the chemical reaction that breaks down glucose and creates ATP.

C6H12O6 + O2 --> CO2 + H2O + ATP

Who does it? Plants, Animals, Decomposers

Two kinds of cellular respiration: aerobic and anaerobic

# data[].attributes.body
It cannot be created or destroyed, only transformed or transferred.

# data[].attributes.body
Adenonsine triphosphate

ATP is energy that our cells need to do work.

# data[].attributes.body
requires oxygen and takes place in the mitochondria.

creates 36 ATP molecules

Welcome to Crash Course Kids! This bi-weekly show from the producers of Crash Course is all about gradeschool science. We'll look at Earth, Habitats, Space, Chemical Reactions, Engineering, and much much more with host Sabrina Cruz. So, join us every Tuesday and Thursday for new uploads.

does not require oxygen and takes place in the cytoplasm.

creates 2 ATP molecules

Example: fermentation-

Alcoholic fermentation is what happens with the yeast when you make bread.

# data[].attributes.body
a chemical process that uses energy from the sun to create sugar (glucose) and oxygen (O2)

CO2 + H2O + Light --> C6H12O6 + O2

# data[].attributes.body
This is the amount of photosynthesis that is happening.

Productivity increases when water, light, and carbon dioxide are available.

Productivity decreases when there is a lack of water, light, and/or carbon dioxide available.

# data[].attributes.body
The site of photosynthesis in plants.

Chloroplasts are found in the green leaves of plants.

# data[].attributes.body
The pigment in chloroplasts.

It absorbs the light from the sun.

It reflects green and yellow which is why most plants are green.

Homeostasis: Positive and Negative Feedback

# data[].attributes.subject
Homeostasis: Positive and Negative Feedback

# data[].attributes.body
Negative: Up and Down

Example- Temperature regulation

Positive: One direction (only up or only down)

Example- Blood clotting

# data[].attributes.body
Decomposers have the important job of breaking down dead matter in order for the matter to cycle through the ecosystem.

Example: fungi like mushrooms

# data[].attributes.body
The solid Earth: the continental crust and the ocean crust.

Contains NON-LIVING factors: rock, soil

Geo= Earth

Examples: a volcano, a mountain, a hill, underground

# data[].attributes.body
organisms that use energy from the sun to create their own food.

Autotrophs are also known as producers. Think about the produce section of a grocery store, that's where all the vegetables and fruits (plants) are.

Examples: trees, grass, flowers

# data[].attributes.body
organisms that need to consume (eat) other organisms for food (energy)

Examples: humans, dogs, cats, bears, squirrels

# data[].attributes.body
The substances that are created in chemical reactions.

In a chemical equation, they are AFTER the arrow.

In photosynthesis, the products are:

Sugar (Glucose- C6H12O6), Oxygen (O2)

In cellular respiration, the products are:

Carbon dioxide (CO2), Water (H2O), ATP (energy)

# data[].attributes.body
The things that go into a chemical reaction to create new substances.

In chemical equations, they are BEFORE the arrow.

In photosynthesis, the reactants are:

Carbon dioxide (CO2), Water (H2O), Sunlight (energy)

In cellular respiration, the reactants are:

Sugar (Glucose- C6H12O6), Oxygen (O2)

# data[].attributes.body
Contains ALL water on Earth. Only 3% of the water is "fresh" water that we can drink. Most of the freshwater is frozen.

HYDRO= water

Surface water

oceans, lakes, river

Groundwater

Water trapped in the soil

Water in the atmosphere as vapor

Frozen water

ice caps, glaciers

# data[].attributes.body
The life zone; includes all living organisms and all organic matter that has not yet decomposed.

BIO= Life

Animals, plants, bacteria, fungi

# data[].attributes.body
The volcano is part of the geosphere.

When it erupts, it is sending gases out into atmosphere.

# data[].attributes.body
Hurricanes involve the interaction between warm and cold winds.

When these winds meet over water, the atmosphere is interacting with the hydrosphere.

# data[].attributes.body
Respiration and Photosynthesis: in both processes, a gas is produced.

When animals (living) exhale carbon dioxide and when plants (living) release oxygen, they are interacting with the atmosphere.

# data[].attributes.body
A tsunami can occur when an underwater volcano erupts or when there is a shift in the tectonic plates (earthquake).

The underwater volcano and tectonic plates are part of the geosphere. When it creates a tsunami, the geosphere is now interacting with the hydrosphere.

# data[].attributes.body
Percolation occurs when water seeps into the land and filters through the many layers. The water is then stored in the aquifer. The water will also flow out to the nearest water storage like a lake or ocean.

# data[].attributes.body
When water is turned into a water vapor (gas) and enters into the atmosphere, we call that evaporation.

Think of the word "vapor."

# data[].attributes.body
Precipitation includes: rain, sleet, snow

When a solid or liquid form of water falls from the sky.

# data[].attributes.body
When water passes through a plant and leaves the plant as water vapor, this is called Transpiration.

# data[].attributes.body
Respiration

# data[].attributes.body

What Is Eutrophication | Agriculture | Biology | FuseSchool

# data[].attributes.body
More nutrients=more growth of surface plants (algae)

More algae= more death of plants below the surface

Death of plants below the surface= increase of decomposers

More decomposers= more oxygen used up

More decomposers using up more of the oxygen= death of aquatic animals and plants

More death= more decomposers= more oxygen used up= more death= more decomposers= more oxygen used up

THE CYCLE KEEPS ITSELF GOING

Fertilizers from farms can cause eutrophication

# data[].attributes.subject
Fertilizers from farms can cause eutrophication

# data[].attributes.body
Fertilizers contain nitrogen.

When it rains, runoff will take the chemicals from the ground and wash them into our water sources.

# data[].attributes.body
Bacteria are in the roots of the beans. Bacteria is what helps put nitrogen into the soil.

# data[].attributes.body
Corn, Beans (Legumes), Squash

# data[].attributes.body
The three sisters have a mutual symbiotic relationship.

Each helps the other to grow.

Corn- offers structural support for the beans to grow

Beans- take nitrogen from the air and the vines pulls the three sisters together

Squash- leaves keep surrounding soil cool and protection from animals
