How Does The Greenhouse Effect The Environment?

How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide?

1. For this experiment, what were the independent variable and the dependent variable? What were the constants?

The reaction time (in seconds) is the dependent variable of this experiment. This will be changed by the temperature of the chemicals, and as it is affected by the independent variable it is considered the dependent variable.

How do water vapor, carbon dioxide, and nitrogen levels differ between land with recent prescribed burns, natural burns, and a control, with no recent burns?

In, "Tropical Spiderwort ( L.) Increases Growth under Elevated Atmospheric Carbon Dioxide," they did a study with invasive plants when they are put in an environment with elevated CO2. In this experiment they focus on the weed, Tropical spiderwort (Commelina benghalensis L.), specifically since it is a major invasive plant in the southeastern United States of America. They found that this plant has different changes to it from the elevated CO2. There was an increase in the number of flowers and leaves that was created on the Tropical spiderwort, but the height and root size of the plant did not increase. It was the plant put most of its biomass towards the steams rather than the roots. The total dry weight of the plant had a significant increase

The dependent variable is rate of fermentation, which will be measured by the amount of carbon dioxide produced.

Dependent and independent variables: The dependent variable is the plant placed on the window sill. The independent variable is the inches that the plant grows per day.

Observation: A higher density of plants were observed to grow near a source of water with the plant density decreasing as the distance to the water source increased.

The independent variable is the salt solution concentration. The dependant variable is the mass of the potato. The control variable is the distilled water.

The release of carbon, however, was released in four phases. First, there was a large release of carbon over the initial 10 years, then it slowed down the next seven years, after the seven years, the emissions resumed, until stopping again recently. The author ends the article hinting that some sort of feedback loop is happening that favors certain organisms that consume carbon in the soil.

The hypothesis was that carbon was the factor that impacted plant mass the most. According to the data, this is accurate. although the plants that had 10 tablets grew the least, they still had the most mass, meaning that the carbon increased the mass of the plant regardless of how much it grew. The first set of data showed that the amount of carbon affected the more carbon, the more mass there was. The second set of data mirrored this. The first set of data for the mass gain for the control was 6.9 grams, the plant with two tablets had a mass gain of 10.6 grams, the plant with five tablets had a mass gain of 16.3 grams, and the plant with ten tablets had a mass gain of 30.6 grams. For the second set of data, the control had a mass gain of 6.5, the plant with two tablets had a mass gain of 8.5 grams, the plant with five tablets had a mass gain of 5.4 grams, and the plant with ten tablets had a mass gain of 46.5 grams. The average mass gain for the control was 6.7 grams.

The effect of chloroplasts on the growth of a plant Purpose: The purpose of this experiment is to determine how different factors affect the rate of photosynthesis. Hypothesis: If the amount of chloroplast relates to photosynthesis then it is predicted that the more chloroplast present in the leaf the more oxygen bubbles produced because the function of chloroplasts is to capture energy from sunlight and use it to conduct photosynthesis, without this organelle photosynthesis would be impossible diminishing rate of photosynthesis.

In temperate zones, the growing season comes at a certain time of the year and results in a fluctuation of the carbon dioxide concentration. Carbon dioxide is only removed from a system in temperate regions during the day. So the concentration of carbon dioxide is lower in the day and higher at night; this diurnal fluctuation is more pronounced during the growing period. Plants photosynthesize during the day and by just as the sun is past its zenith in the sky, the concentration of carbon dioxide is at its lowest. As the temperature increases and the relative humidity decreases the rate of synthesis of carbon decreases. As a result, net primary productivity begins to decrease becoming zero when there is no sunlight. At nightfall, because there

What should be done with the remaining variables that can alter the height the ball bounces to?

What's more, raised carbon dioxide levels are not necessarily a bad thing. In a study done by Achim Walter, increased carbon dioxide in the available atmosphere increased cell production and cell expansion of Populus deltoides. Plants in general show increased photosynthesis when influenced by raised carbon dioxide levels. It was determined that the larger leaf area exhibited by Populus deltoides did not come about by larger leaves upon emergence by growth. This also accounts for
