Something Looks Sus'
Directions: Choose one of the problems below to answer:
Part 2
Active Reading
(Explore)
Directions:
Step #1) Actively read the passage making seven annotations as you read in the margins.
Step #2) Remember, annotations include:
a) Word Association Game (example: Cellular Respiration - energy, ATP, mitochondria, oxygen, glucose)
b) Making connections between the text and past lessons, your life, books read, movies, video games etc
c) Rewriting important information in your own words
‼️ Does Not Include Underlining or Highlighting ‼️
Part 3
Because, But and So
(5 min)
Directions:
In three sentences, summarize what happens to the energy in an energy pyramid as it transfers from one trophic level to the next.
1) Sentence one must start with the word BECAUSE
2) Sentence two must start with the word BUT
3) Sentence three must start with the word SO
Model #1:
BECAUSE carbohydrates are our main source of energy, they are an important organic molecule.
BUT carbohydrates are too big to fit into our cells.
SO they must be first be broken into glucose by the digestive system
Model #2:
BECAUSE plants deep in the ocean do not receive sunlight, they can't do photosynthesis.
BUT they are able to make their food using chemosynthesis.
SO they still have stored glucose for cellular respiration.
Part 4
Stop n' Jot
(5 min)
Key Concept #1: The ten percent rule states that each trophic level can only give 10% of its energy to the next level. The other 90% is lost as HEAT & WASTE
Key Concept #2: All energy pyramids start with energy from the Sun which is transferred to the first trophic level of producers. The bottoms of the pyramid always has the most energy. As we go up the pyramid the amount of energy decreases.
Key Concept #3:
Vocab - Trophic Level – Each of the levels in an ecosystem, where organisms share the same function and nutritional relationship within the food chain, food web or energy pyramid.
