Definition

Biotic factors are the living components of an ecosystem that directly or indirectly influence the life of organisms in that ecosystem.

Types of Biotic Factors

1. Producers: Organisms that can produce their own food through photosynthesis, such as plants and algae.

2. Consumers: Organisms that obtain their energy by consuming other organisms, including herbivores, carnivores, and omnivores.

3. Decomposers: Organisms that break down dead organic matter, such as fungi and bacteria, returning nutrients to the soil.

4. Mutualistic Organisms: Organisms that engage in mutually beneficial relationships with other species, such as pollinators and their host plants.

Interactions

Biotic factors interact with each other in various ways, including predation, competition for resources, and symbiotic relationships. These interactions play a crucial role in shaping the structure and function of ecosystems.

Impact on Ecosystems

Biotic factors play a significant role in maintaining the balance and stability of ecosystems. Changes in biotic factors can have far-reaching effects on the entire ecosystem, leading to shifts in population dynamics and species diversity.

Study Tips

- Familiarize yourself with the different types of biotic factors and their roles in ecosystems.

- Understand the various interactions between biotic factors and how they influence the overall ecosystem dynamics.

- Explore case studies of how changes in biotic factors have impacted specific ecosystems, such as the introduction of non-native species or the loss of keystone species.

- Utilize visual aids, such as diagrams and flowcharts, to illustrate the relationships between different biotic factors within an ecosystem.

Nature of Science

The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:

Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
