Which is one negative effect of fires?

Is when small pieces of rock are carried away by water and sometimes by wind.

It occurs when it does not rain for a long time. It forces people and animals to look for new places to live.

Plants change the environment by __________________

Is a large amount of water that covers normally dry land:

It causes rivers to rise higher and higher:

They caus flame, heat, smoke, and ash, as a result they can change ecosystems:

Where there is not enough rain, _____________ can hurt crops.

A change in the environment can cause an animal to lose its ________________

Shorelines and beaches are worn away by: _________

plants and animals are made sick by: ______

An ______ includes all living and nonliving things together in an area.

What is weathering?

What is sediment?

In the pictures below, choose each picture that shows different types of physical weathering.

In the pictures below, choose a picture that shows physical weathering of rock that has abrasion caused by wind.

In the pictures below, choose a picture that shows chemical weathering of rock.

Which picture shows an animal causing physical weathering?

What are the two types of weathering?

The geological process when rocks or sediments move or are transported from one place to another is:

This plant's roots have grown into gaps in the rock - forcing the rock to break apart. What type of weathering has occurred?

What is deposition?

What geologic process happens when a delta forms as a river is emptied into the ocean?

When temperatures repeatedly go from hot to cold this can cause what type of geological process?

The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation

The change of a substance from a liquid to a gas

Evaporation of water from the leaves of a plant

The change of state from a gas to a liquid

Any form of water that falls from clouds and reaches Earth's surface.

water that flows over the ground surface rather than soaking into the ground

water that fills the cracks and spaces in underground soil and rock layers

A body of rock or sediment that stores groundwater and allows the flow of groundwater.

An ecosystem where all water runoff drains into a single body of water

the level below which the ground is saturated with water.

Which situation best describes the act of maintaining homeostasis?

Identify the stimulus....."Birds flock to shelter when it starts to hail outside

Identify the stimulus..."A loud noise causes you to cover your ears"

Identify the stimulus..."A person shivers because it is cold outside"

Identify the response..."A squirrel scratches at a flea bite"

Identify the response..."An organism is hungry so it eats some food"

Identify the stimulus..."Roots growing down towards gravity"

Identify the response..."A plant's stem fighting against the force of gravity by growing upwards"

Is the stimulus external or internal....A loud noise?

Is the stimulus internal or external? Feeling hungry

Identify the tropism in the picture.

Sunflowers turning towards the sun.

Venus Flytrap flower reacts to a bug.

A plant growing in response to a greenhouse light.

What is the stimulus in this example?

A tropism is...

A change in an organism’s external environment that causes a response from the organism.

A change in an organism’s internal environment that causes a response from the organism.

An organism’s ability to maintain steady internal conditions when outside conditions change, also called maintaining balance.

In plant cells, the force, exerted by the flow of water, within the cell that pushes the plasma membrane against the cell wall. This force gives plants structure and helps them stand up and not wilt.

What plant cell process is being shown in this video after the water is added to the soil?

The plant organelle that uses light energy to make food from water and carbon dioxide in a process known as photosynthesis.

All energy in an ecosystem comes from the sun. This energy is passed through the ecosystem as organisms eat other organsims.

Animal that gets its energy and nutrition from eating plants.

Animal that gets its energy and nutrition from eating meat.

Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.

Organisms that get their energy and nutrition from other organisms (consumers).

Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.

The level in an Ecological pyramid that includes all the organisms that share the same place in a food chain.

Autotrophs--The bottom trophic level where all organisms produce their own food, usually by photosynthesis.

Herbivores--The second trophic level where herbivores eat the primary producers.

The third trophic level where the animals eat herbivores.

The fourth trophic level where animals eat secondary consumers or below.

Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.

Complex trophic relationships in an ecological pyramid.

Parts of an ecosystem that are living or deal with the living. Examples include producers, consumers, decomposers, predation, disease, competition, parasitism, and symbiosis.

Parts of an ecosystem that are not living. Examples: water, soil, sunlight, temperature, altitude.
