On Column A write the common name of the subject specimen, then use a dash before writing the Scientific Name (must be Italicized), then use parenthesis in identifying its Heterotrophic Nutrition Mode. 3. Note that specimen (plant species) must be endemic, if not at least found in the Philippines.

Group of answer choices Eutrophication often starts with stimulating algal growth [ Choose ] TRUE FALSE Eutrophication results in loss of dissolved oxygen from the process of photosynthesis [ Choose ] TRUE FALSE It is the decomposition of algae after algal blooms that lead to bacterial growth causing a loss of oxygen [ Choose ] TRUE FALSE Eutrophication is a natural process and can occur in the absence of fertilizers [ Choose ] TRUE FALSEIn not more than 200 words or 5 sentences, answer or explain the following situation. In a seagrass ecosystem, nutrients restrict primary production under low nutrient (oligotrophic) conditions, while light becomes the limiting factor under high nutrient (eutrophic) conditions. Discuss how this happens with respect to the three primary producers (seagrass, macroalgae, phytoplankton) as the condition changes from oligotrophic to eutrophic.

- Q4.16. Your colleague designed a common garden experiment to determine if moisture level influences competition between a native alga and an exotic alga. The design includes four plot types: wet with native only, wet with exotic only, wet with both algae, and dry with both algae. The results are below. Plot Native alga Wet: native only Grew well Wet: exotic only n/a Exotic alga n/a Grew well Wet: both algae Grew well Dry: both algae Went extinct Grew well Went extinct You note that his experimental design is incomplete and, as a result, he cannot support one of the following conclusions. Which conclusion is NOT supported? The native alga's fundamental niche includes wet habitats. The exotic alga's fundamental niche includes wet abitats. The exotic alga competitively excludes the native alga in dry habitats. The native alga competitively excludes the exotic alga in wet habitats.Refer to the image: Discuss the succession of decomposers in your setups and explain the role of decomposers in the degradation of plant material. *The decomposing material is only the scraps of the plants, soil is not added.*Give answer to all parts? 1. Why might a soil bacteria (Azotobacter) have the ability to fluoresce? How does fluorescence differ from being pigmented. 2. What are the means by which soil can be depleted of useable forms of nitrogen?
- Explain what relative humidity is and provide 3 factors that cause it to vary in different areas.on 4 pts Symbiotic relationships with Nitrogen-fixing Bacteria: Rhizobium bacteria normally inhabit the soil. Suggest why nodules are found on the stems of Sesbania? The roots of the Sesbania are often underwater or in flooded soils that do not contain much N2. Bacteria live best above the ground. Sesbania only use the nitrogen in the upper portion of the plant so they do not need to make nodules on their roots. Bacteria will drown under water.

The DO level of bottle #1 was recorded immediately after the algae was collected, the DO level of bottle #2 was recorded after sitting for 20 hours wrapped in tin-foil, and the DO level of bottle #3 was recorded after sitting for 20 hours under a lamp. A heat sink was placed over all of the bottles to ensure that temperature did not have an effect on the results. The following data was collected: Bottle Number D.O. Level 8 #1 #2 1 #3 6 4.
