Transect #2 Dave & Sophia
Variety Photo below
There are only three organisms at the top of the tube, and were all Arachnids.
The size ranged from .1mm to 2+mm. The most common organisms were Arthropoda (Insecta), which had segmented bodies with three pairs of legs. The smallest organisms belonged to the class Insecta, and the largest organisms were all Arachnids, with the exception of one fly, Diptera.
Arthropoda - Arachnid: 4 pairs of legs, cephalothorax, visible fangs, resembles a spider, largest organism with 2mm, 1/3 found.
Arthropoda - Arachnids: 4 pairs of legs, visible abdomen and cephalothorax separation, about 1mm long, 2/3 found in sample.
Arthropoda - Arachnid: 8 legs in four pairs, abdomen and cephalothroax, .25 mm length, 1/1 found.
Arthropoda - Insecta (Diperta?): 3 body segments, 6 legs, no visible mouth parts, compound eyes, two pairs of wings, about 1mm in length, 1/1 found.

Community: A biological community contains populations with different species that interact in specific areas. In our transect, the community is made up of the plants and animals that live there. Each of these populations live and interact there which allows them to have sustainability, as demonstrated in the food web.
Carrying Capacity Carrying capacity is the maximum number of individuals in a population that can be supported in a habitat over a sustained period of time. In transect #2, carrying capacity is demonstrated through each level of life, and occurs due to space, sunlight, proximity to water source, and plant life density.
Trophic Levels Trophic levels are energy rankings in the food chain. In transect #2, level 1 is occupied by primary producers (autotrophs: trees, grasses), Trophic level 2 is occupied by insects which are primary consumers and decomposers. Trophic level 3 feeds on insects and contains secondary consumers such as spiders, turtles, frogs, and fish. Trophic level 4 consists of tertiary consumers such as birds (finches and woodpeckers).
