My Response:

I found your presentation to be rather intriguing learning new ideals such as statistics and facts about fossil fuels. I felt that the images fit perfectly with the topic at hand and some were quite amusing. Overall you did well laying out the presentation but i felt that there was little explanation as to what a greenhouse gas was and what it causes. Other than that, your presentation was great.

My Response:
The picture of the destroyed lungs of the earth really stood out to me.  People don't really seem to be very interested in the future of our world as they continue to cut down our sources of oxygen and destroy our future.  Your presentation connects to mine in virtually all aspects as we explored the same topic.  What do you mean by ypur possible solutions?  They weren't explained very well and cause some questions to arise.  This student has included a specific list of the sources from which she got her information.

My Response:
Your topic about global warming made me think about what we can do to stop it. By looking at your pictures of things caused by global warming, like deforestation, melting icebergs, and more, I can tell that global warming is a big issue. Your topic ties in with mine, deforestation, because deforestation contributes to climate disruption the Earth. A question I have is how does global cause natural disasters to become more frequent? Overall, your presentation made me aware of how global warming is affecting the environment negatively.

My Response:
The first thing that caught my eye in your presentation was all of the cut down trees in a pile. It's hard to believe that so many trees are cut down just for farming or expansion. I liked how your presentation had lots of pictures of deforestation, especially the picture with "the lungs of earth", because it really shows how deforestation is not good for the environment in many ways. Like my presentation, yours stresses the problem of how deforestation is affecting animals greatly. You could have elaborated more on the causes of deforestation, so we can begin to brainstorm ideas to put an end to deforestation. Overall, your presentation can make one think about what we can do about deforestation and how we can stop it.

Plant Status Update #5

     Our plants are still very healthy and growing well. We saw white flowers on our beans and these flowers are what will help our plants reproduce. Our beans could increase their numbers as pollinators, such as bees, come around and pollinate the flowers and ultimately fertilizing them. The flowers then grow into beans and the bean life cycle starts again with another bean plant. However, beans that do not survive and fall into the soil can be used to grow more bean plants.
     There are many factors that would limit the number of beans that can grow in each garden box. Some include soil texture, pollinators, space, and the amount of supplied water. If there are too many beans in one area, then they will not have the necessities viable for them to survive. Therefore, I believe the carrying capacity of one garden box for Phaseolus vulgaris is about one hundred seventy-five plants. I believe there is room for this amount of plants but there would be a lack of resources which would make the amount of plants to about two hundred.

Plant Update 5

     Our plants are bright and healthy.  They are continuing to grow bigger each day.  We recently started seeing little white flowers on our beans.  These flowers are what will help our plants reproduce. Our beans could increase their numbers as bees come around and help fertilize the flowers by spreading the pollen.  The flowers would then grow into the actual beans.  As the beans sit there for a while they dry out and fall off the plant, if not picked, dropping into the soil to grow up next year increasing the bean plant numbers.
     There are many factors that would limit the number of beans that can grow in each garden box though.  These factors may include soil availability, water availability, space availability, and bee population for fertilization.  If there are too many beans in a enclosed areas they will not have enogh soil to stabilize in and will not be able to collect as much sunlight for photosynthesis making it hard for them to survive.  On that note, I believe the carrying capacity of one garden box for Phaseolus vulgaris is three hundred and twenty-five plants.  I believe there is room for this many if not more.  However, I believe the main limitation would be lack of resources causing the carrying capacity to be somewhere around three hundred and twenty-five.

Plant Update #5

New anatomical structures on our plants include small white flowers and more leaves.  I think that the small flowers will perform photosynthesis, which will provide our plants with more energy.  Our plants can increase their numbers by getting more water and reproducing seeds, which would lead to more of our plants growing.  Some factors that limit the number of bean plants that could grow in each garden box are other plants and weeds competing for water and energy from the sun, and organisms living within the garden. Some of the organisms living in the garden are eating the leaves of our plants.  I think that the carrying capacity in one garden box for Phaseolus vulgaris is 50 plants.  I think this because there are also other weeds and plants growing in the garden, and there is probably no room for any more than 50 phaseolus vulgaris plants.

Plant Update #4

Some abiotic factors (non-living factors) that our bean plants depend on are water, soil, temperature, and sunlight.  Some biotic factors (living factors) are insects and birds. Competition is when organisms use the same limited resources or nutrients.  Our plant is competing with other plants around it for sunlight. We can infer that the plant that is the tallest-growing is getting the most sunlight.
Sometimes, "winners" and "losers"are determined by what organism has the longest life-span.  Other times, it depends on which organism is healthier, and it doesn't necessarily depend on which lives the longest.  There is not always a clear cut "winner" and "loser" to this struggle.  Sometimes, the plants get equal amounts of water and sunlight, and there is no conflict between unequal distribution.
Other types of interaction I saw was the predation. Predation is when one organism eats another.  Parasitism is when one organism depends or lives in another organism, and the organism is harmed.  An example of predation and parasitism is on our seed plant is the insects living on it.  Little by little, the insects are eating the leaves of our bean plant, which is harming it, and the bean plant is also not benefitted in any way.
There is a lot of evidence that shows that succession is occurring in the garden ecosystem.  When we first planted our seed in the garden, there was nothing but dirt and soil.  Now, our plants are there as well as other grasses and plants, such a buckwheat.  This shows that succession has occurred.  Primary succession begins at a place without any soil.  Secondary succession begins at a place that already has soil and was once home to another organism.  In this particular situation, I believe that it is secondary succession, because there was already soil and other organisms living in the garden.


Plant Update 4

     Our beans depend on abiotic factors like water availability, soil fertilization, and temperature for its survival. More abiotic factors are amount of sunlight and geographical features. Competition, for example other plants growing around them, and predators, for example birds and insects are biotic factors that affect our plants. Competition is when two or more species in an ecosystem need to use the same resource at the same place and time.
     Our plants are engaged in competition for sunlight and water. We can tell this because the are growing in the direction of the sun. The competition is the other plants that have grown up around our bean plants. They also compete for water by reaching their roots down as far as they can.
     "Winners" and "losers" are partially determined by what plants live and what plants die. Sometimes it is hard to tell  who the "winner" or "loser" is. Not being able to see the roots and tell how much water different plants are getting makes it difficult to determine who "wins" or "loses" the struggle.
     Our plants are involved with preditation as well. Our beans are attacked by predators, while they "prey" on sunlight. Predators are organisms that kill and eat other organisms for food. Prey are the organisms being eaten. The plants are also involved in symbiosis. Specifically they are involved in mutualism, in which two organisms use each other and both benefit. The plants provide nectar for bees and in return the bees fertilize our plant's flowers.
     When we first ventured into the garden there were no plants growing in the beds we planted our beans in. There was chopped down plants suggesting that there had been plants there before. This would mean that something like secondary succession occured as our beans grew and other plants grew up around them.
