100

This sampling tool is usually a square frame placed on the ground to count plants.

Quadrats

100

Living factors in an ecosystem, such as plants and animals, are called these.

Biotic Factors

100

This Earth sphere includes all living things.

Biosphere

100

This process changes liquid water into water vapour.

Evaporation

100

This gas makes up most of Earth’s atmosphere.

Nitrogen

200

This is a tape measure laid in a straight line across a habitat

Transect

200

Temperature, light, and water are examples of these factors.

Abiotic Factors

200

The atmosphere is the Earth’s layer of these.

Gases (or Air)

200

Water vapour cooling and forming clouds is called this.

Condensation
200

The hottest planet in our solar system is this one.

Venus

300

Quadrats are most suitable for studying organisms that do not move much.

Plants (sessile organisms)

300

This biotic factor describes organisms competing for the same resources.

Competition

300

Rocks, soil, and landforms are part of this sphere.

Geosphere/Lithosphere

300

Rain, snow, and hail all fall to Earth in this process.

Precipitation

300

This organ pumps blood around the human body.

Heart

400

Using more quadrats in different locations makes results more reliable because it reduces this.

Bias or Random Error

400

A drought mainly changes this type of factor in an ecosystem.

Abiotic Factors

400

Oceans, rivers, ice, and groundwater are all part of this sphere.

Hydrosphere

400

This process occurs when water soaks into the ground.

Inflitration

400

The process plants use to make their own food using sunlight is called this.

Photosynthesis
