Match each category of organisms with their method of obtaining energy. Producer Consumer Decomposer
Producer - Autotroph that obtains energy and nutrients from nonliving sources. Consumer - Heterotroph that obtains energy and nutrients by eating other organisms. Decomposer - Heterotroph that obtains energy and nutrients from wastes and dead organisms.
