Document Summary
In the same way that humans experience sunburn from too much sun exposure, so do plants. Excessive uv may damage or destroy plant protein and dna, killing the plant: plants and animals interact with their abiotic environment. 2. 2 ecosystems are not isolated from one another. One ecosystem blends into the next through a transitional region, an ecotone, which contains many species common to the two adjacent systems. 2. 3 an ecotone may create a unique habitat with specialized species not found in either of the ecosystems bordering it. The structure of ecosystems: feeding relationships, trophic categories, producers create organic molecules proteins, lipids and carbohydrates- by capturing light energy and combining the captured energy with inorganic molecules. 2. 4 the producers in all major ecosystems are green plants: consumers feed on producers and would not exist without producers. Omnivores are both herbivorous and carnivorous: detritus feeders and decomposers.
