Iguanas are ectothermic reptiles that rely on external light sources to regulate their body temperature and metabolic processes. They are sensitive to UVB light, which is essential for synthesizing vitamin D3, crucial for calcium metabolism and bone health. In their natural habitat, iguanas bask in sunlight to absorb warmth and UV rays, while they often seek shade to avoid overheating. Their circadian rhythms are also influenced by light, affecting their activity patterns and behavior throughout the day.
Iguanas are cold blooded reptiles. Without light/sun, they lose body heat.
Earthworms do not respond to darkness per say, but they do respond to light. although they do not have eyes, they are light sesitive.
Iguanas are picky.
Domestic iguanas do.
Iguanas eat dark, leafy, green veggies. Mostly animals bigger than iguanas will eat them.
yes iguanas are herbivores
yes they respond very well
Your retina has more than one type of cell that perceives and transmits light. Cones are cells that respond to color, but they respond best in bright light. In very dim light, the cells that respond to light are called rods, which are blind to color.
yes
iguanas have a spiky tail to whip predators. (:
Iguanas do not have a prehensile tail.
Plants respond to light through a process called phototropism, where they grow towards light sources to maximize photosynthesis. Light is essential for plants to produce energy through photosynthesis, so they have evolved to detect and respond to light cues for optimal growth and development.
