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.

Fill in blanks

D.A change in average temperature is a density-dependent factor because fewer organisms can acclimate to variations in temperature. Base your answers to questlons 14-16 on the Information below and on your knowledge of blology. Unless actions are taken to slow the decline of domesticated honeybees and augment [increase] their populations with wild bees, many fruits and vegetables may disappear from the food supply, said Claire Kremen, a conservation biologist at Princeton University in New Jersey... The honeybee decline, which is affecting domesticated and wild bee populations around the world, is mostly the result of diseases spread as a result of mites and other parasites as well as the spraying of crops with pesticides, scientists say. Source: "Bee Declines May Spell End of Some Fruits, Vegetables," National Geographic News, October 5, 2005 14. The decrease in the honeybee population is partly due to A. the use of pesticides B. the use of fertilizers C. a decrease in prey D. a…

22. A ______________ is the combination of conditions and resources that allow a species to exist, grow, and reproduce in the presence of other species such as competitors and predators.   fundamental niche ecological trade-off niche complementarity realized niche

A sudden natural catastrophe resulting in massive die-offs would be categorized as a density-________ limiting factor. Select one: Autonomous Reliant Dependent Independent

Define the niche concept. How does the “realized niche” of a popu-lation differ from its “fundamental niche”? How does the concept of niche differ from the concept of guild?

In a 50 square mile section of forest, there are some cut patches of forest where the trees have been removed and some patches of forest that have been left uncut. Birds are nesting in both cut and uncut forest patches. Beginning with the first step, place the steps in sequence for an investigation of the nesting birds using the scientific method. First step of investigation End of investigation Answer Bank Determine whether more birds nest in cut or uncut forest patches and share this conclusion with other researchers. Compare the data collected concerning nests from cut and uncut patches of forest. Observe birds nesting in cut patches and uncut patches of forest. Identify several patches of cut forest and several patches of uncut forest and decide how to conduct nest counts in them. Count the number of nests found and record the data. Hypothesize that more birds nest in cut forest patches.
