It focuses on the relationship between humans and the environment. The Cell. Exam 1 Notes.docx - Exam 2 Notes.docx - Exam 3 Notes.docx. Viruses. of them will be able to use that resource more efficiently than the other and eventually will drive that second species to extinction locally, The excluded species can emigrate to another location in order to survive, Fundamental: the niche that an organism occupies in the absence of competitors, Realized: the niche that it occupies under natural conditions, Predator: organism that captures other organisms for food, Prey: organism that is eaten by the predator, Plants: plants will release chemicals to inhibit digestion by animals, Some herbivores retain the plants toxins and become poisonous themselves, Commensalism: where one organism benefits and the other is not affected, Nutrients are stored in plants and rapidly recycled, Almost half of all terrestrial organisms live here, Typically covered with grass and scattered trees, Transitional between tropical rain forest and desert, Desert plants store water (succulents) and have extensive roots, Most animals are nocturnal (active at night) to avoid the heat, Critical factor is water (behavior and physiology adapted to conserve water), Abundant rainfall and seasonal temperature changes, Grasses are the most common plant (few trees), Grazing animals very common: horses, rabbits, cows, Distinct seasons (winter, spring, summer, fall), Many varieties of plants (perennial) and animals, Chaparral: evergreen scrub-type plants common in Mediterranean-type climates, Long, cold winters with little precipitation, Most of the precipitation occurs in the summer, Extensive coniferous forests (pine, hemlock, fir), Many large animals (moose, elk, bear, deer, etc), Found at high latitudes and very cold places, Most of the water is trapped in the permafrost located a few feet below the surface, Neritic zone (shallow waters along coasts), Abyssal zone (deep water - dominated by decomposer organisms and, Limnetic (photic) zone: area of light penetration, Profundal (aphotic) zone: area without light penetration, Thermocline: the abrupt change in temperature at the border between the epilimnion and the hypolimnion, Water achieves its maximum density at 4 C, During winter, surface waters cool and sink removing the thermal stratification, This allows nutrient-rich deep water to rise to the surface, Nutrients are now available in the spring for productivity, Commercial and industrial: factories, businesses, Chemical (industrial wastes, personal wastes), Non-biodegradable: cannot be broken down naturally, Renewable: capable of being replaced within a lifetime, Non-renewable: not capable of being replaced, CFC's released into the atmosphere will break down the ozone layer, Destruction of ozone will increase the UV light reaching the earth, Soil is not very fertile and becomes unusable in a short time, Global surface temperature is thought to be increasing. Tentative lecture outline: This is likely to change as we go along! Sign Up. Earth Science. rainforest, desert, tundra, etc the study of these distinctive patterns throughout the biosphere is called “ecology” ecology: the study of organisms’ interactions with their environment & with each other General Kinds of Ecosystems all the world’s ecosystems can be grouped into just a Pollution: contaminating the environment, B. For eg, termites create a 6 feet tall mound and at the same time feed and protect their entire population. Ecology can be classified into different types. It deals with factors that alter and impact the genetic composition and the size of the population of organisms. For example, a polar bear can thrive in the sub-zero temperatures of the Arctic, but it cannot survive in warmer climates such as the tropics. Therefore, Biology is the science of Living Things. ZOOLOGY. It deals with the exchange of energy, materials, organisms and other products of ecosystems. It emphasizes the impact human beings have on the environment and gives knowledge on how we can improve ourselves for the betterment of humans and the environment. Ecology plays a significant role in forming new species and modifying the existing ones. Ecology is the branch of science that deals with the relationship of organisms with one another and with their physical surroundings. The different types of ecology are given below: It deals with interactions among earth’s ecosystems, land, atmosphere and oceans. Ch 29.

Crystal clear and simple. All organisms require energy for their growth and development. The different types of ecology include- molecular ecology, organismal ecology, population ecology, community ecology, global ecology, landscape ecology and ecosystem ecology. ECOLOGY. With the knowledge of ecology, we are able to know which resources are necessary for the survival of different organisms. Biotic components are living factors of an ecosystem.
