Question 5
Question
How would a desert food chain be affected by even hotter temperatures due to climate change?
Answer
The top of the food chain would stop eating, and it would die out.
The bottom of the food chain (Cactus) would no longer have enough water stored up to survive. Therefore, the rest of the food chain could not get its nutrients.
The hotter temperatures would cause there to be more sunlight which would blind the animals and prevent them from hunting.
The cactus would have too much water stored up that it would harm itself.
