My Response
Overall, I enjoyed doing this project with my plot and I learned many things about it. First of all, I learned about all of the different kinds of fungi my plot had. My plot is in the far back of my backyard, and I have been back there before, but I never saw some of the amazing types of fungi I found while tramping around doing plot assignments. The species ranged from small, white shelf fungi to large, brown bracket fungi. Another thing I learned was how many different organisms dwell in my plot. I found many different species of the typical omnivores and herbivores, but I was introduced to detritivores through science class and found many decomposers, too. A third thing I learned was how easily my plot can become trashed up. It's a pretty secluded area, so I was surprised at how much trash had gotten there. This reminds me not to litter because of its uncleanliness not only to the environment but also to the eye. I also learned how many of the trees on my plot change brilliant colors of red orange, and yellow. I knew that they changed, but I was surprised at how the colors were so vivid. Lastly, I learned about how all of the organisms living there are related in terms of being in a general food web. I found out how energy flows from the sun all the way to a fox or deer living on my plot, and how this system is a constant cycle happening all the time. This knowledge I've learned has caused me to be more aware of God's creation around me and increases my concern for the earth's well-being, especially the things that I personally am doing to harm my plot and places similar to it even though it may not be directly. This project will also cause me to go outside more and observe nature more carefully.

Seasonal Changes - Tree Characteristics
The tree I chose to take leaves from is a red maple tree. It's approximately 35 feet tall, is pretty narrow, and is relatively young for a tree, about 20 years. An interesting fact is that one of its branches changes directly to red even before the other branches turn to yellow. Its bark is brownish gray and is overall smooth just with some rough sections (for example, the picture), and the leaves are a yellowish green in the summertime turning to brilliant shades of red and yellow in the fall.

Producers and Consumers
I saw many different species of plants and animals in my plot. Here are a few examples along with their status as a producer or consumer:
I. Consumers
1) Herbivores - deer, rabbits, bumblebees, moths, butterflies, fruit flies, and squirrels.
2) Omnivores - mosquitoes, bluejays, cardinals, tree frogs, ladybugs, toads, and chickadees.
3) Detritivores - slugs and worms.
4) Decomposers - shelf fungi, mushrooms, and bracket fungi.
II. Producers - pine tree, maple tree, poisen ivy, grass, thornbush, crab apple tree, moss, apple tree, pear tree, dandelions, and a sassafrass tree.

Plot Community
My plot's inhabitants interact with eachother in many different ways. Competition is seen through squirrels fighting for nuts and other food and also through the birds fighting for the proper nesting tree or worms and seeds. Predation is seen when birds hunt for worms, and also through spiders building webs and catching flies. I can see mutual symbiosis through squirrels, rabbits, and other mammals producing carbon dioxide for plants, and in return, the plants produce oxygen for the breathing animals. Also, the ants and aphids dwelling in my plot have a mutual relationship because the aphids produce a sugar-honeydew substance pleasing to the ants, and in return, the ants protects the aphids from unwanted predators. There are also many ways I see commensalism in my plot. One example is how birds make nests in trees. The tree helps the bird by giving it shelter, but it doesn't benefit nor become sick from the bird. Another example would be how moss grows on trees. The moss benefits from proper sunlight and nutrients from the tree, but it neither helps nor harms the tree as long as it doesn't become too heavy. There are also examples of parasitism. One example would be mosquitoes. They benefit when they suck an animal's (or human's) blood, but they cause irritation and can even transmit diseases. Another example would be ticks. They cling to their host and feed on them, so the host, such as a blade of grass, gets weaker and weaker.

My Plot is An Ecosystem
My plot contains many species, populations, and communities in the area. I've seen many species of plants and animals such as squirrels, rabbits, deer, birds (like chickadees), maple trees, pine trees, poison ivy, mosquitoes, and flies. The populations dwelling there would be a pack of squirrels, a pack of rabbits, a herd of deer, a flock of chickadees, many groves of trees, groups of poison ive, swarms of mosqitoes, and swarms of flies. I've noticed the inhabitants interacting with eachother by seeing squirrels run up trees and build their homes their along with birds and their nests. Also, I see deer eating apples that grow on some of the apple trees in the plot. Another interaction is how the flies and mosqitoes irritate the deer and rabbits when they land on them. My plot is in the temperate deciduous climate zone which, overall, makes up a tiny portion of the biosphere.
