Mesotrophic Chlorophyll a is the photosynthetic pigment that causes the green color in algae and plants. Fjord lakes can also form from the action of glaciers carving steep fjord valleys and depositing rocks, boulders, and soils — moraine — at one end of the valley, forming a lake. Oligotrophic lakes: Lakes of low primary productivity and low biomass associated with low concentration of nutrients (N and P). Question 4.1: Explain the formation of a chemical bond. Answer. G. Evelyn Hutchinson. How Many Types Of Lakes Are There? When ice sheets moved over flat rock surface with weakened areas of fissures, the rock could splinter and loosen to form the basin of “glac… Intermediate Lakes These lakes, in spite of considerable shore and surface use, are relatively intact as natural re-sources. A lake with low primary productivity, the result of low nutrient content. The lakes are classified into how many types on the basis of productivity? However, in the context of lake use and assessments such a classification is of little value. Lake thermal structure is determined by several factors. The Questions and These terms facilitate communication and understanding about agricultural crops or potential crops for various purposes such as crop selection for gardening or crop farming, research and development, and plant collection. Can you explain this answer? The trophic status of a water body is usually estimated by values of primary production meas-ured for the growing season. Apart from being the largest Chemical Engineering community, EduRev has the largest solved In developed lakes, richness was best described by positive linear lake area, negative linear productivity, and linear and quadratic development terms. However, in the context of lake use and assessments such a classification is of little value. In addition, we include lakes with episodic partial deep water renewal, where a process can be identified that recharges and replaces part of the deep water on a regular basis. Grouping of lakes and reservoirs is therefore traditionally attempted on basis of depth, water chemistry and conductivity (e.g. Jan 03,2021 - The lakes are classified into how many types on the basis of productivity?a)2b)3c)4d)6Correct answer is option 'C'. Mixing and Stratification. Henderson and Welcomme, 1974, Ryder et al., 1974, Downing et al., 1990). These lakes are deep and carry more water than could ever be evaporated. These lakes tend to be saturated with oxygen throughout the water column. By continuing, I agree that I am at least 13 years old and have read and agree to the. The classification of lakes based on succession and productivity 1 Oligotrophic, The classification of lakes (based on succession and productivity), Young lakes are often times limited in the amount of nutrients, The water is turbid (cloudy) because of nutrients, Not much lake left because it is almost full, water will always follow the path of least resistance, water will always create habitats or microhabitats, production is pretty high in most streams, always getting inflow of nutrients from surrounding landscape, lower part of the stream has more nutrients because of flow, “you never step into the same stream twice”, Streams do NOT freeze because of constant temperature, Temperature is an important factor for stream life, Riffle: shallow area where flow increases, Aufuchs: the word for lots of attached algae, Lots of microhabitats develop from flowing water, Pool: the deeper segments of the stream where flow is reduced, Pool bottom is filled with softer sediments, Species diversity drops in pools because there are few microhabitats, Lots of burrowing since there is a soft bottom, Hard substrates are more diverse than soft substrates, Possesses suckers, hooks, or fictional pads for clinging to substrate, Animals with long antennas that serve as protection on land are a LIABILITY in a, stream, so these structures are therefore reduced, Clams in streams have a thicker and heavier shell that ones in a lake, Moving upstream counters from being knocked back downstream, Streams receive a lot of nutrients from the water that washes in, Streams depend on the input of materials from 3 energy sources, CPOM: coarse particulate organic matter – leaves, mostly large debris, FPOM: fine particulate organic matter – originate from CPOM, DOM: dissolved organic matter – particles in a solution, Invertebrates may be grouped ecologically by trophic activities and diets, Shredders: feed on CPOM, bacteria, and fungi growing on CPOM, Collectors: feed on FPOM (mostly from broken down CPOM), Piercers and Scrapers: feed on algal cells growing on substrate. Consumption pattern of production 5. Based on comparative lake sampling in 2004, seasonal predictors of algal primary productivity were identified within subsets of similar lakes using a combination of Akaike's information criterion (AIC) and classification and regression trees (CART).
