Investigating The Co2 And Temperature Changes From The Outside Environment

7.”CO2 is plant food” - While plants do absorb carbon dioxide, too much of it will

Ecosystems maintain themselves by recycling energy and nutrients obtained from external sources. At the first trophic level of primary producers i.e. plants and algae, use solar energy to produce organic plant material through photosynthesis.

Damon Matthews, a professor in Concordia University’s Department of Geography, found a direct connection between carbon dioxide and global warming. Matthew’s studies show that same global temperature increase, regardless of when or over what period of time the emission occurs. The effect of adding more carbon dioxide is predicted in the theory of greenhouse gases. Swedish scientist, Syante Arrhenius, first proposed the theory in 1896, based on earlier work by Fourier and Tyndall. At the same time, many scientists have reached the same conclusion. If we increase the amount of greenhouse gases in the atmosphere, the Earth’s temperature will increase. Energy is absorbed from the sun in the form of visible light and ultraviolet radiation. The earth then releases some of this energy as infrared radiation. Greenhouse gases in the atmosphere captures some of this heat, then re-emit it in all directions. During this process, carbon dioxide and other greenhouse gases keep the Earth’s surface 33 degree Celsius warmer than it would be without them. According to an ongoing temperature analysis conducted by a scientist at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8 degree Celsius. Since 1975, two-thirds of the warming has occurred at a rate of roughly 0.15-0.20 degree Celsius per decade.

Biobottle Write-up In the biobottle experiment, the purpose was to create a closed ecosystem, containing biotic and abiotic factors, which aimed to sustain life without contact with the outside world throughout a period of six weeks. For the procedure, the ecosystem was to be observed over this time. The experiment began when a one-quart mason jar with its contents was sealed on October 7, 2015. In the beginning of the experiment, the known contents of the jar and initial rationales behind them (italicized) included: ● Water from the middle pond filled to the 600 mL mark of the jar (about 550 mL): the environment for the aquatic ecosystem with enough room for gases at the surface ● Pond mud filled approximately halfway between the bottom and 100 mL mark of the jar: source of nitrogen and miscellaneous organisms ● 2 small sandstones: phosphorus used for phosphorus cycle ● 1 stick: for animals to use for movement ● 1 leaf: nitrogen;

With climate change and extreme depletion of Earth’s natural resources since the Industrial Revolution, it is important to analyze sustainability in terms of ecology, which means analyzing the environmental impacts of experiment 4.

We, as a species, are altering levels or carbon dioxide dramatically. According to NASA, concentration levels of carbon dioxide haven’t been as high as they are now for over 1,000,000 years and that the rate of change CO2 levels in the past five years is alarming.

Ecology has been the study of different interactions amongst organisms with the abiotic environment (Pimm and Smith, 2007), examining how ecosystems have thrived upon these relations. Ecosystems have depended on the continued availability of energy supplied ultimately by plants through the process of photosynthesis. Plants have lived in association with each other from having occupied the same niche in nature (Khan and Hussain, 1999). Numerous plants have

Greenhouse gases are the main factor to the poisoning of Earth’s atmosphere. Gases in the atmosphere that absorb radiation and have a big impact towards the greenhouse effect are known as the Greenhouse gases. The greenhouse effect happens to be one of the major causes of global warming. According to the Environmental Protection Agency (EPA), some of the major greenhouse gases are methane, carbon dioxide, water vapor and nitrous oxide. (Lallanilla, 2015). There are multiple places all over the world who suffer from dangerous levels of greenhouse gases in the air due to the over-pollution to the air. The first step to taking on such an issue is to detect and then monitor the problem so that in this case, the greenhouse gases do not get out of hand. Crucial importance to the future of Earth relies on the monitoring and detecting greenhouses gases and the best way to do so is by the use of orbital satellites. The use of remotely sensed data can be used to measure greenhouse gas emissions in the atmosphere, thus helping authorities to make better decisions related to climate change.

Our modern use of animal agriculture is one of the biggest threats to our environment. Due to the massive amounts of carbon dioxide, methane, and nitrous oxide emissions, animal agriculture has become one of the leading causes of air pollution and climate change. When heat energy from the sun arrives to Earth, the energy must either be captured or escape. The atmosphere plays a major role in capturing that heat energy, making our planet warm enough to support life, like us. While these naturally-occuring molecules are necessary for our survival, if these substances become too abundant, it may damage our ecosystems. In the event that these molecules become overly common in our atmosphere, they begin to retain too much of that sun energy, causing a phenomenon known as global warming, or climate change. Climate change can lead to unstable weather conditions, melting of glacial

Ecosystem is made up of all populations living together and the physical factors with which they interact with their environment. The ecosystem gets its energy from the only source, the sun, which make it important. The sun plays significant roles in ecosystem functioning of photosynthesis. In this lab, we will focus mostly on population and community ecology. Population ecology is a group of organisms of the same species living in the same place at the same time. Factors that affect the number of individuals living in a habitat are the population growth rate, size, birth and death rates. Community ecology focuses on the interactions between organisms as to preys and predators. These will lead to the causes that affect animals population; including

The tale of the human race and our connection to the ecosystem can be viewed as an unfolding adventure shrouded in mysterious occurrences. The impacts of the overall climatic change have signaled danger for a long time, and it is clear that there is a global crisis facing us. One would wonder where we are headed and if the earth will be able to sustain life in the next century. Global warming continues to manifest itself to us every day through rapid changes occurring to the climate system. Some of us still hide from reality and hold on to the notion that climate change is just, but another scientific

Plants and several other photosynthetic organisms use light energy to change water, carbon dioxide and minerals into oxygen and organic compounds packed with energy. • Variables: • Independent variable: The distance between the light source and the plant, that is inside the beaker. I will change the independent variable, which is the light intensity, by exposing it into five different distances (5, 10, 15, 20 and 30 cm). • Dependent variable: The amount of oxygen bubbles produced.

Aerobic respiration is the intake of glucose and oxygen and the production of CO2 and ATP, heat, and water. This experiment was conducted to show whether saran wrap can have an effect on the aerobic respiration of the aquatic plant, Elodea. For example, whether it will increase it or decrease it. By recording the amount of drops of 0.02N NaOH it took for the water to turn a certain shade of pink, we were able to determine the amount of CO2 that was present. Thus we were able to tell what effect sealing the beakers with saran wrap had on Elodea. We sealed two beakers, one with elodea and one without. Two other beakers were not sealed, one had the plant and one also did not. the results showed that there was no significant difference in the amount of CO2 that was present in the beakers sealed with saran wrap irrespective to having a plant in the water or not. A reason for this this result might be that the incubation period was not long enough for actual, significant results to occur.

Climate change is a critical issue that affects the Earth in a large-scale way. Humankind is primarily responsible for the Earth’s warming. Understanding why climate change is happening is crucial to be able to decipher solutions.

The world continuously faces a variety of threats every day, from natural disasters to terrorist, but one threat that society predominately contributes to all on their own, is climate change. There are many feasible explanations for the global threat of climate change. These explanations include but are not limited to, the act of deforestation to the rainforest and other trees, green house gas emissions, and sulfate aerosol, which cause poor air quality.
