CTAHR learning trip
I really like the CTAR learning trip it was a great experience. I had so much fun working and learning about the place. I learned a lot on things like, how some plants work and how there environment can help them grow. I enjoyed working and giving back to the land and taking care of it because it takes care of me. At the CTAHR I was grateful to learn so much knowledge from Dr. Radavich. Some of my biggest take aways were, how healthy soil is very important to grow crops, and how organic nutrients make healthy crops and delicious foods. Its a great thing to know and practice the old ways of our ancestors.

Food Journal Results
in the early month of November my class was asked to log down all of the foods we ate everyday. This taught us how our responsibilities are important. It left us facing the challenge of how much effort we were really able to look into your self. To see what we as a person are putting into your bodies. We also answered a few questions, "Is it processed?," "Is it organic?," and "Is it locally sourced?." After I looked at my data I realized that over 19% of the foods that I eat are locally sourced, and organic. Looking at other classmates data on their food journals, I noticed that many don't eat local sourced or organic. This showed me that its harder for people to eat local sourced or organic foods.

Carbon Cycles
Definition: The series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
Steps of the Cycle
First the carbon enters the atmosphere as carbon dioxide from respiration and combustion. Then the carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis. The animals then feeds on the plant passing the carbon compounds along the food chain. Most of the carbon then is consumed and exhaled as carbon dioxide formed during respiration. The animals and plants eventually die.
The dead organisms are eaten by decomposers and the carbon in the bodies is then returned to the atmosphere as carbon dioxide. In some conditions decomposition is blocked. The plant and animal material may then be available as fossil fuel in the future for combustion.

Nitrogen Cycles
Definition: the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition. Steps to the Cycle Nitrogen is essential for the formation of amino acids in proteins. The nitrogen cycle is a model that explains how nitrogen is recycled. About 78% of the air is nitrogen. Nitrogen is so unreactive, it can't be used directly by plants to make protein. Nitrates contain nitrogen and Nitrates are soluble in water, so plants are able to absorb them from the soil through their roots. This is how nitrogen compounds can get into plants.Once in plants, the nitrates are used to make proteins for growth. When animals feed, nitrogen compounds such as proteins are passed along the food chain or food web. When animals and plants die, their nitrogen compounds are broken down by soil bacteria, fungi and other decomposers. In this way, nitrogen compounds are returned to the soil, where they may be absorbed by plants again. |
Oxygen Cycle
Definition: Then oxygen cycle is the biogeochemical cycle of oxygen within its four main reservoirs: the atmosphere, the total content of biological matter within the biosphere, the hydrosphere.
Steps to the Cycle
It starts of with plants and photosynthesis. During the day, the plants take energy from the sun, carbon dioxide from the air, and water from the soil to make their food. Their food is simple just glucose. This process is called photosynthesis. Oxygen is released into the air as a byproduct of photosynthesis. During the night, plants take in oxygen and release carbon dioxide, to maintain their metabolism. Which is why it is not a good idea to sleep under trees at night.The oxygen that is released by plants is used by humans, animals, and other organisms for respiration.

Loops
Positive Feedback and Negative Feedback Loops
What is a Positive Feedback Loop:
A positive feedback loop is when in nature the product of a reaction leads to an increase in that reaction. If we look at a system in homeostasis, a positive feedback loop moves a system further away from the target of equilibrium. It does this by amplifying the effects of a product or event and occurs when something needs to happen quickly.
Example: This is our first example of a positive biological feedback loop. If we look at an apple tree, with many apples, seemingly overnight they all go from unripe to ripe to overripe.
What is a Negative Feedback Loop:
A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. A negative feedback loop brings a system closer to a target of stability. Negative feedback loops are responsible for the stabilization of a system. To ensure the maintenance of a steady. The response of the regulating mechanism is opposite to the output of the event.
Example: Temperature regulation in humans occurs constantly. The normal human body temperature is around 98.6°F. When body temperature rises above this, two things kick in the body begins to sweat, and vasodilation occurs to allow more of the blood surface area to be exposed to the cooler external environment. As the cold sweats, it causes evaporative cooling, while the blood vessels cause convective cooling. Normal temperature is then regained. Should these cooling mechanisms continue, the body will become cold.

Food Security
What is Food Security?
Definition: The state of having reliable access to a sufficient quantity of affordable, nutritious food.
Food security is also the "availability at all times of adequate, nourishing, diverse, balanced and moderate world food supplies of basic foodstuffs to sustain a steady expansion of food consumption and to offset fluctuations in production and prices". Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life
