Multiple Choice

What would happen to heterotrophs if all autotrophs (plants, trees, algae) went extinct?

1

Heterotrophs would eventually die out too

2

Heterotrophs would take over the world

3

Heterotrophs would have to eat each other

4

Heterotrophs would do just fine

3

All organisms need nutrients!

Nutrients and energy are transferred from organism to organism and ultimately returned to the soil, which is used by plants.

Nutrients are cycled in an ecosystem

6

​Biochemical cycles

Definition

  • Recycling of inorganic matter between living organisims and their non-living environment.


  • Cycle that moves and element from one or more environmental reservoirs.

Types of cycles

  • Hydrological (water) cycle

  • Carbon Cycle

  • Nitrogen Cycle

  • Phosphorous Cycle

Poll

Select all of the following terms that looks familiar

Precipitation

Condensation

Evaporation

Transpiration

Groundwater

11

Hydrological Cycle

Hydro(Water) the process by which water is conserved and recycled on Earth's Surface; Driven by The SUN

12

Water's many forms

  • Solid - Ice, Snow, Sleet, Hail

  • Liquid - Oceans, streams, rivers, bays, lakes, groundwater, clouds

  • Gas - Water Vapor

Multiple Choice

What is the Energy Source for the Hydrological (Water) Cycle

1

Sun

2

Rain

3

Wind

4

Oceans

14

Multiple Choice

What is water called in its gas form?

1

Precipitation

2

Ice

3

Water Vapor

4

Air

15

Water in the Atmosphere

  • Precipitation- Condensed water falls back to earth from the atmosphere

  • Sublimation- Snow and Ice going directly to the atmosphere (Solid to gas)

  • Evaporation- Liquid water going into the atmosphere as a gas (largest source of Water Vapor)

  • Condensation- Water Vapor(Gas) converting to liquid water. Forms as clouds

Multiple Choice

What process forms clouds?

1

Condensation

2

Evopotranspiration

3

Sublimation

4

Evaporation

Poll

Which of the following do you think are precipitation?

Sleet

Snow

Hail

Rain

Dew

18

Water Cycle on the surface

  • Ice and Snow- Cap mountains around the planet and the polar regions

  • Runoff- When water is precipitated and move to a place of accumulation (snowmelt or surface)

  • Evapotranspiration (transpiration) Water evaporating directly from a plant rather than water source

  • Freshwater and Oceans - Places where liquid water accumulates

media

19

Water Cycle in the ground

  • Infiltration- the process of water seeping into the ground

  • Groundwater Storage- water stored in the ground (will return to the atmosphere through evaporation)

  • Plant uptake- Water being drawn into plants to be used for photosynthesis

media

20

Multiple Choice

If groundwater reaches earth's surface, how does it reenter the water cycle?

1

by transpiration

2

by evaporation

3

by accumulation

4

it can't
