Welcome in our underwater base!
In this class activity we are going to visit the same location in the ocean at two different moments in time. In each moment we will look at the ecosystem and organisms.
Ocean Ecosystem Part 1 and Part 2
Instruction & demonstration
English
Target Age: 9-15
Target Subject/Field: Science, Ecology, Biology
Essential Idea: Systems need to be in balance in order to function effectively.
This ocean habitat is rich with producers, consumers and decomposers. See if you can find most of them.

Goal of the Learning Application:
Students need to be able to observe and monitor changes in ecosystems, and assess the impacts of our actions.
Key Concepts & Vocabulary:
- Change
- Food web
- Food chain
- Habitat
- Balance
- interdependence

Pre-Application Guidelines & Questions (10 mins)
Have students watch this video clip on youtube, https://www.youtube.com/watch?v=FFloV2J-eKI. Ask them to answer these questions:
1) Give an example of each of the following: producer, primary consumer, secondary consumer, and decomposer.
Answers may vary. Producers: plants, algae. Primary consumers: deer, cows, snails. Secondary consumers: seal, sharks, coyote, eagle. Decomposers: Mushrooms, bacteria, earthworms.
2) What is the difference between food webs and food chains?
A food web illustrates the feeding relationships among species within a larger community or habitat, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
A Food chain represents a single feeding relationship and is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. They usually start with a producer
3) Draw a food chain for a prairie ecosystem.
4) Draw a food web for a prairie ecosystem.

Learning goals
Possible Learning Objectives:
- classify organisms according to their role in a food chain: producers, herbivores, carnivores, decomposers
- interpreting food webs, and food chains and predicting the effects of changes to any part of a web
- investigate a habitat, and describe and interpret distribution patterns of living things found in those habitats
- investigate and interpret evidence of interaction and change in order to understand interdependence among all of the organisms inside an ecosystem.
