Vikki [24]

<u>Answer</u>: The answers are matched as follows:

African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation

The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters

Humans have been hunting elephants to obtain ivory for many purposes such as making jewellery etc. and earning profits from it. Due to such extensive hunting they have driven the elephants to a level of extinction and thus, this is a form of human exploitation.
  • Mount Saint Helens is a volcano and its eruption which harms the population of the trees in the area is a form of natural disaster since volcanic eruption is a <em>natural</em> <em>phenomena</em>.
  • Fungal infection is a <em>disease</em> which is cause by the microorganisms which harms the population of the Elm trees.
  • Increase of global temperature is a type of climate <em>change</em> and thus, this effect of alteration of migration pattern is caused by climate change.
