According to Worldometers, in late November, 2018, the U.S. population was 327,726,061 and the world population was estimated at 7,666,602,725. Considering those numbers, do you think the United States is in a population crisis? Do we have enough land and resources to support a continuous increase in population? Should we, as a nation, concentrate on controlling our population or controlling resource use? Why, or why not?

I’m not quite sure which answer would describe the graph can you please help?

You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America.   Which of the following could be a possible factor for the increase in the grizzly population?     Loss of habitat     Reduction of resources     Increased industrialization     Higher birth rate over death rate

Carrying capacity is the maximum number of animals an environment can support. Looking atyour graph, what do you think the carrying capacity for deer might have been? Why?

Brachionus calyciflorus is a species of zooplankton (small animal or animal-like aquatic organisms) that feeds on algae. In an experiment, scientists set up five containers with equally sized populations of B. calyciflorus and provided different quantities of food to each population for several days. The graph shows the average daily growth rate for each of the five populations. EFFECTS OF FOOD QUANTITY ON POPULATION GROWTH RATE 0.5- --0.5+ -1.0+ -1.5- 0.2 0.4 0.8 1.6 3.2 Food Quantity (mg) A student claims that the population that was provided 0.4 mg of food will be larger than the population provided 0.8 mg of food. Based on the data in the graph, drag the appropriate text into the boxes to indicate whether you support or refute the claim and to provide the evidence that supports your answer. Population Growth Rate (percent per day)
