Lab Report Biodiversity

The sixth lab I completed in Biology 101 taught me how autotrophs (self-feeders) and heterotrophs (other-feeders) make organic food molecules by using photosynthesis. Photosynthesis uses the energy from the sun and it is captured and stored in the chemical bonds of organic molecules. The sunlight consists of different wavelengths of light. In plant chloroplasts, they have different pigments that capture different wavelengths of light. Light capturing pigments in green plants are called chlorophylls and these absorb all the colors of light except green, which is mostly reflected. To separate molecules from each other according to their solubility in a particular solvent is done by the process of chromatography. This basically means that polar

3. Soil samples were collected at varying distances from the lake at 10m increments (0-40m) using the shovel and meter stick. Soil samples were only collected from a depth of about 2-8 inches.

Species evolve over time because of competition, adaptation, and environment. This is determined through history of a species. Competition includes agility, speed, and strength. Adaptations depend on changes in environment. History shows evidence in proving species evolve over time.

With your partner, get an agar plate and wax pencil. On the bottom of the plate, draw a cross that separates the plate into fourths. Put A-D on each quarter of the cross and put your initials on the plate.

The high evenness is due to fewer species being present at this site. The results of this lab supported my hypothesis that the water’s edge would have the highest biodiversity, the wooded area would have medium biodiversity, and the manicured lawn would have the lowest biodiversity. The reason that the results support my hypothesis is that the water’s edge had a diverse vegetation around it for a variety of species to be found. It also had the pond where species could be found. The wooded area contained many layers of leave coverage which is good for some species but bad for others. The wooded area is also subject to runoff which reduced the number of small species that could be found on the ground. The manicured lawn is cut often causing a reduced amount of species that would be found on the ground and not enough trees to counteract the cutting affect. The biodiversity of the three sites are comparable by the evenness being greater with low species richness. The sites are also comparable by the shannon diversity index being higher as the species richness is increased. An ecological explanation that we observed was that an area with low evenness were less likely to interact with each other. The area with a higher evenness would

The final project of the Spring 2018 Foundations of Biology lab focuses on investigating variation in a population. As a class we study population variation to better understand evolution and the mechanics behind it. What is the basis of evolution? The basis of evolution is the differences in the alleles carried by the members of the population in their genome. The differentiation in allele frequency accounts for a majority of the observable hertable differences in a population. Specifically in this project we are anaylzing variation in the population of our Foundations of Biology class. The main objective of this experiment is to investigate the genetic variation in the Foundations of Biology class by looking at two specific

Microbes ate my homework Soil and nutrients investigation Tina Shen Grade 9/3 Introduction In this experiment we investigated the effect of microbes on different types of paper. The aims of this practical were to find out how fast the soil microbes decomposed different types of papers, to explore the role of soil microbes in the carbon cycle and to introduce the use of enzymes in industrial processes. Hypothesis (my predictions): The paper types containing nutrient broth and soil will decompose faster.

Biodiversity accounts for the difference in life throughout our planet. The different animal kingdoms throughout ecosystems is the most notable example of biodiversity. Biodiversity is the entire spectrum of species that live in the biosphere. A small pond such as the ones that will be sampled are ecosystems to frogs, lilies, and insects and an

Humans have manipulated their environment for their own purposes since the beginning of time. Nature has provided humanity with many valuable necessities. Similarly, the term "biodiversity" is the variety of life within species, ecosystems, and ecological systems (Simpson, 2002). Biodiversity allows species to prosper in their environment (Liu, Zhang, Hong, 2011). The benefit of a diverse system is the services it contributes to humanity and its function in the ecosystem. (Nelson, 2014). In addition, in the article “Why biodiversity is important to the functioning of real-world ecosystems,” the author states, that from a practical view of the policy of GDP, the primary matter should be the possible outcomes of the loss of certain species that

The standard deviation was approximately the same for both habitats, which indicates that the variation in the data was the same. This suggests that the vegetated area is more biologically diverse than the open-water area. Simpson’s index of diversity is also higher for the vegetated area, 0.82, compared to the open-water area, 0.68 (Table 1). A higher value of Simpson’s index of diversity also indicates higher diversity in the vegetated habitat.

It consists of every ecosystem, every living thing and genetic makeup existence. Without biodiversity, life cycles cease to exist. Let me explain. Without pollination from the bees, fruits and nuts would not exist and without plants and trees, there would be no oxygen. Some scientist believe that due to mass population growth, the consumption of resources and the need to expand and build to accommodate the mass population, our natural ecosystems have become disrupted and on the verge of extinction. According to an article by Damian Carrington entitle “the sixth extinction, he explains that the domination of humanity has allocated species to relocate to ecosystems unfamiliar, creating a disarray and destroying biodiversity (Carrington, 2018). In this case, human impact is imperative to changing this crisis. By raising awareness and making lifestyle changes, humans can improve our ecosystem. Some of which include reducing use of chemicals, preserving nature and planting more

Humans have existed since 200,000 years but the Earth has existed around 4.5 billion years. Nature has provided us with everything we have today - food, medicines, materials, chemicals, metals, minerals etc. It can only keep providing us when we maintain the right environment for it to exist. This environment depends on the biodiversity of Earth. The number of species of plants, animals and microorganisms and the various genes in these species, different ecosystems such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Hence Biodiversity impacts everything. We will discuss how Biodiversity plays a crucial role on social, environmental, and economic factors. We will also discuss what

Biodiversity is what makes the planet earth unique and different from every other planet in the solar system. Biodiversity can be studied on a global level all the way down to studying it within a microscopic ecosystem (National Wildlife Federation, 2015). It is important to understand that biodiversity can be looked at genetically as well as environmentally as well. For example, genetic biodiversity is seen in the variation of different breeds within the dog species, while environmental biodiversity is the diversity of ecosystems and habitats (National Wildlife Federation, 2015). Preserving biodiversity is perhaps the most important task that humans have to complete while living on this planet. The ecosystems that make up all of the regions worldwide are immensely complex, so conservation may be difficult at times. Additionally, many factors influence the species that inhabit ecosystems, and these factors may complicate the preservation of biodiversity. Moreover, there is a plethora of threats to biodiversity, both natural and manmade that are destroying ecosystems on a daily basis. Out of these threats, the human influences are particularly severe and must be taken care of at all costs. Biodiversity provides countless benefits for every ecosystem and creature, which is what makes it worthy of conservation. Through the introduction and relocation of species, some degree of restoration may be possible in the future. Biodiversity is an amazing natural process that makes life

Biodiversity provides the basis for ecosystems and the services they provide, upon which all people fundamentally depend. People rely on biodiversity in their daily lives, often without realizing it.

Biodiversity term used for the variety and variability between all types of living organisms such as microorganisms, plants and animals available in a particular area covered by natural conditions. The term biological diversity first coined by Norse and Mc Mangus in 1980 (Rawat and Khare, 2010). According to the U.S. Office of Technology Assessment (1987), biological diversity is the variety and variability among living organisms and the ecological complexes in which they occur. Biological diversity fabricates variability of gene, species and ecosystem (P.D.Sharma, 2015). It is essential for maintain the basic process on which life depends and is a key to sustainable development (Jerath and Chadha, 2006). The heterogeneity of the environment increases the number of resources and results in a higher diversity. Agitation is one of the main factors affecting variation in species (K. Premalatha, 2013).
