100

This term describes living components of an ecosystem, such as plants and animals.

Biotic

100

This type of growth happens when resources are unlimited and population size increases rapidly.

Exponential Growth

100

This is the lowest layer of the atmosphere where weather occurs.

Troposphere

100

This biome is characterized by very low rainfall and extreme temperatures.

Desert

100

This Earth system includes all of Earth’s water.

Hydrosphere

200

Nonliving parts of an ecosystem like water, temperature, and sunlight are called this.

Abiotic

200

This type of population growth slows as it approaches carrying capacity.

Logistic Growth

200

This layer contains the ozone layer.

Stratosphere

200

This biome has warm temperatures, heavy rainfall, and high biodiversity.

Rainforest

200

Rain carrying soil into rivers shows an interaction between the geosphere and this system.

Hydrosphere

300

This term refers to the variety of life in an ecosystem.

Biodiversity 

300

This type of succession occurs after a disturbance where soil is already present.

Secondary Succession

300

This layer is the coldest layer of the atmosphere.

Mesosphere

300

This biome is cold, treeless, and has permanently frozen soil called permafrost.

Tundra

300

This gas needs to be converted by bacteria in the soil before it can be used by our bodies.

Nitrogen

400

This describes the role or job a species has in its ecosystem.

Niche

400

This type of succession begins in an area where no soil exists, such as bare rock.

Primary Succession

400

This is the most plentiful gas in the earth's air.

Nitrogen

400

This biome is dominated by grasses and supports large grazing animals.

Grasslands

400

This layer of the atmosphere protects life by absorbing harmful ultraviolet radiation.

Ozone Layer

500

This is the maximum number of individuals an ecosystem can support over time.

Carrying Capacity

500

If a population grows beyond carrying capacity, these outcomes may occur.

Resource depletion, increased competition, disease, or population decline

500

This effect causes winds and storms like hurricanes to curve due to Earth’s rotation.

The Coriolis Effect

500

Which biome would a desert most likely change to if long-term rainfall increased significantly?

Grassland

500

If the ozone layer disappeared, this would likely happen to ecosystems.

Increased UV radiation causing harm to plants, animals, and food chains.
