Question

Global warming and climate change is altering environmental niches, causing:

• A. Movement of thousands of ocean species poleward from the equator
• B. Terrestrial organisms to adapt and become marine
• C. Species to rapidly increase in number
• D. Accumulation of helium gas in organisms

Answer 1

The correct option is A Movement of thousands of ocean species poleward from the equator

Climate change is altering environmental niches, causing species to shift their habitat range as they track their ecological niche. In fact, species (both plants and animals) are being affected by climate change, and as they reach their ecological limit, they need to shift their habitat just to survive.
Following shifting temperatures, some species of animals and plants have shifted their geographic ranges poleward (to the north in the northern hemisphere and to the south (in the southern hemisphere) or even moved to higher altitudes.
