refers to a condition when the number of the population exceeds the capacity of their living habitats and the existence of their resources, it normally occurs from the unbalanced rate of birth and deaths, an increase in immigration, or an unsustainable biome and depletion of resources. Overpopulation is generally considered as a disadvantage as it may contribute to multitudinous problems such as environmental deterioration, low life qualities, good deficiency, and fatal issue such as population collapse

Biodiversity Lasnosha Snowden ENV 300 Environmental Science Nicole Minor June 15, 2015 All living organisms are present in ecosystems to coexist together to create biodiversity and without different species, these environment could fail horribly. Every living organism has a purpose in order to keep the balance of biodiversity. In order for there to be “biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular

BIODIVERSITY Biodiversity is the degree of variation of life. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet. Terrestrial biodiversity tends to be highest at low latitudes near the equator, which seems to be the result of the warm climate and high primary productivity. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in mid-latitudinal band in all oceans. Biodiversity

the Puget Sound area. It accounts for more than $100 million in the state of Washington’s economy (Radtke, 2011). Fisheries are the study of the ecology of fish in a given environment. In oceanography it is defined as ecological organization of a biome, community, population, or species (Govoni, 2005). There are many different sectors of fisheries to study. For example, abundance and distribution of different fishes, human impact, and the study of the physical processes are difference

Question 1 Most insects use external sources of heat to achieve their operative temperature range. Heinrich's research on the sphinx moth (Manduca sexta) indicates that some insects can thermoregulate by using their flight muscles and: A. using their blood as a coolant. B. decreasing their metabolic rate. C. possessing an internal respiratory system. D. using a countercurrent heat exchange mechanism. Question 2 The thermal stability of aquatic environments is a result

Chemistry 1. 5 points of the particle theory: * 1. All matter is made up of tiny particle with empty spaces between them * 2. Different substances are made up of different particles * 3. Particle are always in constant random motion * 4. Particles of a substance move faster as the temperature increases * 5. Particles attract each other 2. Changing state from solid to liquid to gas: * form a solid when the forces are strong enough to form a rigid shape * they gain
