I chose this picture because if in the future agricultural, economic, social, and political practices go unchecked I think finding a job would be hard. If we didn't develop an economic sustainability there wouldn't be many business. Communities wouldn't prosper; financially unsuccessful. If we stop developing a sustainable community it would be a hard place to live

The most influential chemical that is derived from a plant is called Aspirin. It is derived from a handful of plants including Salix alba (white willow), Spirea spp. (wintergreens), and Betula spp. (birch). They come from a tree called cinchona tree. Aspirin is a popular treatment for pain, inflammation, and fever. I chose this chemical because when I'm hurting i consume this pill. It was interesting to know where it came from.

I chose this video because it provides a timeline from how agriculture started to the inventions that came from it. It explains that new agricultural practices were created to help farmers all over the world. Farmers could now eliminate hunger by improving the output and quality of crops. Farmers could now use the same amount of land to grow crops with the new technology that was invented.

The Agricultural Revolution in 18th-century Europe was a time of growth and improvement for the farming and agriculture industry. Learn more about the timeline, causes, inventions, and effects of new farming techniques, such as crop rotation and improved livestock utilization, which led to new types of crops, land patterns, and social change throughout Europe. Updated: 09/22/2021

Historians have often labeled the first Agricultural Revolution (which took place around 10,000 B.C.) as the period of transition from a hunting-and-gathering society to one based on stationary farming. During the 18th century, another Agricultural Revolution took place when European agriculture shifted from the techniques of the past.

New patterns of crop rotation and livestock utilization paved the way for better crop yields, a greater diversity of wheat and vegetables and the ability to support more livestock. These changes impacted society as the population became better nourished and healthier. The Enclosure Acts, passed in Great Britain, allowed wealthy lords to purchase public fields and push out small-scale farmers, causing a migration of men looking for wage labor in cities. These workers would provide the labor for new industries during the Industrial Revolution.

The Agricultural Revolution began in Great Britain around the turn of the 18th century. Several major events, which will be discussed in more detail later, include:

The perfection of the horse-drawn seed press, which would make farming less labor intensive and more productive.

The large-scale growth of new crops, such as potato and maize, by 1750.

The passing of the Enclosure Laws, limiting the common land available to small farmers in 1760.

Contributing Factors to the Agricultural Revolution

In many ways, British agriculture advanced more rapidly than any other European nation. The increased agricultural production of the 18th century can be traced to four interrelated factors:

The increased availability of farmland

A favorable climate

More livestock

Improved crop yield

Let's look at each of these areas in more detail. The available farmland increased due to changes in landholding patterns spurred on by new methods of cultivation. Previously, the open-field system was prominent. This system was problematic because it allowed part of the land to remain unplanted at all times in order to avoid depleting the soil. Since growing crops removes nutrients from the soil, a field must be replenished in order to continue to yield food.

One solution to this situation was to continue to move crops to different land. This was not feasible in Great Britain because the country lacked a large percentage of available land. Instead, farmers began to utilize barren soil by planting different crops, such as clover or turnips.

These plants have roots rich in nitrogen, a necessity for replenishing soil. The cultivation of turnips was important because they could be left in the ground through the winter. This ultimately led to an increase in livestock because these plants were also utilized for grazing. The boost in livestock fundamentally changed the diet of much of Europe.

Not only were Europeans consuming more meat, but the livestock was producing much needed fertilizer for crops. The addition of fertilizer allowed an improved production rate per acre. By the beginning of the 18th century, the colder climate of the 'little ice age' had ended. The resulting mild summer months created ideal conditions for crop cultivation.

Important Inventors

Several innovators created tools that greatly influenced the new agriculture. For instance, a significant step forward was pioneered by Jethro Tull, an English agriculturist.

The Neolithic Revolution had various impacts on human population. One major impact was was the rise of civilizations. Farmers were delivering much more food than they required for their families, not every person needed to cultivate, so others had the option to have various jobs. In addition, specialization within society was made possible. This permitted the discovery and improvements of different technologies.

I believe that the most in danger biome is the Grassland biome. It has been converted to crop productions, forest plantations, urbanization and other land uses such as energy and mining development. I think this is the most altered and yet the least protected. Animals are losing their homes.

I chose this video because it goes into depth in explaining the process of photosynthesis. Plus the drawings and the details help me visualize what really happens. Sunlight as mentioned in the video does more than keeping us warm, "it provides most of the energy that we and other animals use for fuel."

The Photosynthesis Reaction

Many of us appreciate the warmth of the sun when we're on the beach or anxiously waiting for the arrival of spring. But the sun does more than keep us warm - it also provides most of the energy that we and other animals use for fuel. How? When we eat a salad or crunch on an apple, we're eating sugars made by a plant through photosynthesis. Photosynthesis is the process in which some organisms capture light energy from the sun and change it into chemical energy. But how can we tell if photosynthesis is occurring in a plant?

Let's start by reviewing the overall biochemical reaction. The process of photosynthesis can be summarized in the general equation:

2 H2O + CO2 + light energy --> carbohydrate (CH2O) + O2 + H2O

The physical reactants in this equation are water and carbon dioxide; the products are carbohydrate (sugar), oxygen, and water.

Experimental Design

Reaction rate, or how quickly a chemical reaction takes place, can be measured in a laboratory by looking at either how fast reactants disappear or how quickly products are formed over some period of time. So in this case, we can decide to measure how fast water or carbon dioxide disappear, or how fast carbohydrate, oxygen, or water are formed. For simplicity, let's eliminate water, since it's both used and formed. And for ease, let's count out carbon dioxide disappearance, since to do that properly, we would have to start with a closed system and measure a colorless, odorless gas. That leaves us with carbohydrate or oxygen formation. To help us decide which of those to measure, let's take a very quick look at leaf anatomy.

The leaves of most plants have a layer called spongy mesophyll. The spaces in this layer are full of O2 and CO2; these gases cause leaves to float if we drop them in water. If we start by creating uniformly sized leaf disks by using a hole punch, then remove the gases in the leaf disks by using a vacuum, the disks will sink in a beaker of aqueous solution. We can then determine a rough estimate of how quickly oxygen is formed through photosynthesis by measuring how fast the leaf disks float to the surface of the liquid.

We actually get an estimate of the rate of net oxygen formation, since the plant cells are also undergoing active cellular respiration, using oxygen to create energy. All we need to do is add light, water, and, since we removed the existing CO2, a source of carbon dioxide. We can add these last two by immersing the leaf disks in a solution of water and baking soda.

Let's start by showing that water and carbon dioxide and light are all necessary for photosynthesis by creating a basic experimental setup of three beakers: one with leaf disks in light and water; one with leaf disks in light, water, and carbon dioxide; and one with leaf disks in water and carbon dioxide but no light. Notice the results - only the leaf disks that have all of the reactants will float.

Results and Analysis

Let's repeat the procedure we just described, and this time, compile some data. For simplicity, we'll just create two conditions. Condition A, leaf disks in distilled water and light, will be our control condition, and condition B, leaf disks in bicarbonate solution and light, will be our experimental condition. Let's assume we put ten leaf disks in each beaker and keep all of the other variables constant. Knowing that the experimental condition differs from the control condition because it contains all of the reactants needed for photosynthesis, what prediction would you make about what will happen to the leaf disks in beaker B? Let's see.

If we set a timer, we might note the following data for beaker B:

Without plants, humans and animals would have less fresh air to breathe. Through the process of photosynthesis, plants release oxygen back into the atmosphere.  Plants are also important because they provide habitats for wildlife and humans.
