Biology Question! Water wisteria is an aquatic plant that is easy to care for and reproduces very quickly. A small man-made pond of 350 L contains 78 water wisteria plants. 15 new plants are introduced daily to the pond, while 50 plants are taken out once a week to be sold at local pet shops. What is the overall population change in a two-week period? Express your answer rounded to the nearest whole number. What is the population density of water wisteria at the beginning? Express your answer as a value between 0 and 1 rounded to two decimal places.

A researcher decides to try to incorporate stochasticity by changing carrying capacity (K) in the logistic model over time. This would be best considered а. Noise O b. Demographic heterogeneity С. This is not stochasticity O d. Demographic stochasticity O e. Environmental stochasticity
Question 3 Which of the following statements is consistent with the abundance-center hypothesis? (Choose all correct answers). (Lech Species decrease in abundance towards the range periphery, as conditions become less optimal for growth and reproduction. Towards the range periphery, birth rates far exceed death rates, compared to areas at the range center. Areas at the center of the species' range have higher abundance due to high immigration rates of individuals from the range periphery Areas at the center of the range are more likely to be source populations, whereas areas at the range edge are more likely to represent sink populations. Within a species distribution, individuals are most abundant towards the range center, where conditions for growth and reproduction are optimal.

Question 4 How would fire suppression in western states impact habitat diversity? O habitat diversity would increase because fire destruction is being limited O habitat diversity would increase because fire kills resistant species O habitat diversity would decrease because less fire disturbance means higher levels of colonizer species O habitat diversity would decrease because the forest would all be at the same level of succession A Moving to another question will save this response. ts fe 12 米 esc 23 24 & 4. 8 Q W E tab F G H caps lock A B # M と不

A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) O Yes, this is a suitable habitat. The birth rate is higher than the death rate. D No, this is not a suitable habitat. The birth rate is much lower than the death rate. 589 -358 a 0.155 O 0.845 Which of the following is true of a population approaching its carrying capacity? O The population's rate of increase approaches zero. ロロロロロ □
