Multiple choice

Which conservation strategy focuses on preserving genetic diversity within a species?

  1. Habitat restoration

  2. Ex situ conservation

  3. Captive breeding

  4. Reintroduction
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Captive breeding programs aim to preserve genetic diversity within a species by breeding individuals in controlled environments and reintroducing them to the wild to increase genetic variation.

Multiple choice

  1. Ex situ conservation

  2. In situ conservation

  3. Habitat restoration

  4. Reintroduction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ex situ conservation includes the establishment of gene banks, where genetic material from various species is stored for future use in conservation efforts.

Multiple choice

Which conservation strategy involves the establishment of corridors between fragmented habitats?

  1. Habitat restoration

  2. Reintroduction

  3. Invasive species control

  4. Habitat connectivity
