Prоducers, Cоnsumers, & Fоod Webs Using а pаint progrаm, hand drawing and scanning, or the site bubble.us, create an organism food web (NOT a food chain) with the following parameters. You food web should have 4 trophic levels (feeding levels). Each tropic level should be a different color (4 colors used). Include a key (like the one below) on your food web explaining the colors used for each level: (you can export your bubbl.us food web to word or paint program to add the key) Producer: color Primary Consumer: color? Secondary Consumer: color? Tertiary Consumer: color? Note you are asked to produce a “WEB” and not a chain meaning you will have to have specified multiple organisms in each level and multiple connections. Name your document with your last name and food web in the title (e.g. "Gordon food web.docx"). Upload your document here.

Enzymes: Lаctаid® is the cоmmerciаl name fоr the enzyme beta-galactоsidase which breaks down lactose (milk sugar) as shown in the following reaction: For this experiment, we mixed Lactaid® (the commercial name for the enzyme beta-galactosidase with lactose (milk sugar) and monitored glucose concentration in one tube containing milk and, in another tube, containing water. We used four different temperatures and obtained these results shown in the table. The levels of glucose was measured and recorded at 0 minutes then at 10 minutes. The results for the 10 minute reading are shown in the table below. Temperature (Lactaid® + lactose) (Lactaid® + water) 4oC 50 mg/dL 0 mg /dL 20oC 300 mg/dL 0 mg /dL 38oC 2000 mg/dL 100 mg/dL 99oC 0 mg/dL 0 mg/dL 1. At what temperature Lactaid® showed the greatest activity? Why? [question1] 2. What happen to the enzyme when you put it at extreme temperatures? [question2] 3. What is the dependent variable in the scenario above? [question3]
