Let's look at some habitats and identify the niches

for several organisms here in GA

Climate

We organize our lives by knowing the weather and climate of

our local area.

How do scientists measure climate?

Open Ended

Grassland animals adaptations

●
Animals in the grassland

biome have many

adaptations that help them

survive in this unique

environment:

•
Camouflage

•Many grassland animals have
tan or striped fur that helps

them blend in with the
grasses and hide from

predators. They may also use

camouflage to stalk their

prey.

•
Burrowing

•Some animals, like bison,

have front legs and paws that

allow them to burrow into
the ground to hide from

predators and escape the hot

sun.

•
Social behavior

•Grassland animals often live
in social groups to help them
find food, raise young, and

watch for predators.

•
Digestive systems

•Herbivores have evolved

digestive systems that allow

them to survive on

grasses. For example, bison

have broad, flat-topped

teeth.

•
Other adaptations

•
Other adaptations include
hooves for running on plains,
strong claws that can be
withdrawn inside their toes,
eyes on the sides of their
heads, and enzymes for
digesting grasses

Aquatic Biomes

Mr. Allen's Environmental Science
Today-look back if you need to do the SEV 1d and SEV 1e progress learning. You will see a new assignment in progress learning if you need to update it.
Check your Frayer model assignment-hint I know if you opened it up I can give pointers if your working on it in class.

Open Ended

What do you think will happen to the water?

Standard

SEV1. Obtain, evaluate, and
communicate information to

investigate the flow of energy and

cycling of matter within an ecosystem.

e.. Plan and carry out an investigation of how chemical and physical properties impact aquatic biomes in Georgia. (Clarification statement: Consider the diverse aquatic ecosystems across the state such as streams, ponds, coastline, estuaries, and lakes.)

Learning Target

I can identify the chemical properties of water

I can identify freshwater biomes vs marine biomes

I can identify ecosystems lentic vs lotic freshwater systems.
I can identify marine coastal ecosytems coral reefs vs deep ocean

• a. the bond between two hydrogen atoms within a molecule of water

• b. the bond between hydrogen in one water molecule and another hydrogen in a different water molecule

• c. the bond between hydrogen and oxygen within a molecule of water

• d. the bond between hydrogen in one water molecule and oxygen in a different water molecule

Multiple Choice

Which property of water provides the cooling effect of sweating?

• a. cohesiveness

• b. surface tension

• c. high heat of vaporization

• d. adhesiveness

Multiple Choice

Water molecules move farther apart when water freezes, causing it to expand. Which of the following is a consequence of this property?

• Only a limited amount of solute can be dissolved in a sample of water.

• Objects with a higher density than water can be observed floating on water.

• The water in lakes, ponds and puddles freezes from top down.

• Water is considered to be a universal solvent.

Fill in the Blank

Water molecules stick to other water molecules. This property is called __________.

Multiple Choice

Why is water often called a Universal Solvent?

• ice floats on water

• Water is polar and therefore dissolves many other substances

• water exists in three states of matter

• water has adhesive and cohesive properties

Aquatic Biomes

The aquatic biome is the largest of all the biomes, covering about 75 percent of Earth’s surface. This biome is usually divided into two categories: freshwater and marine. Typically, freshwater habitats are less than 1 percent salt. Marine life, however, has to be adapted to living in a habitat with a high concentration of salt. Freshwater habitats include ponds, lakes, rivers, and streams, while marine habitats include the ocean and salty seas.

Multiple Choice

The aquatic biome is the second largest biome in the world.

• TRUE

• FALSE

Multiple Select

Which of the following are considered categories of the aquatic biome? (SELECT 2)

• freshwater

• marine

• mud puddles

Freshwater

Ponds and lakes are both stationary bodies of freshwater, with ponds being smaller than lakes. The types of life present vary within lakes and ponds. In the shallow, sunny waters there is an abundance of life, such as various species of fish. In the deep, dark waters, however, decomposers thrive.

Multiple Choice

Some types of bacteria are decomposers. Where do bacteria tend to live in a pond or lake?

• shallow, sunny waters

• deep, dark waters

• at the bottom of the ocean

Multiple Choice

Ponds and lakes are stationary bodies of water.

• TRUE

• FALSE

Freshwater

Rivers and streams are moving bodies of freshwater. The water in a river or stream is largely made up of runoff from sources such as melting glaciers or rainwater. Rivers and streams usually empty into a lake or the ocean. At the beginning of a fast-moving river or stream, the water is clear and oxygen is abundant. As the water flows, however, it may pick up debris, making the river or stream increasingly cloudy. Oxygen levels may subsequently be affected.  

Multiple Select

Which of the following are true of rivers and streams? SELECT ALL THAT APPLY

• They are moving bodies of water.

• They are largely made up of runoff from glaciers or rainfall.

• They usually empty into a lake or the ocean.

• The water is usually clear where a river or stream begins.

Marine

The ocean is a large body of saltwater that spans most of Earth’s surface. Like ponds and lakes, life in the ocean is adapted to certain regions of the water. For example, the deepest parts of the ocean are too dark to support photosynthesis, but many creatures still manage to survive here. In these regions, the food chain is based on bacteria that perform chemical reactions to obtain energy, also called chemosynthesis. In shallow ocean waters, coral reefs can form. These structures look like shelves of rock, but they are actually made of living animals, called corals, with a calcium carbonate skeleton. Coral reefs are incredibly diverse, hosting over a thousand species of fish. Currently, coral reefs are in danger due to human-caused climate change, which has led to the ocean growing hotter and more acidic.

Multiple Choice

Why do some organisms go through a process called chemosynthesis?

• it's by choice

• chemicals are good for you

• sunlight cannot reach their habitat

Estuaries

Estuaries are regions where freshwater and ocean water mix. Life in estuaries must be adapted to this mixture of saltwater and freshwater. Estuaries are home to many species of fish and shellfish, as well as several species of migratory birds that depend on estuaries for a place to nest and raise their young.    

Multiple Choice

Salinity is _______________.

• the amount of salt present in water

• the name of a science rock band

Multiple Choice

The three main factors that influence life in aquatic biomes are ______________.

• pollution, boats, and volcanoes

• salinity, depth, and speed of water flow

• rising tides, salinity, and temperature

Multiple Choice

Estuaries are bodies of freshwater only.

• TRUE

• FALSE

Estuaries

Estuaries are regions where freshwater and ocean water mix.
