A
Availability of nesting sites

D
Presence of non-predatory insects
Verified step by step guidance1
Understand the concept of a limiting factor: A limiting factor is an environmental condition that restricts the growth, abundance, or distribution of a population within an ecosystem. It can be biotic (living) or abiotic (non-living).
Analyze the options provided: Evaluate each option to determine whether it directly impacts the toucan population's ability to grow or reproduce.
Option 1: Availability of nesting sites - Nesting sites are critical for toucans to reproduce and raise their young. If nesting sites are scarce, this would limit the population's growth.
Option 2: Abundance of sunlight - While sunlight is essential for photosynthesis in plants, it is not directly a limiting factor for toucans, as they do not rely on sunlight for reproduction or survival.
Option 3: Stable atmospheric pressure and Option 4: Presence of non-predatory insects - Neither of these options directly limits the toucan population. Stable atmospheric pressure is not a direct factor, and non-predatory insects are a food source but not a limiting factor compared to nesting sites.
