1141 . A remarkable ecosystem teeming with biodiversity lies in the heart of the Amazon rainforest. The intricate web of life in this dense and lush environment has fascinated scientists for decades. One of the most captivating inhabitants of the Amazon is the poison dart frog, known for its vibrant colours and potent toxins.

Interestingly, scientists have discovered that the frogs toxicity is linked to their diet in the wild. When raised in captivity and fed a different diet, these frogs do not develop the same level of toxicity. Despite their diminutive size, poison dart frogs have captured the attention of researchers studying chemical compounds. Some of the toxins produced by these frogs have potential applications in medicine, particularly in the development of painkillers. What conclusion can be drawn about the relationship between the poison dart frog's diet and its toxicity?
- A. There is a direct link between diet and toxicity
- B. Diet has no impact on toxicity
- C. Toxicity increases with captivity
- D. Toxicity is solely determined by genetics
