This lab consisted of the use of various materials. We used four orange flags in order to mark a 30x15m sampling area in which we collected our data from. To measure out the area‚ we used a thirty meter measuring tape and to determine the density (plants per meter squared) of clovers in the lawn‚ we calculated the total area of the plot (30x15meters squared). For this lab‚ a frisbee was used with the area of .053 meters squared as the quadrat. We used a frisbee for a couple reasons. A frisbee was

diversion are decrease sediment downstream of dam and decreased water volume in waterways down/upstream. The decrease in sediments downstream of dams causes nutrients not to transfer so without valuable nutrients plant and animal growth is decreasing. The decrease in water volume in waterways is interfering with the reproductive cycle of plants and animals downstream. For example‚ the Chinook salmon aren’t able to spawn since there were trapped from moving back upstream by dams which formed large pools

minerals‚ thus offering the growth of diverse plants. There are many trees which are as old as 100-200 years. It is nature which enables the germination of seeds and saplings in the forest over a period of time. Some areas of forests have understoreys‚ that is layer of giant trees‚ followed by tall trees and then by shrubs and herbs. The plants and animals present in forests vary depending on the climatic and environmental conditions. Forests rich in nutrients: There are several insects and dead‚ decaying

Contrary to their name‚ sowbugs (Porcellio laevis) are tiny crustaceans that live in moist environments around the world. These creatures‚ about 12.5 mm in length‚ are extremely unique in their physiology‚ habitat‚ diet‚ and behavior. Sowbugs are harmless to humans‚ but incredibly important to ecosystems. They are found easily in nature‚ and are quite hardy (Franklin‚ Julie A.) Though they use gill-like structures‚ called pseudo tracheae‚ to breathe‚ sowbugs cannot breathe underwater but are highly

Plants can make their own food through photosynthesis and then break it down for usable energy through the process of cellular respiration. Analyze and explain how your life might be different if you could make your own food through photosynthesis. First of all if we were to be able to make our own food trough photosynthesis‚ we should have chlorophyll‚ which is the important pigment in absorbing sunlight. As an effect we will all be green in color. This may be good as there will be only one race

shuttles in orbit. Fungi are thought to be about 400 million years old. The study of fungi is called mycology‚ which is a branch of biology. Fungi are not plants or animals. Like plant and animal cells‚ fungus cells are eukaryotic‚ meaning they have a defined nucleus. Like plants‚ fungi are sessile‚ or unmoving. Their cells are similar to plant cells‚ but do not contain chloroplasts. This

Fire’s Role in the Ecosystem A Balancing Act Scientists have studied forests and fires to determine the secret of Nature’s success in attaining this necessary balance. They have learned that a "natural" fire results from a certain fuel condition. Some forest types produce and accumulate fuels faster than others; some decompose fuels more readily than others. However‚ at some point in time‚ every forest type has fuel of the right quantity and quality for that forest to be "ready" to burn. In the

the only known planet that has conditions suitable enough for living organisms to grow‚ reproduce and survive. These conditions are a combination of non-living components like water‚ sunlight‚ temperature and living components like micro-organisms‚ plants and animals. The non-living components of a particular environment that make the conditions ideal for sustenance of life are known as the abiotic factors. Some of the important abiotic factors that affect living organisms are: Water Water can

A Biome is all of the life zones‚ all plants‚ animals‚ and other organisms‚ as well as the physical environment in a particular area. A biome is characterized by its plant life‚ which is determined by its location. For example‚ northern coniferous forests exist in sub-arctic portions of North America and Asia‚ but further north‚ the conditions are simply too harsh and the season too brief for trees to grow. Instead of trees‚ the short vegetation of the tundra thrives in these areas. The same occurs

thing‚ such as an animal or a plant‚ is called an organism. There are seven characteristics of living organisms – Nutrition Nutrition is the process by which organisms obtain energy and raw materials from nutrients such as proteins‚ carbohydrates and fats for growth and repair. Photosynthesis is the process of nourishment of green plants. Digestion is the process of nourishment of green plants. Respiration Respiration is the process of the breakdown of nutrients (glucose) to release energy
