Answer:
consumers
Step-by-step explanation:
All living organisms require energy to perform their life processes. Some organisms derive this energy by feeding on other organisms. These set of organisms are referred to as CONSUMERS in Ecology.
All consumers are heterotrophic organisms i.e. organisms that depend on other organisms for energy source (food). Therefore, the Panda that feeds on bamboo, which is a plant, is a CONSUMER because it depends on another organism to get energy. Specifically, the Panda is a primary consumer because it feeds directly on a producer/plant (bamboo).
