Organisms that digest molecules in organic material and convert them into inorganic forms are called decomposers. They are classified as heterotrophic since they use organic substances in obtaining the energy and nutrients they need to survive. They are organisms that are responsible for breaking down decaying organisms into simple molecules in order to bring these back to the biogeochemical cycles into the ecosystem. In the food chain, they are the last step. Examples of these decomposers are fungi, snails and some insects. These organisms do not have an internal digestive organs since the the organic substrates undergo biochemical reactions only.

Answer:
The correct answer is omnivores
Explanation:
Primary consumers: are those animals which feed on plants, also called herbivores.
Secondary consumers: animals that feed on primary consumers or/and other animals, e.g carnivores(eat other animals) and omnivores(eat both animals and plants).
Detritivores are organisms that feed on dead or decaying plants or animals such as bacteria.
So, from the options mentioned, omnivores can be considered as both primary and secondary consumer
Answer:
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
