METHODS Freshwater ecosystem is also known as aquatic ecosystem that are contrasted with marine ecosystems and high salt content. Freshwater habitats are classified by different factors such as temperature, light, penetration and vegetation. In this assignment, the freshwater ecosystem that was analyzed covered two sites which were the freshwater river at the Gombak Forest Reserve and the Sungai Gombak along the residential area. From both site 1 and site 2, the environmental conditions and invertebrate’s species were analyzed. Students were divided into group of 8 and were given a fishing net to collect the samples of invertebrates and fishes. All samples were then transferred into a white plastic container for observation. Conversely, a water meter kit was also used to test for the pH and oxygen content of water. All samples collected were then analyzed using freshwater ecosystem vetebrates guides and the identification were recorded down onto a datasheets. Nevertheless, most of the results …show more content…
In site 1 which is the freshwater river at the Gombak Forest Reserve, the three different types of invertebrates found were mayflies, water cockroach and leaches. In site 2, which was Sungai Gombak at a residential area, the three different types of invertebrates found were tadpoles, water scorpions and butterflies. The difference in the invertebrates found from both the sites was known to be due to the presence of different environmental parameters that is suitable for the invertebrate’s life cycle. For example some invertebrates prefer breeding in freshwater that had low conductivity and high amount of vegetation for feeding, (Koop et al. 2008). However, some invertebrates prefer polluted and muddy water for breeding. Therefore, the variation in environmental conditions can be a factor in the changes of the invertebrate’s life cycles and daily
The taiga biome has many marvelous elements that make this biome unique and in the taiga has one special animal, and that animal is the Lynx. The taiga biome has different temperatures in the spring, summer, fall and winter. Also, the taiga needs abiotic and biotic elements to live and give shelter to the other living things in the biome. The taiga has a lot of other animals but one extraordinary animal that lives there is the Lynx . The taiga and the Lynx are very unique things in this world.
The Eutrophication test determines the amount of nutrients there are in a stream, creek, or most bodies of water. When we did the Eutrophication test we got a lot of low numbers. For the Phosphate test they were mostly a 0 with a .1. When we did the nitrate test we got .25, .75, 1, 1.2, 1.5, 1.3, and a .9. for the dissolved oxygen tests they were all mostly high results.
Abstract: The main focus of this lab is on animal behaviors in terrestial isopods, also known as pillbugs. There are many purposes to this lab experiment. First, these pillbugs are put into four different types of enviroments, also known as chambers, light v. dark, hot vs. cold, moisture vs. dry, and lastly shelter vs. open. In these different chambers, there are 10 pillbugs, 5 placed into each individual chamber and then observed for up to 5 – 10 minutes. In this lab we observed that pillbugs prefer light areas, hot temperatures, moist environments, and lastly sheltered spaces.
Whites Creek was initially a natural watercourse, concreted to improve sanitation in the surrounding area. Over the years it was transformed into a natural park, with an array of services, including tables for picnics, BBQ areas and a skateboarding zone. The Whites Creek Wetland was also constructed, being a sediment and purification pond that aims to remove water from Whites Creek stormwater waterway and pass it through a natural purification system. This system would then filter the water back in the water channel and out into the Sydney Harbour .
Valerie Beketova Dr. Bennett AP Environmental Science 10 December 2015 Chapter 14 Outline Earth is a very dynamic planet Earth is made up of different layers: - Core - interior made up of dense, extremely hot metal, mostly iron. It is the most inside layer of earth. - Mantle - hot, pliable layer that surrounds the most inner layer, the core. It is less dense than core.
Case 2: Chesapeake Bay watershed System Complexity, Data, and Impairment Description The Chesapeake Bay watershed is an example of a complex modeling system that consists of a large watershed (165,759 km2) with flow-regulated rivers, large urban centers and expansive rural areas, and an estuary (US EPA, 2010). The Chesapeake Bay TMDL allocates total nitrogen, total phosphorus, and sediment loads to reduce the size of the oxygen-depleted zones in the bay to restore its living resources. As such, estimating nutrient loads from all sources (air and land) and assessing their effect on the bay’s aquatic life requires the use of an integrated modeling framework. Because of the areal extent and system complexity of the watershed and the estuary, the Chesapeake Bay TMDL is one of the most complex TMDLs conducted in the United States.
phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.
The book addresses aquatic and terrestrial ecosystems. At the beginning of the text a vocabulary page outlines the essential words for understanding. Bold faced words highlight the key vocabulary. This text contains many opportunities for students to ask question and respond to their reading. Illustrations cover the page to support the text.
A stream with a great abundance of life would probably have a measurement of or near seven, which is near neutral, or the measurement may be a little higher. For a stream that is not as productive, the pH measurement may be higher or lower than seven. For the alkalinity test, the average was thirteen. An alkalinity test tells you if there are limestone, which neutralizes acid. The average amount of rocks that did neutralize acid was sixty five, while the average amount of rocks that didn’t neutralize acid was twenty nine.
The high amount of limestone in the creek neutralized the acid rain that was pouring on the creek. This can also make ph scale go into the alkaline side of the ph scale. The ph scale is healthy, because if it was to acidic it will be unhealthy for the fish. These were some of that factors that were in the
The earth is covered with 70% of water in the form of seas, oceans, lakes, and rivers. These water bodies act as marine habitat for different animals and plants to live, by providing suitable environmental conditions. There marine habitat is broadly divided into two types, they are Coastal, open ocean habitat and Deep ocean. [1] Coastal habitat: Coastal habitat is located along the coast line of water bodies.
Abstract/Background: This experiment was to observe the interaction of Isopods with abiotic and biotic factors. The Isopods were found in a garden and brought in the the lab. In the lab, each group of students pick a control variable and a dependent variable. Problem: In this experiment, Isopods will be observed to see if paper saturated with the color blue is preferred over paper that is saturated with the color green.
Tropical rain forests, which are found in Africa, South America and Southeast Asia, have warm, humid climate and heavy seasonal rainfall (Supriatna et al. 1996; Umapathy et al. 2003). The rainy season lasts from about September to May, with average monthly rainfall between 140 and 300 mm (5.5 and 11.8 in) and from June through August or September there is less rainfall received in Southeast Asia (Lucas & Corlett 1991; Yeager 1996; Umapathy et al. 2003). Besides, tropical rain forests are home to world’s highest biodiversity including a highly complex and diverse vertebrate fauna (Harmelin-Vivien & Bourliere 1989). However, tropical rain forests are always manipulated and exploited for economic purposes (Mergen, 1981).
Referring to ecological systems theory (in Chapter One), explain why parents of children with genetic disorders often experience increased stress. What factors, within and beyond the family, can help these parents support their children’s development? Be sure to include in your response information from the textbook or other psychology-specific sources. Parents of children with genetic disorders often experience increased stress because, based on Urie Bronfenbrenners’ ecological system theory, a child’s social and physical attributes and capacities can affect adult’s behavior, (Berk, L., 2014). According to this theory, parents of a child with a genetic disorder are more likely to be more impatient because of the behavior the child may have.
Many communities are impacted by exotic species that are introduced over time (Lankau 2009). These exoctic species can result in either positive or negative effects on the community through interacting with the native species (Lankau 2009). Exotic species are moved by humans outside of their native range; species become invasive when they cause harm to their new environment. Earthworms are exotic in many areas that they are introduced to over time. Earthworms are a major influence on soil composition, but to this day there is still many unknown factors about the species (Zirbes L et.
