Annual Sunflower

One of the world's most cultivated flowering plants and an economically critical oilseed crop, sunflowers are native to North America and can reach 3 meters in height with flower heads up to 30 cm across. Their distinctive behavior of tracking the sun — solar heliotropism in young plants — gave them their name. A single sunflower head consists of up to 2,000 tiny individual florets. Global production exceeds 50 million tonnes annually, valued for oil, seeds, and birdfeed.

koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
