Answer:
a. series of chemical reactions necessary for the use of the raw material.
Explanation:
The term metabolism is used to describe the various chemical reactions in the body that meet the structural and energy needs of a living being. Among the purposes of these chemical reactions, we can mention the synthesis and breakdown of biomolecules, energy production and the conversion of nutrient molecules into macromolecule precursor units.
Metabolism is not unique to humans and occurs in all living beings, whether unicellular or multicellular. The reactions that make up metabolism can be classified into two major metabolic processes: anabolism and catabolism.

Answer:
- An ecosystem consists of a community of organisms together with their physical environment.
- Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
- In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
- Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.
