Final answer:
Temperature is an example of an abiotic pressure in an ecosystem, which is a non-living factor that influences the dynamics and distribution of living organisms within an ecological community.
Step-by-step explanation:
An example of an abiotic pressure in an ecosystem is b. Temperature. Abiotic pressures are non-living chemical and physical factors in the environment which affect ecosystems. Examples of abiotic factors include sunlight, temperature, rainfall, and soil quality, all of which have significant impacts on living organisms and the overall health and structure of ecosystems.
Abiotic factors like temperature are critical in shaping the natural world, impacting the types of species that can survive in a particular habitat and influencing the interactions between different species. These factors can create pressures that lead to changes in population sizes, distributions, and the outcome of competition for resources within a community. Hence, understanding the role of abiotic pressures is fundamental in the study of ecology and the dynamics of ecosystems.
