Food Web Project and Helping Video Links

Watch this video on food webs and how biotic and abiotic factors in an ecosystem are connected.



Amoeba Sisters Video on Food Webs and Energy Pyramids


Food Web Project


Directions:
Create a food web for an ecosystem that is within the State of Maine. For example a forest, field, stream, backyard, saltmarsh, or beach. You are encouraged to choose an ecosystem that you are familiar with. You should organize your food web so that relationships between organisms are demonstrated (like we did in class).

A good way to start:
Brainstorm organisms within an ecosystem (you should have 15-20)
Place the organisms into groups: producer, consumer, decomposer (click to find more).

Vocabulary to keep in mind:
organism
ecosystem
decomposer (click here to learn more)
food web
producer
consumer
trophic level

Checklist of Required Items
Your food web should:

  • have 15 - 20 organisms represented in the food web.
  • identify the name of each organism (this should be specific, do not just list fish or tree).
  • include arrows to indicate the flow of energy (going in the direction that the energy travels)
  • have at least 2 of every trophic level represented (decomposer, producer, consumer).
  • show many organisms interacting.
  • contain a sketch for each organism (computer printed images are OK if you do not like to draw).
  • use a ruler to draw straight lines.
  • contain color.
  • contain a title (example - A Tidal Pool Food Web).
  • contain your name and group.

Trophic Cascades and the Wolves of Yellowstone

Introduction to Ecosystems
NGSS Standards:
MS-LS2.A.2 ( Middle School Life Sciences ): Growth of organisms and population increases are limited by access to resources.
MS-LS2.A.3 ( Middle School Life Sciences ): In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction.
MS-LS2.B.1 ( Middle School Life Sciences ): Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. 
MS-LS2.C.1 ( Middle School Life Sciences ): Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.

Ideas to consider:
1. What is a biotic factor vs an abiotic factor?
2. What is a trophic cascade?
3. How does one organism impact another?

UVA and UVB Rays and Sun Screen

Essential Questions:
What are UV Rays?
How do UV Rays effect your body?
Click on the above link and make a copy  

UVA rays cause skin aging and wrinkling and contribute to skin cancer, such as melanoma. Because UVA rays pass effortlessly through the ozone layer (the protective layer of atmosphere, or shield, surrounding the earth), they make up the majority of our sun exposure. Beware of tanning beds because they use UVA rays as well as UVB rays. 

UVB rays are also dangerous, causing sunburns, cataracts (clouding of the eye lens), and effects on the immune system. They also contribute to skin cancer. Melanoma, the most dangerous form of skin cancer, is thought to be associated with severe UVB sunburns that occur before the age of 20.
