The nutrients that are produced through decomposition at the bottom of the aquatic environment are locked out from the warm surface water due to the thermocline. Phytoplankton, which are at the base of the marine food chain and are primarily marine plants found in surface waters. The lack of nutrients in surface waters in the tropics hinders high productivity of phytoplankton and zooplankton, which plays a role in the crystal, clear appearance of the water. In temperate waters, the thermocline (year long in tropical) is only the summer and breaks up in the fall allowing the nutrient rich bottom to mix with the surface water. Climate change allows for several high and low blooms of plankton through changing seasons.
Which makes them significant to economies. The Pacific ocean, because the plates plunge beneath the mantle in this area. Hydrogenous sediment is formed when minerals crystallize in ocean water due to many types of chemical reactions. They come from trenches and shelves. They are used for making concrete.
Geology is the study of the dynamics and physical history of earth including changes earth go through and rocks that are composed. Oceanography is the study of the ocean including waves, tides, currents and the ocean floor. The branch that interests me the most is oceanography. This branch of earth science is very interesting. When you look at the ocean you don’t really think about what makes waves, or about what’s in the water or the tides and currents.
The water in the cup also has the lower water concentration and osmotic potential; therefore water inside the snail migrated towards it, rendering the snail void of water. The snail does not have the adaptation to maintain its optimal salt and water levels (Hart et al. 1991, as cited in Jadap et al. ) and live under such salinity. This places the snail in the stenohaline category (Baldwin, Brock, Nielsen, & Rees, 2003).
They are cracks in the ocean floor that emit hot water loaded with minerals and bacteria. 2) How is food made at a vent? Animals are able to survive because the water coming from the vents are not only rich in minerals but also in chemosynthetic bacteria. The animals depend on this bacteria to survive. They do this by turning the bacteria into another source of energy to make food.
Optimum nutrition is a very important aspect needed to enhance optimum health. Nutrition is often controversial, and at times misleading through false advertising and conflicts of interest amongst policy makers. There are many factors that influence a persons overall health. This essay aims to highlight the significance of eating a healthy balanced diet, as well as looking at other factors that may contribute to ones lack of health. The definition of nutrition is the “basic physical resources necessary for energy production, growth, reproduction and the proper functioning of tissue and organs” (Webster-Gandy, Madden & Holdsworth 2012, p.2).
3. What does it mean to eat a balanced diet? A balanced diet is defined by a proper and monitored intake of food to provide energy for the body. The old adage that “too much of a good thing is bad” sums it up quite accurately. A balanced intake would mean to only consume enough carbohydrates, a particular mineral or vitamin for the body to properly function.
Pre Lab Questions: 1. Explain the reasoning behind the classification of biological hotspots. * A biological hotspot is an area that is rich in biodiversity but is being threatened of extinction 2. What reasons are there for classifying Madagascar and the Indian Ocean Islands as biological hotspots? * Madagascar and the Indian Ocean were once a place of high plant and animal diversity and population however, in the last 1500 years people have come into this untouched environment impacting these species due to their lack of knowledge on human involvement.
He went beyond specific details by arranging these needs in a hierarchical fashion. Certain human needs are more fundamental than others, and satisfaction of these "basic" needs is necessary before "higher" needs can be addressed. He divided these needs into two levels. The first level of needs is physiological needs: The most basic needs of oxygen, food, water, and maintenance of body temperature (food, water, health, breathing (air), shelter, & clothing) commonly satisfied in first world countries. These needs are important for the maintenance of the body.
Naturopath's focus, amongst other things, on achieving optimum nutrition needed by clients to obtain optimum health. In times when diet may not be able to fully provide optimum nutrition, herbal medicine or supplementation may be considered to bridge the gaps in an individual's nutritional needs, in order to achieve their best state of health. 'Let your food be your medicine and let your medicine be your food' (Hippocrates, ND) Food is a fundamental aspect of our everyday lives. Much more than just experiencing pleasurable sensations when enjoying good food, our diets provide our bodies with the energy, carbohydrates, proteins, essential fats, vitamins and minerals to live, grow and function properly. Eating a balanced diet is essential for good health and well-being.
