Explanation:

• 31: In biological classification, the family level is more specific than the order level. Since tigers and lynx are in the same family, they are more closely related.
• 32: Preventing invasive species from entering an area (option D) is the most effective long - term strategy. Once they are established, physical removal (A) can be difficult, using another invasive species (B) can cause more problems, and using a disease (C) may have unintended consequences.
• 33: Kikuyu grass with a long photosynthetic period can out - compete native species, making it likely an invasive species (A).
• 34: A species only found in one specific location (Madagascar in this case) is an endemic species (B).
• 35: Demography is the study of populations (A). Taxonomy is classification, a dichotomous key is for identification, and dichotomy is a division into two.
• 36: The Endangered Species Act (D) in the US aims to conserve species on the brink of extinction.
• 37: Invasive species (A) are often well - adapted to new environments and can reproduce rapidly, making them least likely to go extinct.
• 38: Endemic species (B) have a limited range, so they are more vulnerable to extinction.
• 39: The current mass extinction is mainly caused by human activities (D) including habitat loss, hunting, and climate change (which is also influenced by humans).
• 40: Preserving habitat (C) is the best way to preserve biodiversity as it supports a wide range of species.
