To review:
The relative order of the given sites where lichens are grown, based on their distance from the large city center; other factors that might influence the prediction, and the two big factors that might affect these results.
Given:
The data related to lichens from five survey sites are tabulated as follows in Table 1 below.
Table 1: Number of lichen species and the number of tree branches (in percent) covered in lichen at five different sites.
Site number | Number of lichen species | Percent of tree branches covered in lichens |
1 | 5 | 38 |
2 | 1 | 2 |
3 | 3 | 15 |
4 | 8 | 75 |
5 | 13 | 100 |
Introduction:
A lichen is the combination of two organisms that exist together in a symbiotic relationship. A symbiotic relationship is the one in which two organisms live in a harmony without harming each other. In case of lichens, the

- U.S. coral reef ecosystems cover less than one percent of the Earth's surface yet are among the most diverse and productive communities on Earth. We rely on reef ecosystems for food, shelter, tourism, and recreation. Despite the importance of reefs, these ecosystems are in trouble. Scientists are working to understand the extent of and reasons for the decline of coral reefs and to provide managers with more effective ways to protect them. A. Think of the distributions of stony coral and how it seems to be the most prominent. A scientist wants to figure out if this has to do with the stony coral growing on multiple substrates. i. Identify a reasonable hypothesis that would help guide the scientist to their answer. ii. Identify the dependent variable in your proposed hypothesis. iii. Explain how the results of the experiment might be affected by other influences in the ecosystem. B. Use the map to identify the following: i. Identify the predominant locations where coral reefs are…arrow_forwardIf I find dead frogs in Australia infected with chytrid fungus, and in South America, and in North America, I could infer that chytrid fungus is related to global frog declines. ainductive reasoning bdeductive reasoningarrow_forwardA hypothetical protist, Protista biologica, can become inhabited by a bacterium. This bacterium receives nutrition from the protist host and produces a dangerous toxin to the host.

- ex. Locate any woodland or forest area close to your home. Create a 10 x 10 m quadrat once you've identified a suitable location. Markings can be made with a straw or a rope. List and count any fauna found at the locations (either inside or outside the quadrats). 1. How far should you record and observe any fauna encountered outside the quadrat? Why do you think it is not necessary to note the distance for faunal observation outside the quadrat?arrow_forwardSCIENTIFIC 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 2.3arrow_forwardWhich of these pairs is mismatched?a. tundra—permafrostb. savanna—Acacia treesc. prairie—epiphytesd. coniferous forest—evergreen treesarrow_forward
- According to the morphological species concept, would you classify benthics and limnetics as A) a single species B) separate species C) the species status is not clear according to this species concept. Explain in 2-3 sentences. (I think the answer is separate species, not sure how to explain this...)arrow_forwardChoose one named example (a plant, animal or fungal species) and provide a summary of the spatial distribution of that species. You need to to include the distribution of the individuals at various scales.

- For the the organisms Orchard Spider and Allies What is the geographic distribution of each species? Is it native or invasive? indicate where it is native and if it is not native, indicate where its native range is. Write a short description of each organisms’ life history (no more than three sentences for each one). Life history facts include diet, behavior, breeding, habitat etc. After reading about the life history of the three species you are focusing on it should be relatively simple to isolate what you find most interesting about them. Write a short description about what you find most interesting about all three species you are focusing on (no more than four sentences for each species).arrow_forwardIn a diagram, illustrate the dynamics of the benthic ecosystem particularly showing life habits of the benthos. Make the interactions in the benthic ecosystem explicit in your diagram.

Data: • in 6 Celsius temperature from 10 meal worm none shedded and none died • In 26 Celsius temperature 2 meal worms out of 10 shedded and 1 died having only 9 alive Please please Site your sources for the information you found and Avoid saying: GROW, PROVE, IN THIS EXPERIMENT Common problems with poorly written lab reports. • Use the abstract to introduce the report instead of to summarize. • Refer to the specimen by common name instead of by scientific name. • Refer to errors that may have occurred without discussing the evidence that those errors actually did occur Can you please please answer I really need it please at least try to answer it's very important please thank you I would really appreciate it if you could please try to answerarrow_forward
