Ground Water

Precipitation

Condensation

Infiltration

Run-off

Evaporation

Ground Water enters ocean

Fresh Water Storage

Run-off

Groundwater

AquiferWater-bearing

rock readily transmits water to wells and springs

Precipitation eventually adds water into the porous rock of the aquifer.

Focus on the Barnegat Bay

Water in your Home Ecosystem

Barnegat Bay Watershed

Lands vary from coastal dune, marshes, interior pine barrens

Covers 660 square miles of water, pinelands, towns, and open space!

Salinity levels along an estuary

Ocean RiverFresh water flow

More than 180 species of algae (mostly tiny phytoplankton) reported from Barnegat Bay

Home to more than 100 species of fish

Many species of crab, shrimp, snail, clam etc. live under its waters

Thousands of waterbirds nest on its beaches and fish in its waters

Organisms of the Barnegat Bay Estuary

What is a food chain?A food chain is “a sequence of organisms,

each of which uses the next, lower member of the sequence as a food source1”

What is a producer?An organism that creates it’s own food,

usually through photosynthesis

What can you think of that might be the most common source of energy for all producers?

The SUN

Important facts about food chainsIn a food chain, each organism

obtains energy from the one at the level below.

Plants are called producers because they create their own food through photosynthesis

Animals are consumers because they cannot create their own food, they must eat (consume) plants or other animals to get the energy they need.

Primary ProducersPrimary producers are

“organisms capable of producing their own food”

We can also say that they are photosynthetic, use light energy.

Examples of primary producers include algae, phytoplankton, and large plants.

Primary producers are eaten by primary consumers (herbivores)

Four types of consumerHerbivores: animals that eat only plants

Carnivores: animals that eat only other animals

Omnivores: animals that eat animals and plants

Detritivores: Animals that eat dead materials and organic wastes (aka decomposers)

Other Ways to Classify Consumers1. Primary Consumers:

Herbivores

2. Secondary Consumers: Carnivores that eat herbivores

3. Tertiary Consumers: Carnivores that eat other carnivores

Secondary ConsumersBlue Crab (eats worms, snails, etc.)

Tertiary ConsumersEat other animals in marsh including voles,

fish, and other types of birds

Osprey Sandpiper

OmnivoreMallard ducks eats invertebrates, fish,

amphibians, plants

DetritivoreWorms are common detritivores in many

ecosystems including Barnegat Bay

What is a food web?A food web is “an interlocking pattern of food chains”

Barnegat Bay Estuary

Human Impact on Barnegat Bay Estuary

Why Care?Water supply for seaside towns such as

Seaside Heights and Point Pleasant Beach affected

Well for water supply in a coastal town

Why Care?Too much salt water intrusion into estuary

(resulting from low river flow) can make certain animals in estuary die, along with grasses they eat.

About 85% of the fish and shellfish sold in world spend all or part of lives in estuaries
