Final answer:
Temperature is an abiotic factor, while hawks, fir trees, and beavers are biotic factors within an ecosystem. Water snakes are biotic and not abiotic factors. These components interact to determine the characteristics and distribution of organisms within different habitats or biomes.
Step-by-step explanation:
The ecosystem's biotic and abiotic components interact in ways that define a biome and affect the distribution of organisms. In the given questions, all the options except temperature are biotic factors in the first case, and all the options except water snakes are abiotic factors in the second case.
Biotic factors such as hawks, fir trees, and beavers are living elements of an ecosystem that interact with abiotic factors like temperature, soil, and rainfall, all of which are critical for establishing the conditions of a given habitat or biome.
Abiotic factors such as temperature, type of soil, and rainfall are nonliving components that directly impact the type of flora and fauna that can survive in an ecosystem, thereby affecting the migration and distribution of species through influencing conditions like moisture and nutrient availability.
