Study Notes
Biotic Factors in Ecosystems
- Biotic factors refer to all living organisms within an ecosystem.
- These organisms interact with each other and their environment.
- Examples of biotic factors include:
- Plants (producers): Carry out photosynthesis to create their own food.
- Animals (consumers): Obtain energy by consuming other organisms.
- Bacteria and fungi (decomposers): Break down dead organisms and organic matter, releasing nutrients back into the ecosystem.
- The relationships between these organisms, such as predation, competition, and symbiosis, are crucial to ecosystem dynamics.
- Populations of various species within an ecosystem can interact in complex ways, such as food webs, illustrating the interconnectedness of life.
- The presence and abundance of different species of plants, animals, and microorganisms significantly affect the overall health and functioning of an ecosystem.
- Biotic factors influence the physical environment, such as the amount of oxygen in the atmosphere and the soil composition.
- Interactions between biotic factors are essential in nutrient cycling and energy transfer.
- Plants, as producers, form the base of most food webs, supporting other trophic levels.
- Biotic factors, in combination with abiotic factors (non-living components of an ecosystem), shape the structure and function of the entire ecosystem.
- Each biotic factor plays a specific role in the ecosystem's processes.
