AquiferWater-bearing
rock readily transmits water to wells and springs
Precipitation eventually adds water into the porous rock of the aquifer.

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”
![Page 22: Understanding Water and its Role in our Lives and our Environment Water Conservation and Protection in the Barnegat Bay Watershed © Amanda Traina and Louise](https://reader035.vdocument.in/reader035/viewer/2022062301/56649ccc5503460f9499538e/html5/thumbnails/22.jpg)
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
![Page 23: Understanding Water and its Role in our Lives and our Environment Water Conservation and Protection in the Barnegat Bay Watershed © Amanda Traina and Louise](https://reader035.vdocument.in/reader035/viewer/2022062301/56649ccc5503460f9499538e/html5/thumbnails/23.jpg)
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.
![Page 24: Understanding Water and its Role in our Lives and our Environment Water Conservation and Protection in the Barnegat Bay Watershed © Amanda Traina and Louise](https://reader035.vdocument.in/reader035/viewer/2022062301/56649ccc5503460f9499538e/html5/thumbnails/24.jpg)
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

Human Impact on Barnegat Bay Estuary
![Page 37: Understanding Water and its Role in our Lives and our Environment Water Conservation and Protection in the Barnegat Bay Watershed © Amanda Traina and Louise](https://reader035.vdocument.in/reader035/viewer/2022062301/56649ccc5503460f9499538e/html5/thumbnails/37.jpg)
Why Care?Water supply for seaside towns such as
Seaside Heights and Point Pleasant Beach affected
Well for water supply in a coastal town
![Page 38: Understanding Water and its Role in our Lives and our Environment Water Conservation and Protection in the Barnegat Bay Watershed © Amanda Traina and Louise](https://reader035.vdocument.in/reader035/viewer/2022062301/56649ccc5503460f9499538e/html5/thumbnails/38.jpg)
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
