Make a claim or observation about dead zones and nitrogen input in the Chesapeake Bay that is supported by the data in these figures. There is no single right answer to this question--any additional information that you can get from these figures counts! Note: Your observation should be more than stating the correlation (or lack of correlation) between the two variables.

+++ NA b. Macroinvertebrates-invertebrates that you can see without magnification-are indicator species often surveyed when assessing aquatic ecosystems. The following data table and graph represent macroinvertebrates sampled in two different streams, Stream A and Stream B. Using the data, develop a claim about the overall and relative water quality of the streams and support your claim with at least two pieces of evidence for each stream. Claim: Evidence: Total Biomass (g) Macroinvertebrate Species Name Mayfly nymph Caddis fly larva Freshwater shrimp Water louse Bloodworm Sludge worm 120 100 80 60 40 20 0 Pollution Tolerance Intolerant Moderately intolerant Moderately intolerant Moderately tolerant Moderately tolerant Tolerant Total biomass in sample (g) Stream A Stream B 0 0 Macroinvertebrate Biomass Comparison 4 30 70 34 10 2 G Mayfly Caddis fly Freshwater Water Bloodworm Sludge nymph larva shrimp louse worm Stream A Stream B 1 4 45 100
Can someone please help me with this assignment Create a diagram of the carbon cycle or the nitrogen cycle. You may use the draw function, or draw on paper and insert a photo of your diagram, or insert text boxes and arrows. Be sure to label the reservoirs (text boxes) and the flows (arrows) between reservoirs. thank you

Are the below statements true or false (correct or wrong)? You have briefly to motivate your answer using graphs and/or arguments. a) A specific forest area is discovered to be an important habitat for a certain variety of snakes. Thus, the optimal timber rotation time should be extended. b) Assume a mine extracting both copper and silver. If the price of copper falls and the mine managers decides to increase the production of silver, silver then represents a socalled by-product. c) A rise in global demand for copper will shorten the reserve life of a given copper mining operation. d) If a farm grows two different crops and the price of one of the crops increases, the production mix will shift towards reduced production of the crop that has become more expensive.
Pond A Pond B at the Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. True Falce For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. If Pond C is cooled to 10°C and the Stripey-Orange Clownfish die, then 10°C must be below the Stripey-Orange Clownfish's range of tolerance for temperature. △ 英拼

Answer All 3 parts
You visit a medium-sized Caribbean island and identify 4 species of anole lizard. Consider the 3 possible scenarios below. You return to the island a number of years after each of these scenarios. Explain which outcome below (i to iii) you expect for each scenario and briefly justify your prediction. 3-4 sentences for each scenario. (i) An increase in the number of anole species (ii) A decrease in the number of anole species (iii) No change in the number of anole species A) Scenario A: Scenario A: A new virus is introduced, which causes all the anoles to become colour blind. B) Scenario B: An earthquake separates the island into two islands. C) Scenario C: An invasive herbivorous insect species is introduced to the island, which devastates many plant species and causes the habitat to become much less complex.
PLEASE ANSWER A AND B As we know, energy is lost moving from one trophic level to the next (total energy moved from one trophic level to the next is usually estimated at 10%). The total loss is known as trophic efficiency. Trophic efficiency is made of 3 parts (3 places where energy is lost). You need to pick TWO of the three individual efficiencies that make up the overall trophic efficiency and for EACH, tell me: a. What do we call this part of trophic efficiency? b. How is energy lost in this part of trophic efficiency? c. We discussed characteristics of an organism or environment that made it more or less efficient in certain parts of trophic efficiency (we did not use this one in class, but for instance, endoparasites have a higher xxxxxxx efficiency than ectoparasites). Tell me what characteristics of an organism/ecosystem (other than the example above) would make it more or less efficient for this part of Trophic efficiency. (Make sure to say what characteristics makes it…

ANSWER THE FOLLOWING: If you are to engage into aquaculture, how will you do it considering your current location and available resources. What species, level of management and culture system will you consider? (imagine your location is Philippines) On the otherhand, if all resources are available and favorable, what brackishwater and marine species will you grow/culture? Discuss your criteria of considering these species. Describe the level of management and culture system that you will employ.
