What produces Earth's magnetic field?

the movement of Earth's tectonic plates

the pressure of Earth's crust upon Earth's mantle

the rotation of Earth's core

the bombardment of Earth's atmosphere by solar particles

1

In which layer of the geosphere does the asthenosphere lie?

core

mantle

oceanic crust

continental crust

When communities form in previous uninhabited areas, this is called .

If the primary consumers in a food chain become extinct, what will most likely happen?

The secondary consumers will also die out.

the secondary consumers will start eating decomposers.

The producer population will die out.

The secondary consumers will become tertiary consumers.

A certain ant species benefits from the food and shelter provided by the acacia tree. If the two species are in a mutualistic relationship, what happens to the tree in return?

The tree dies as a result of the ants' feeding behavior.

The ants attract other plants that compete for the tree's nutrients.

The tree get protection from the ands' defenses.

The tree does not suffer any consequences nor gains any benefits.

1

Which of the following best describes all pioneer species?

species that compete with other organisms

species at the top of the food chain

species that colonize new surfaces

species that cooperate with other organisms

1

Which statement best explains why producers are located at the bottom of the energy pyramid?

They are the source of energy for every other living thing.

There are more producers than any other organism

They require more energy than other organisms.

They are the least important members of the food chain.

1

How do parasitism and predation differ?

In predation, both organisms benefit, while in parasitism, both organisms are harmed.

The goal of predation is to kill the prey, while a parasite does not benefit from killing its host.

Parasitism occurs between microscopic organisms, while predation occurs between larger animals.

Parasitism occurs between a plant and an animal, while predation occurs between two animals.

The number of individuals of the same species in an area is the . The number of individuals living in a specific unit area or volume is the . The manner in which individuals are spread thorughout a given area is the given .

Mmuae Afoforo a Wobɛpaw:

population demographics

population distribution

population density

population size

1

Density-independent factors are often

increase rapidly

decrease rapidly

stabilize

none of these; carrying capacity does not affect population size

1

As a population nears carrying capacity, the growth rate will stabilize. This is a demonstration of

linear population growth

negative population growth

exponential population growth

logistical population growth

1

A population with high infant mortality typically has which type of survivorship curve?

I

II

III

IV

2

Select all of the abiotic factors affecting the aquatic biome.

1

An organism has a respiratory system that can get oxygen from water, one fin on either side of their body, and the ability to expel excess salt. Select the statement below that correctly describes the organism.

The organism is adapted to breathing air because its respiratory system uses oxygen.

The organism is adapted to a freshwater biome because it has fins.

The organism is adapted to a marine biome because it has fins.

The organism is adapted to a marine biome because it can process salt in the water.

1

The taiga biome is most characterized by its

permafrost

high temperatures

grass meadows

coniferous forests

1

What are the most important climate factors that define a biome?

temperature and soil

temperature and precipitation

precipitation and soil

soil and longitude

1

Which of the following is a difference between tropical and temperate rain forests?

Only tropical rain forests contain a great diversity of life forms.

Tropical rain forests are only found at the equator. Temperate rain forests are found in coastal areas around the world.

Tropical rain forests receive hundreds of centimeters of rain. Temperate rain forests receive less than 100 centimeters.

Tropical rain forests are home to a diversity of mammals, while tropical rain forests only have birds, reptiles, and amphibians.

cold and dark.

well illuminated.

rich in coral and other benthic species.

void of life.
