1

Rats that are poisoned by Warfarin were able to survive and pass on their genes to their offspring while the Warfarin resistant rats died.

1

1

Natural selection simply put is?

1

Peppered moths were affected by pollution which led to an increase in dark colored moths and a decrease in the light colored moths. What type of selection is exhibited?

1

In many bird species, males are larger and flashier than females. This occurs because females select those males.

1

❌ occurs when a population size is severely reduced. When a small group of individuals move to a new area branching out from the original population this is called the ❌. When alleles move between populations you have ❌.

Bottleneck

founder effect

gene flow

1

When genes cannot flow (reproduction cannot happen) between two populations because they have become so different this is called?

1

Types of Reproductive isolation:
Timing of reproduction differs in ❌ isolation
Size or shape of an individuals reproductive parts prevent it from mating in ❌ isolation
Differences in behavior causes ❌ isolation
When gametes meet up but are unable to form a zygote ❌ occurs.
When individuals can produce offspring but those offspring cannot produce functional gametes ❌ occurs

Temporal

Mechanical

Behavioral

gamete incompatibility

Hybrid sterility

1

What is a population?

1

What type of population size estimation is shown in the picture?

1

Which picture represents random distribution?

1

Which image represents clumped distribution?

1

What is the per capita growth rate (r) of a shrew population if the birth rate is .4 and the death rate is .1?

1

What is the size of a shrew population after one month if the starting shrew population is 300 shrews and the per capita growth (r) is 0.3?

1

❌ curves, death rate is high early in life. ❌ curves death rate for the population is fairly constant. ❌ curves; death occurs later in life.

Type I

1

When did the shrew population reach carrying capacity?

1

Which population has the highest percentage of births compared to the rest of their population?

1

In the United States are their more women or men above 60?

1

Density independent limiting factors include forest fires, tornadoes and floods.

1

Select the following reasons carrying capacity could be reached.

1

Species interactions:
A bird nesting in a tree is an example of ❌. An insect pollinating a plant is an example of ❌. Roundworms living in a dog's intestines is an example of ❌. Predation occuring between a lynx and hare is an example of ❌.

1

When a barren habitat such as a new volcanic island begins to colonize these individuals arrive first?

1

In secondary succession, pioneer species colonize a barren habitat such as a new volcanic island.

1

Kudzu, a type of vine introduced to the United States grows extremely fast in the southeast and now blankets almost everything. Kudzu is a type of?

1

In a food web, grass is usually considered the _________________________.

1

In this energy pyramid which trophic level would be considered the heterotroph/primary consumer.

1

In an energy pyramid to describe feeding relationships within an ecosystem as you go up the pyramid the amount of energy increases.

1

Which of the following elements cycle through ecosystems?

1

What type of consumer is the fox?

1

Which organism is the primary producer?
