Verified step by step guidance1
Understand the environmental challenges of desert habitats: Desert environments are characterized by extreme heat during the day, limited water availability, and cooler temperatures at night. Animals living in these conditions must adapt to survive.
Analyze the options provided: Evaluate each adaptation listed in the question to determine if it aligns with the challenges of desert environments.
Option 1: 'They require large amounts of water daily' - This is unlikely because water is scarce in deserts, and animals typically adapt to conserve water rather than requiring large amounts.
Option 2: 'They have bright coloration to attract mates' - Bright coloration is not a common adaptation for desert animals, as it may increase visibility to predators and does not address the heat or water scarcity challenges.
Option 3: 'They are typically nocturnal to avoid daytime heat' - Being nocturnal is a common adaptation for desert animals, as it allows them to avoid the extreme heat of the day and be active during cooler nighttime temperatures.
