Environmental Science Final Review Pt. 1

Globally, the leading cause of biodiversity loss is

• pollution.

• invasive species.

• poaching and overharvesting.

• habitat change and loss.

What forbids the U.S. government and its citizens from harming endangered or threatened species and their habitats?

• the Environmental Protection Agency

• Species Survival Plan

• the Endangered Species Act

• the Convention on International Trade in Endangered Species

A fish species is introduced to a park pond. Which statement best describes the population growth of these fish shown in the graph?

• The population stopped growing because the fish stopped reproducing.

• The population stopped growing because this species of fish lives less than one year.

• The population grew until disease caused the population to level off.

• The population grew until it reached the pond's carrying capacity.

In many parts of the U.S., native plants that once grew on the forest floor have been replaced by garlic mustard, an invasive species. This situation is an example of

• parasitism between species

• primary succession between species

• predation between species

• competition between species

Which biome has the highest net primary production?

• Desert

• Rainforest

• Grassland

• Boreal Forest

An invasive species can pose a huge threat to an ecosystem or region because

• they are protected and not poached.

• the local organisms do not have a way to protect themselves from these new organisms.

• people have no means of eliminating the invasive species.

• invasive species breed and reproduce more quickly than other organisms.

Approximately how much energy is transferred from one trophic level to the next in an ecological pyramid?

• 10%

• 20%

• 50%

• 90%

Which of the following organisms is a decomposer?

• a plant

• a tiger

• a mushroom

• a deer

What impact does increased education of women have on fertility rates?

• Tend to marry later, and have fewer, healthier children.

• Increased education leads to more wealth and increase in children.

• Educated women tend to not family plan.

• There is no correlation between education and fertility rates.

High birth rates and fertility rates in developing countries such as India have been connected to

• Culture and female social status

• Education and employment of males

• Females over their reproductive age
