- What is the relationship of the two variables illustrated in the graph above?A biology student is investigating the claim that the temperature can be predicted by counting cricket chirps. He has collected data and comes up with the linear model T=39.2+0.233r, where T is the temperature in degrees Fahrenheit and r is the number of chirps per minute. Interpret the slope of the equation. The model predicts a decrease of 0.233 degrees for each increase of 1 chirp per minute. The model predicts a decrease of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 39.2 degrees for each increase of 1 chirp per minute. The model predicts an increase of 0.233 degrees for each increase of 1 chirp per minute.Consider the variables: A, B, C, D, E, F, G, and H. A and B, B and C, C and D are directly related while D and E, E and F, F and G, and G and H are inversely related. If an initial increase occurs in the value of A, the value of H will a. decrease b. increase c. stay the same d. cannot predict from the given information

O a. carrying capacity O b. plateau ability O c. log phase O d. lag phase (y-axis)Grasses are the dominant producers in the prairie ecosystem. Mice eat the grass seeds, snakes eat the mice, and hawks eat the snakes. The mass of a hawk is around 500 grams. In this ecosystem, how many hawks can be supported by 250,000 kilograms of producers? Recall that 1 kilogram is equivalent to 1,000 grams.Which of the following are variable terms in the discrete-time logistic model? ΔN Δt rmax,d t Nt K None of these
- A region of North America has a population of 65,000 deer in 2016. The deer are kept in check by a wolf population. The carrying capacity of this region allows for 82,000 deer. For this example, assume the rmax is 1.0. With this information, answer/calculate the following:[21-23] Suppose a species of frog has the option of three different prey items: crickets, cockroaches, and ants. Ants are the most abundant in the environment, with a relative abundance of 0.8. The relative abundance of cockroaches is 0.2, and the abundance of crickets is 0.1. A dietary study of frogs determines that crickets make up 50% of the diet of these amphibians, cockroaches are 40% of the diet, and ants are 10% of the diet. 21. What is the Manly-Chesson index of prey preference for crickets? Round to the nearest tenth. 22. What is the Manly-Chesson index of prey preference for ants? Round to the nearest hundredth. 23. The preference for ants is e. negative f. positive g. neutral.Based on these graphs, and assuming head raises of European finches helps watch for predators but also has a trade-off with eating, select the statements that these graphs support. Total head raises of entire flock per minute (a) 28 24 20 16 12 8 4 4 5 Flock size 0 1 2 3 6 Individual head raises per minute (b) 12 10 8 N T 0 1 2 3 4 5 6 Flock size Time to husk a seed (seconds) As the flock size increases, individuals have less access to food 1.8 1.6 1.4 1.2 1.0 1 C 01 2 3 4 5 6 Flock size O The larger the size of the flock, the smaller the fitness of each individual As the flock size increases, individuals are able to eat more quickly The graphs support the hypothesis that there is no tradeoff at the individual level between watching for predators and husking seeds When groups are larger, individuals can spend less time watching for predators, but as a group they have spend more. The graphs support the hypothesis that there is a tradeoff at the individual level between watching for…

The graph can be any style or format but must display a relationship between the independent (x axis) and dependent (y axis) variables.c. Both axis of the graph must be correctly labeled, including correct units, andrepresent the independent and dependent variables.d. The graph must contain a trendline with a trendline equation and R2 valueDippers (Cinclus cinclus) are small birds that can be found along fast-flowing streams in Europe and Asia. They feed on insect larvae, especially those of caddis flies (Trichoptera), which they catch by sticking their heads under water and turning over stones. Describe the relationship between the abundance of caddis fly larvae and dippers?Why, is caddis fly larva abundance expressed as ‘relative abundance’? using the data in Table 2Given the information provided in Box F, how much grasshopper (species iv) production can be expected if primary production is 256478 kj.m-2yr-1. Assume that all primary consumers get equal shares of primary production.
