Analysis of the Garden and Plants To survive, our plants depend on water, sunlight, temperature, animals, etc. Biotic factors such as animals and other animals affect my plant because they kill the plant. For instance, animals can eat the plant and other plants can take the water that the plant needs to survive. Our plants compete daily against the plants in the garden for water and sunlight. In this struggle, it is clear to see the "winners" simply by observing which plant grows more and which one dies. However, it's sometimes hard to see if both plants keep growing. Our plants are also involved in predation with animals because herbivores and omnivores use them as an energy source. On the other hand, plants do not gain anything from this because they are eaten. Plants growing is evidence that there is succession in the garden. This type of succession is secondary because there was already soil. -Natalie Martinez
Cycles and Our Plants This week, I noticed that our plants have grown a lot and are a lot taller. I also observed that they are a lot bigger compared to other plants. Our plants play a big role in the water cycle due to the fact that they absorb the water in their roots and help it return back into the atmosphere when it evaporates from their leaves. This, transpiration, relates to my observations because the plants absorbing the water helped them grow. In the carbon cycle, our plants participate in photosynthesis and respiration. This cycle affected my plants because it keeps them alive. To add on, in the nitrogen cycle, our plants use nitrogen to make proteins, which can then be consumed my animals. The plants' nitrogen uptake keeps them alive. -By Natalie Martinez
