Answers
Biotic components or biotic factors, can be described as any living component that affects another organism, or shapes the ecosystem. This includes both animals that consume other organisms within their ecosystem, and the organism that is being consumed. Biotic factors also include human influence, pathogens, and disease outbreaks. Each biotic factor needs the proper amount of energy and nutrition to function day to day.
Biotic components are typically sorted into three main categories:
Producers, otherwise known as autotrophs, convert energy (through the process of photosynthesis) into food.
Consumers, otherwise known as heterotrophs, depend upon producers (and occasionally other consumers) for food.
Decomposers, otherwise known as detritivores, break down chemicals from producers and consumers (usually antibiotic) into simpler form which can be reused.
Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.
Biotic factors include plants, animals, fungi, algae, and bacteria. Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability.
