In the context of the word "endangered," it typically has a denotative meaning when referring to species that are at risk of extinction. However, if it is used in a more figurative sense to describe a situation or aspect that is at risk or in danger (like "endangered values" or "endangered communities"), it could have a more negative connotative meaning.
To provide a specific answer, I would need to see the paragraph in question. If the word is used in relation to wildlife or species, the answer would be "denotative meaning." If it refers to a more abstract concept at risk of being lost, it would likely lean towards "negative connotative meaning."
