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.
