Introduction:
An ecosystem is all the organisms in a given area as well as the abiotic factors with which they interact; one or more communities and the physical environment around them (Campbell, 2012, G-11). Our aim is to observe how these factors interact with each other and give a record of our observations in our particular ecosystem. By observing these interactions we gain an appreciation of the diversity and complex nature of ecosystems. Through observing our environment we can make predictions of the feeding relationships that shape the ecosystem. By observing the plant life in an ecosystem we can predict the following heterotroph factors, as autotrophs are the providers of all energy. Through understanding ecosystems we see that

• Laptop to record number of plant species.
Place chopsticks, or whatever stick objects you have, in the group in a 1x1m2 quadrat with string wrapped around the sticks.
Count the number of plant species in the quadrat sectioning them off into five different groups, trees, shrubs, herbs, grass and moss.
Trees being one singular wood growth while shrubs have multiple stems coming from the ground. Grass is blade like leaves. Herbs are usually soft grass like plants with more leaves then blades. Add these species into your table 1.
Once you’ve completed this extend your quadrat to 1x2m2. Add any additional species, making sure not to count species you’ve already counted in the first quadrat, into your table 1.
Repeat this for sizes 2x2m2, 2x4m2, 4x4m2 and 8x4 meters2. Being sure to only record the new species of plants in the table.
Repeat this process for another area close to your first ecosystem.

The Ecological Systems Theory was founded by Urie Bronfenbrenner. This theory focuses on the impact of the environment on a child’s overall development. The identifying characteristics of Bronfenbrenner’s theory are the five systems used to organize external influences within a child’s development. These systems are the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Each system is aligned with specific interaction levels. The microsystem is considered to be the most intimate of the levels, in which development is dependent on the immediate environment. The immediate environment would include adults, peers, and siblings with influence to learning new behaviors and the environment in which the
Ecological models can answer many questions regarding hypotheses, ecosystem parts and their functions (Marewski & Schooler, 2011). My ecological model was very standard for my teenage years (McWhirter, 2017). I was the first of four children and lived in Ohio, growing up during the ‘60s and ‘70s. We were an average American family living in an average suburb. We all had bicycles and went on bike rides all the time. In the summer, we would ride to the swimming pool in our town. In the summer, we did the book clubs at our library and we always had something to do together with our friends (McWhirter, 2017).

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These
Hypothesis = Marigold being a common species in comparison to the rest would contain the highest biodiversity.
This experiment was a success. The experimental procedure from the lab manual was followed. The right materials needed for this experiment was also used. Each group recorded the data of the name of species and percent cover for species in the three transects. After, the class data was assembled, pie-charts and bar graph were drawn from the data using excel.
Classify plants and animals according to the physical characteristics that they share. Identify the structures in plants (leaves, roots, flowers, stem, bark, wood) that are responsible for food production, support, water transport, reproduction, growth, and protection.
Environmental scanning can be viewed as a way of acquiring information about outside events that can aid organizations in first identifying potential trends, then interpreting them
On March 23, 2010, President Obama signed into law H.R. 3590, the Patient Protection and Affordable Care Act. Since the induction of the Affordable Care Act the Mayo Clinic reached a new goal of 63 million patient services in 2013. (Mayo Clinic , 2014) There has been substantial growth as seen in 2011 they reported just over 20 million patient services. (Mayo Clinic , 2014) The Affordable Care Act has allowed those patients that could not afford health insurance and or issues with pre-existing conditions to finally be able to seek out treatment with the Mayo Clinic. The Mayo Clinic had recognized early on that there would need to be health care reform to ensure the future of quality patient care. In 2006 the Mayo Clinic started the
Tell kids you are looking for descriptive words for the plants like: sticky, pointy, rough, soft, smooth, fuzzy.
Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms. They use carbon dioxide gas and water to produce sugars and oxygen
An ecosystem is a biological community of interacting organisms and their physical environment. An ecosystem consists of biotic factors and abiotic factors. The biotic factors of an ecosystem are the living organisms, while the abiotic factors of an ecosystem are the temperature, climate, sun, and the weather. The ecosystem being researched is the Great Barrier Reef. The Great Barrier Reef is located right off of Australia. The Great Barrier Reef has around 400 types of coral and 1,500 species of fish. It has more than 3000 different reef systems. The Great Barrier Reef is one of the natural wonders of the world, and for good reason.
Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an oak tree, and needed a total of three different trees per group. Once three different trees were chosen, groups needed three shade leaves and three sun leaves of off each different tree. In total, each group should then end up with 18 leaves for testing. After collecting the leaves, we ran them through the LiCor 3100 leaf area meter to identify the area of each leaf. Major results found by the classes’ mutual data was each one of our p-values were greater than .05. This means that we failed to reject the null hypothesis. Thus, the lab results do not support our hypothesis that Quercus acclimation is greater than Acer SLW, size, and sinuosity.
Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There’s not a single plant in sight—no rustling of the leaves, no mighty towering trees to block the severe winds, and the scorching heat of the sun searing upon your face because there’s no shade. And when you take a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body’s activities. What’s wrong with this picture? It’s not possible, of course. Even though plants aren’t the building blocks of life, they’re pretty close and without them, most of life wouldn’t exist—YOU wouldn’t exist. In my research, I will go in-depth about biodiversity—which defines as a quantity of the relative diversity among
