A geologist is studying an ancient stack of rock layers. Most of the layers contain fossils of shallow marine creatures (clams,

Paul [167]

Answer: C. The environment changed suddenly from a shallow ocean setting to a river system.

Explanation:

The presence of the fossils of shallow oceanic creatures like corals points to the fact that the environment was a shallow ocean at some point. There is also a presence of a layer on top of that which points to a river system.

The fact that the oceanic fossils are beneath the river system layer means that the ocean came first and the river system layer came second. The environment must therefore have been a shallow ocean setting that changed into a river system.

2. Describe the growth of the hypothetical population shown in the graph,

ozzi

The growth of the population is described below.

<h3><u>Explanation</u>:</h3>

The population growth of the region is varying according to many factors like,

A. Members of the reproductive age group.

B. Availability of nutrition.

C. Mortality rate of the population.

Here the members of the reproductive age group are few. The population being small in a large area there is a high availability of nutrients.

So the growth rate of the population will be very high. This is called the log phase of the growth.

Then comes the lag phase of growth where the population is considerably big with a fight for food and shelter. The survival of the fittest is seen and the population still grows but slowly. This is the lag phase.

But with time, the population growth is stopped because the ecosystem has a particular carrying capacity which is the maximum number of population that the ecosystem can support. So beyond this, the population won't increase, and thereby the natality rate and the mortality rate becomes equal.
