Final Study guide==

Explain two out of the four ways in which biodiversity is important to ecosystems and humans. (Explain all four for extra credit)

Different spices help each other in the habitat - Making everything even in the habitat.

What are four ways populations can be predicte

Fertility rate Resources amiable Ratio Males---> Females Area size

Predict what might happen to the population of rabbits and coyotes if therabbits exceed the carrying capacity of the environment. Explain yourreasoning.

If the rabbits exceeded the carrying typicality, the coyote population will be very high. Then once the grasses and the food the rabbits eat disappears, so will the rabbits, from dieing or leaving that area, making the coyotes die or also leave the area.

Explain migration and emigration.

Migration: LEAVING a area Emigration: Going INTO a area

Explain how the meaning of Niche and Habitat differ.

Niche --> Organisms job in the habitat Habitat --> Where a Organism lives

Which of the following species has the highest reproductive potential?

Rabbit

Each of the following is an example of a parasite except

a cow in a pasture

Land that can be used to grow crops is called...

arable land

The study of human population patterns is called

demography

The number of wild horses per square kilometer in a prairie is the horse population's

density

the basic facilities and services that support a community is called

infrastructure

average number of years a person is likely to live

life expectancy

In which type of interaction between species does one species benefit by harming another species but not killing it?

parasitism

An example of a population would be all

red maple trees in a forest

The carrying capacity of an environment for a particular species at a particular time is determined by the

supply of the most limited resources

The density of a population is

the number of individuals per unit area

movement of people into cities from rural areas

urbanization

Between 1880 and 1930 human population doubled due to

-a combination of high birth rates and lowered death rates -the Industrial Revolution - improvements in societal infrastructure and services

Why do contagious diseases spread more readily in denser populations?

Because there are more organisms to get that disease, and them being closer together will make them catch the diseases.

What are the advantages of slower population growth?

The habitat can adapt as the population grows.

What are some benefits of Biodiversity?

The habitats are even, and the carnivores make sure there isn't too many herbivores

If a population of rabbits experiences exponential growth, what might happento the population of coyotes in the area? Explain your reasoning.

The population on coyotes will increase due to the fact that coyotes eat rabbits, and more rabbits there are, more food for the coyotes leading them to be in that area more.

A species of plant has exponential growth after it is introduced into an area where it has never been. Which statement best describes exponential growth?

Within a few years the population increases

Competition for food cannot occur

between animals from two different ecosystems

In which of the following types of interactions is neither species harmed?

commensalism
