EVOLUTION LINK The number of protonephridia in a planarian is related to the salinity of its environment. Planaria inhabiting slightly salty water develop fewer protonephridia than those inhabiting less salty water, but the number of protonephridia quickly increases when the concentration of salt in the environment is lower. How is this increase adaptive? Explain.
Whichaspects of the biology of zooxanthellae are controlled by their coral hosts?a.Their cell wall chemistryb.Their population growth rate when free-livingc.The release of photosynthetic products from their cellsd.The rate at which they absorb sugars from their hostse.Their mortality rate
WRITE ABOUT A THEME: ORGANIZATION As you read inthis chapter, fungi have long formed symbiotic associationswith plants and with algae. In a short essay (100–150 words),describe how these two types of associations may lead toemergent properties in biological communities.
This is marine biology 1. Classify the 2 types of primary producers: Diatoms/Dinoflagellates (domain? kingdom?) Macroalgae (domain? kingdom? phylum?) 2. Phytoplankton made of neither________________ 3. Draw a trophic pyramid and label the levels. Which trophic level has the least biomass?
How do pigments such as phycoerythrin in red algae and fucoxanthin inbrown algae benefit these autotrophic protists?a. The pigments provide camouflage, so herbivores cannot see thealgae.b. The pigments absorb blue-green underwater light and transfer theenergy to chlorophyll a for use in photosynthesis.c. The pigments attract aquatic animals that carry gametes betweenseaweeds.d. The pigments absorb UV light that would harm the photosyntheticapparatus.e. All of the above are correct.
Which group of Algae can follow any of three basic life cycles: haplontic, diplontic and haplo-diplontic? A. Green algae B. Diatomophyceae C. Phaeophyceae D. Red algae E. Cyanobacter
Mountain yellow-legged frogs live in the Sierra Nevada mountains.Their tadpoles mainly eat algae. One predator of adult frogs is a gartersnake, which is eaten by bullfrogs. Recently, a chytrid fungus haskilled many adult mountain yellow-legged frogs. How might thischange affect the algae, garter snakes, and bullfrogs?
What happened to the sea floor algae and plants? If fewer organisms are eating them, shouldn’t their numbers have increased? Why are they rare now?
Marine Biology a) Despite being so large, the ocean contributes to (more or less) primary production because it is__________, which means it doesn't have very many nutrients. Even so, _______________can survive her and absorb the few nutrients because they are____________. Small things have more_____________ b) cyanobacteria were the first to produce oxygen and form stromatolites made of ______________
You have discovered a new species aquatic protist that is a primary producer. It cannot swim on its own. It appears to be resistant to physical damage from wave action due to the presence of a glass-like wall. Which of the following organisms would this organism be most like? A) diatom B) dinoflagellate C) apicomplexan D) red alga
All of the rose-colored patches on the rock are actually encrusting coralline algae, which is a type of red algae or Rhodophyta. This algae deposits calcium carbonate in its cell walls, making it hard. 1. What type of organisms do you think eat this type of algae? 2. What role do you think this type of algae has in coral reefs and rocky shores? 3. Why do you think most red algae is typically found deeper in the ocean?
SCIENTIFIC INQUIRYINTERPRET THE DATA The feather moss Pleurozium schreberiharbors species of symbiotic nitrogen-fixing bacteria.Scientists studying this moss in northern forests found thatthe percentage of the ground surface “covered” by the mossincreased from about 5% in forests that burned 35 to 41 yearsago to about 70% in forests that burned 170 or more years ago.From mosses growing in these forests, they also obtained thefollowing data on nitrogen fixation: Age(years after fire) N fixation rate[kg N/(ha · yr)] 35 0.001 41 0.005 78 0.08 101 0.3 124 0.9 170 2.0 220 1.3 244 2.1 270 1.6 300 3.0 355 2.3
