How do biotic factors impact an ecosystem?

• A. They solely affect climate patterns.
• B. They affect population dynamics and the interactions between species.
• C. They dictate the availability of non-living resources.
• D. They are independent of abiotic factors.

Answer: (B)

In an ecosystem, biotic factors are the living components that interact with each other and with the non-living elements (abiotic factors) of the environment. These factors include all forms of life, such as plants, animals, fungi, and microorganisms. When considering the impact of biotic factors on an ecosystem, they play a crucial role in influencing population dynamics, which refers to how species populations change over time due to reproductive rates, death rates, immigration, and emigration. Additionally, biotic factors encompass the interactions between species, such as predation, competition, mutualism, and parasitism. For instance, the presence of a predator can control the population of prey species, which in turn affects the plant life that the prey might consume. Thus, the correct answer emphasizes that biotic factors directly shape the relationships and dynamics among different species, significantly influencing the overall health and sustainability of an ecosystem.
