The correct answer is 'd'.
Explicación
## Step 1In an ecosystem, there are two types of factors that can affect the size of a population: abiotic and biotic. Abiotic factors are non-living elements such as temperature, light, and soil minerals. Biotic factors, on the other hand, are living or once-living organisms in the ecosystem. These can be plants, animals, fungi, and bacteria.## Step 2In this question, we are asked to identify a biotic factor that can affect the size of a population. The options provided are oxygen concentration, severe weather, different kinds of soil minerals, and populations of predators.## Step 3Among these options, only "populations of predators" are biotic factors. Predators are living organisms that can directly affect the size of a population by preying on other organisms.
