Predator in the Ocean

ecosystem, the predators of the ocean are overfished. Predators such as salmon and tuna are fished quite frequently because they are used in dinners around the world. Clearly then, as the predators rapidly decrease, the primary and secondary consumers overpopulate. Science News states, “We’ve eliminated the marine equivalent of lions and wolves and are moving towards the taking of rats, cockroaches, and dandelion equivalents.” (https://www.sciencenews.org/) Clearly then, when predators are eliminated

Chemoreceptors are primarily responsible for taste and smell, two vital functions for an organism’s survival; using smell for detecting predators and taste for locating

The Netflix documentary series, The Blue Planet: A Natural History of the Ocean, discusses the complexity of the mystified ocean while also asserting the vast influence it has on the earth. In this episode, titled Frozen Seas, the documentary compares the coldest regions in the world- the Arctic and the Antarctic. In this, the narrator illuminates the differences in temperature and climate, land and ice, predators, and organisms within the two polar regions. First opening with the introduction

industrialization, cement production, and other land-use changes. The ocean absorbs much of this excess CO2 through air-sea gas exchange, resulting in changes in seawater chemistry. Due to human-made emissions, the CO2 content of the oceans has dramatically increased and is gradually acidifying the surface waters. As a result of human-made emissions, the amount of CO2 in the atmosphere and oceans has increased dramatically during recent decades. In the ocean, the accumulating CO2 is gradually acidifying the surface

group in the Northern part of the Pacific Ocean. This whale belongs to the dolphin family, and is considered the largest in that family. The whale is also known as orca and has teeth. Most of them feed on diverse diet, but individual whales have their own prey. There are those who feed on fish, while others hunt for dolphins and seals. They are known as apex predators because no animal can dare to prey on them. They are cosmopolitan and can be found on any ocean in the world. These whales are social

The Oceans are the most diverse biomes in the world, for they cover 71% of the planet. Life in the ocean evolved 3 billion years prior than land, and it still has over ¾ of all the habitats on Earth. Humans have always posed threats to the delicate marine environment, yet it still is thriving. Without the marine biome humans and other animals alike would not be in existence, for evolution of the first life would never have occurred, and we would not have a strong enough atmosphere to support life

Ocean acidification (OA) is a global threat because 25% of carbon dioxide (CO2) is absorbed into the ocean and it decreases its pH value. Through the process of OA, the amount of carbon molecules taken in create an unbalance in the waters’ acidity level. The oceans’ chemistry can try to find equilibrium by joining the extra carbon molecules with those of oxygen, but there will not be copious oxygen molecules to be paired up with the carbon molecules. Turning the oceans’ water solubility more acid

focusing on why sharks should not be culled. If the top predator of a food chain is removed, then that may cause the end of many more species. By removing the top predator of the food chain, this interrupts and disrupts the entire food chain and the animals on it. Firstly, sharks play a significantly important role in the ocean as most sharks serve as top predators and are at the top of the food pyramid and so they play a vital role in the ocean ecosystems. They hunt old, weak and or sick fishes in

was dominant by the dinosaurs but the oceans were populated by more rich and diverse marine reptiles. There were more than a dozen different groups of marine reptiles in the Mesozoic era, these groups contained pelagic and coastal predators and coastal herbivores. The three main predators of the oceans were the

has been labeled as the apex predator of the sea. With the increase in human population the demand for shark meat and fins are at an all time high therefore, the existence of the shark is becoming a concern. Individuals are observing to think of sharks as a negative feature to the environment, which is prolonging the effect to prevent shark species from becoming extinct. With that in mind, not only are human over-fishing sharks, but also the CO2 emission into the ocean are also at an all time high
