Exploring interactions between organisms in pandora A holistic approach to relationships in ecosystems

Ecology is the Science of relationships. It focuses on the interactions between organisms and their environment.

Activity 1 - abiotic & biotic factors

The environment is made up of two factors:

  1. Biotic factors: All living organisms. This includes plant cells, animal cells and unicellular organisms.
  2. Abiotic factors: All non-living parts of the environment. This includes temperature, soil, rocks, water, and air.

Making Observations: Have a look at the video clip below and make sure to identify a minimum of 5 abiotic and 5 biotic things seen.

Activity 2 - trophic levels and their interactions

Look at the following website and fill in the table below

Watch the video clip again this time take a screenshot of:

  • 1 x Producer
  • 1 x Herbivore Consumer
  • 1 x Omnivore Consumer
  • 1 x Carnivore Consumer

For each screenshot make sure to justify why you have classified it as a producer, herbivore, omnivore or carnivore

Activity 3 - [PBL]

You will be required to design a planet that does not exist and develop a 2-3 minute digital presentation. That explains:

• Name of planet

• Where planet is found

• A satellite image of planet

• A cross section of planet

• Biospheres and different ecosystems

• A list of abiotic and biotic factors

• One functional food chain and images to illustrate

Part 1: Preliminary Research

Part 2: Describe your ecosystem

  • What are the abiotic conditions (e.g., temperature, seasons, climate, pH, humidity, soil, terrain)?
  • What are the biotic factors (e.g., the producers; decomposers; primary, secondary, and tertiary consumers)?
  • Sketch a food chain found in your ecosystem.
  • Make a folder with images you could use for animal creation as inspiration. You will need these if you use photoshop
Photoshop workshops below on:

Part 3 - Presentation

You may choose to present using:

  1. Adobe voice
  2. Comic strip maker
  3. Trailer video on Imovie

If you would like to use a different method of presentation consult with your teacher for approval.

Activity 4 - symbiotic interactions

Visible Thinking

SEE: Look at the images above and write down 6 things you notice.

THINK: What interactions can you notice? Are they positive, negative or do you believe they have no effect on the organisms interacting?

WONDER: Let your mind wonder and think about things that might not make sense to you. Come up with 5 questions you could investigate with regards to the images above.

Have a look at the web resource below and answer the following questions
  1. Identify the differences between mutualism, comensalism and parasitism.

2. Classify mutualism, commensalism and parasitism as either a beneficial or detrimental interaction.

3. How are symbiotic relationship and trophic levels interrelated.

Activity 5 - CONCEPT CHECKPOINT

If you were to write a headline for this topic or issue right now that captured the most important aspect that should be remembered, what would that headline be?
