Trends In the Ocean

By jamielynn

  • Introduction

    Abiotic factors of the ecosystem has impacted the ocean. Some abiotic factors include burning fossil fuels, decrease of pH in the ocean, ocean acidity, and increase of carbon dioxide.

  • Burning Fossil Fuels

    Fossil fuels are hydrocarbons, fuel oil, natural gas, and coal that are formed from the remains of dead plants and animals. Burning these fossil fuels makes the carbon dioxide levels increase. The increase of carbon dioxide makes greenhouse gasses, causing global warming. Burning fossil fuels produces more carbon dioxide in the atmosphere, heating up the oceans.

  • Increase carbon dioxide

    The increase of carbon dioxide warms up the ocean causing ocean acidity.

  • pH in the ocean

    The average pH balance today is 8.1. A healthy pH balance for the ocean is 8. Having a higher or lower pH balance affects biotic factors in the ocean. Ocean acidity causes the ocean pH balance to drop. In the past 200 years, ocean water became 30% more acid.

  • Ocean Acidification

    By not having carbonate in the ocean, the shell's of animals will become weaker, and will not be able to survive their enviorment. Less carbonate also causes coral bleeching. Ocean acidification makes an unequal ecosystem, and it affects the ocean.

  • Coyotes in the City

    Coyotes in the city relates to this, because the biotic and abiotc factors influence both coyotes and ocean's ecosystem. For the coyotes it is humans invading their territory. For the ocean the pH balance and carbon dioxide affect how biotic and abiotic factors survive in the ocean. Both ecosystems are affected by outside influences.
