so on. Some organisms consume by absorbing food (ex. fungi and bacteria). Some organisms consume by eating with special adaptations called mouths (and sometimes teeth or beaks).
