Fellow human citizens of the land, although I am truly pleased to be here and presented upon many different individuals, I bring such somber and dreadful news.
Good evening, and welcome to today's "10 Minute Fact Check". I am Louis Brown, here with Ariel, the Mermaid Princess, talking about the serious issues that several marine habitats have been going through recently.
Hmm.. the carbon cycle? Deforestation? What do they have anything to do with marine environmental problems?
Countless marine creatures are suffering due to global warming and atmospheric warming, mostly caused by anthropogenic, or artificial, activities such as deforestation and industrial combustions of fossil fuels. They all cause dramatic disorder within the carboncycle, bringing devastating results to our environment.
Very well. I would have to explain the carbon cycle first, then.
The carbon cycle is the exchange of carbon compounds between all of the earth’s components—the atmosphere, oceans and rivers, rocks and sediments, and organisms. The processes of photosynthesis and respiration are the basis of the carbon cycle.
Carbon is an abundant element that is crucial for all existing life on Earth to grow and thrive.
Carbon enters the aquatic food web through autotrophs, or primary producers that can make their own food, such as algae of marine plants like seaweed. They capture the carbon dioxide or bicarbonate ions to produce glucose. Heterotrophs, or organisms that can’t manufacture their own food thus must take nutrition from other sources, consume these organic molecules(autotrophs).
Carbon cycles also occur within marine environments!
As the primary consumers like crabs and krill are eaten by secondary and tertiary consumers such as sharks and whales, the organic carbon that were originally made by autotrophs, continues to be passed through the food web. However due to the law of energy transfer where only 10% of energy from the lower trophic level can be transferred to the next trophic level.
Then eventually, to release the energy stored in carbon-containing molecules, such as sugars, autotrophs and heterotrophs break these molecules down in a process called cellular respiration, where the carbons of the molecule are released as carbon dioxide. Decomposers also release organic compounds and carbon dioxide when they break down dead organisms and waste products
