Answer:

prokaryotes

Explanation:

Prokaryotes were the first living beings to appear on earth, about 3 billion years ago. By evolution, prokaryotic cells gave rise to eukaryotes.

At the beginning of our planet, the first forms of life should have a very simple cellular organization. This is because the planet still had inhospitable characteristics that would be unable to support more complex life forms. In this scenario, prokaryotes would be the organisms most likely to survive and thanks to their existence, the most complex forms of life were able to exist.

Four examples of the effects of environmental change are given. Match each one with the type of environmental change it demonstr
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

An infection with a fungus reduced the population of North American Elm trees ----> disease

Increasing global temperatures have altered migration patterns of humpback whales ------>climate change

<u>Explanation</u>:

  • <em>Human</em> <em>exploitation</em> is the unethical or selfish use of resources to satisfy their own personal needs or for any profitable activity which harms the resources in such a way that they get limited. 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.
