Soil: Wet
All day long, it has been raining on and off. The soil is extremely damp while the trees, grass, and flowers are all looking extremely green. The taller flowers along the side of the house have started to bloom, just enough to see the color inside through slits of the sepal. In my area, there is a very large biodiversity of flowers. Just naming the ones I know, there are tulips, and more natural to the area, lupine. These biotic organisms however must compete each other for the limited space. This intraspecific competition determines the population of each different flower species. During my last observation, there were dandelions coving areas of the yard. Now however, after there has been so much rain and no sun they are all wilted and dead. There are no insects out since the weather is very cold, but with all the rain there are worms coming out from inside the soil in search of water. This is also attracting a great number of birds. Even as the rain pours down, magpies occasionally fly down but mainly, robins have been preying on worms. This is the first time of the year I have seen any robins. The aspen tree's leaves have continues to grow, while the pine trees have only become more green with all of the rain.

Good job incorporating competition as well as all of the changes that have occurred with the brief stint of sun, followed by the rain. As you talked about the changes that you made, you made connections how quickly a lack of survival needs (for the dandelions, sun and drier conditions) can influence the success of certain organisms. Look into talking more regarding the interdependence among species in your area. How do they rely on each other for success?
