matrenka [14]
Assuming this is supposed to be a multiple choice question- I think the correct answer would be “early onset of spring change in marine ecosystems” because it looks like the question is asking what it wouldn’t affect, and I’m sure if the people had to leave, that animals would’ve all had to leave as well!

Answer:

<em><u>D. The first flowering plants were introduced toward the end of the Mesozoic era.</u></em>

<em><u /></em>

Explanation:

Following the Paleozoic Era, the Mesozoic Era or <em>Age of Conifers</em> began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.

The Mesozoic era is marked by 3 divisions:

  1. the Triassic Period,
  2. the Jurassic Period,
  3. and the Cretaceous Period.

Animals and plants slowly recovered  after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.

By the end of the <em>Mesozoic Era</em>, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the <em>Triassic</em>, and the conifers, cycads and gymnosperms of the <em>Jurassic</em>.

<em>Varied dispersal  mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.</em>
