16. Changes in habitat are a major threat for native species and can lead to species loss. A habitat change that is harmful is:   habitat decommission, or the breaking up of several larger habitats into smaller pieces of habitat, even if they are well connected. habitat heterogeneity, or the diversity of a habitat in physical make-up. All of the choices are true. habitat degradation, or the decreased value of a habitat used by species.

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
