KEYSTONE EXAMS: BIOLOGY ASSESSMENT ANCHORS AND ELIGIBLE CONTENT
ASSESSMENT ANCHORS:
BIO.B.4.2. - Describe the interactions and relationships in an ecosystem.
|
ELIGIBLE CONTENT:
BIO.B.4.2.2 - Describe biotic interactions in an ecosystem (e.g., competition, predation, symbiosis).
BIO.B.4.2.4 - Describe how ecosystems change in response to natural and human disturbances (e.g., climate change, introduction of nonnative species, pollution, fires). |
TO DO:
1. Complete the Biotic Interactions Pre-Test on Google Classroom. 2. Open the Google Doc on Biotic Interactions. You will be completing this as you complete the different tasks. The document can be downloaded below as a Microsoft Word Document. 3. Feel free to watch the video to the right on Predation to refresh on the predator and prey relationships.

5. Using the information below, answer the questions on the google doc labeled "Symbiotic Relationships."
Types of Symbiosis
Mutualism: A type of symbiosis in which both species benefit from the relationship. Example: Bees and flowers are examples of mutualism. As a bee travels to different flowers, it collects nectar, which the bee can use as food. Pollen gets stuck to the bee when it gathers nectar. Pollen gets stuck to the bee, which can fall off when it lands on another flower, pollinating the plant. The bee gets food while the flower gets to reproduction. Parasitism: A type of symbiosis in which one species benefits and the other is harmed. The parasitic species lives in or on the host species. Example: Myrmeconema neotropicum is a unique nematode species that uses parasitism to reproduce. When it is eaten by the South American ant, it causes the ant's gaster to swell and turn a bright red. Birds mistake the ant for a red berry and eat the ant. The bird, when it defecates, will now spread the eggs of the nematode where other ants will ingest them, starting the cycle over again. The nematode gets to reproduce at the expense of the ant. Commensalism: A type of symbiosis in which one species benefits and the other is unaffected. Example: Both whales and barnacles eat plankton, which are microscopic organisms in the ocean. Barnacles are unable to move on their own but can attach themselves to whales. As the whale swims through clouds of plankton, the barnacles are able to feed on plankton missed by the whale. The whales are not harmed by the barnacles while the barnacles are able to get food. This is an example of commensalism. |
