Verified step by step guidance1
Understand the concept of limiting factors: Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of an organism or a population in an ecosystem. These factors can be biotic (living) or abiotic (non-living).
Review the examples provided: The options include availability of water, amount of sunlight, type of organism's scientific name, and number of predators. Consider which of these directly impacts the survival or reproduction of organisms in an ecosystem.
Analyze each option: Availability of water and amount of sunlight are abiotic factors that can limit plant growth and, consequently, the entire food web. The number of predators is a biotic factor that can regulate prey populations.
Evaluate the exception: The type of an organism's scientific name is not an environmental condition and does not directly influence the survival or reproduction of organisms. It is a classification tool used in taxonomy, not a limiting factor.
Conclude: The correct answer is the type of organism's scientific name, as it does not function as a limiting factor in an ecosystem.
