Detailed explanation-1: -Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both.
Detailed explanation-2: -Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.
Detailed explanation-3: -Food Chains Plants make their own food through a process called photosynthesis. Using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food.
Detailed explanation-4: -Consumers obtain energy by feeding on producers (eg. plants) or by feeding on organisms in the trophic level below themselves.
