Over utilization , or also referred as overexploitation of species is very serious problem. The loss of one species can affect many other species in an ecosystem.Some examples of animal species that are over utilised are:
1. Woolly Mammoths - The hunting of the last surviving woolly mammoths greatly contributed to their decline and extinction.
2. Dodos - these proverbial birds went extinct in the mid-to-late 17th century and their disappearance is directly attributable to human activity.
3. Polar bears - Polar Bears have become endangered in large part because of global warming and climate change in the Arctic.
4. Muskox - they nearly became instinct because of over-hunting throughout the late 1900s until the 1930s.
5. Great White Sharks - the largest predatory fish on Earth are victims of "finning" by fisherman, essentially, stripping the fins from the shark then tossing them back in the water to die or be eaten alive.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
