Habitat Loss

• Habitat is the physical and biological
  environment used by an individual, a population
  or a species
• Habitat degradation is the process by which
  habitat quality for a given species is diminished
  
• Habitat loss occurs when the habitat quality for
  a given species is so low that the environment
  can no longer support the species

5
Ecosystem Loss

• Ecosystem is a group of organisms and their
  physical environment
• Ecosystem degradation occurs when alterations to
  an ecosystem degrade or destroy habitat for many
  of the species that constitute the ecosystem
• Ecosystem loss occurs when the changes to an
  ecosystem are so great and so many species
  typical of that ecosystem (especially dominant
  species) are lost that the ecosystem switches
  from one type to another
