Detailed explanation-1: -The energy roles within an ecosystem are producer, consumer, and decomposer . Organisms that make their own food by using the sun’s energy to turn water and carbon dioxide into food through a process called photosynthesis.

Detailed explanation-2: -The living parts of an ecosystem include animals (consumers), plants (producers), and fungi and micro-organisms (decomposers).

Detailed explanation-3: -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Detailed explanation-4: -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. Scientists distinguish between several kinds of consumers.

Detailed explanation-5: -Herbivores eat plants, carnivores eat meat, and omnivores eat both. Predators are animals that eat a prey animal. Scavengers eat organisms that are already dead. Decomposers break down dead plants and animals into component parts, including nutrients.
