Identify the position on the graph that gives the carrying capacity of the population.
dolphi86 [110]

The carrying capacity of any individual biological species is the maximum size of the population which can sustain indefinitely in that environment provided the necessary requirements like food, water and other environmental conditions are available.

The carrying capacity in the graph is the point on the graph where the line of population is horizontal. The graph has the population in y-axis and time period on x-axis. Alternatively if in the carrying capacity graph the line becomes parallel to x axis then it gives the carrying capacity. Here, at the point 2000 on y-axis and starting from 15 months in x-axis is the point of carrying capacity is marked with red horizontal line and green border in the image attached.

Describe the impact of a waterborne pollutant on an aquatic community. write a 100-word report on how that pollutant affected aq
Rufina [12.5K]
A waterborne pollutant can have different effects on aquatic life depending on the nature of the pollutant. A pollutant at lower levels can have minimal or no effect on aquatic life. However, when the concentrations of the pollutant are high, the population of aquatic organisms can be greatly reduced. There are also times when pollutants at lower concentrations cause significant damage. An organism can consume another organism that has absorbed small amounts of the pollutant. As the consumer takes in more of the contaminated organism, the pollutant is magnified in the body of the consumer resulting in lethal concentrations. This is called biomagnification.

Which process or processes are responsible for the series of ice ages that occurred during the cenozoic era?
jonny [76]

Answer:

Glaciation and the Antarctic Circumpolar current

Explanation:

As the supercontinents continued to separate, cold water was easily transported around the globe through the Antarctic Circumpolar current. This assisted periodic glaciation during the Cenozoic Era, leading to a series of ice ages.
