Week 1: Science-Matter and Energy in Ecosystems

Last updated almost 2 years ago
18 questions
Greetings!

I will grade submissions at least twice per week, so you will know your score in a day or two after you submit. Also, I may add a comment to your answer in Formative. You can also ask me questions through the comment feature in Formative or email me directly at rshaw@fergflor.org.

As lessons are released, they will stay open, so if you miss a week because of a trip, you can catch up. You can also redo any questions or lessons as many times as you wish.

Let's get started!

Sincerely,
Dr. Shaw

In an energy pyramid, approximately 10 percent of the energy available in one trophic level is transferred to the next level. Which statement helps explain why this occurs?

Required
2

Predict the effect is all great white sharks were removed from an ocean ecosystem. (Hint: How would that affect the organisms they eat and the organisms that the sharks prey eat?)

photosynthesis
tiny pores in leaves that absorb carbon dioxide
chlorophyll

Required
1

The main source of energy for plants is water.

Required
2

In the space below, draw and label a diagram of photosynthesis. Be sure to include the terms energy, oxygen, carbon dioxide, water, and glucose.

Required

Read the paragraph below, and then select ALL of the following statements that are correct.
"Most plants grow in soil. They take in sunlight and carbon dioxide through their leaves and nutrients through their roots. Hydroponics is a method of growing plants without soil. Plants are placed in water instead of soil. Even without soil, they still grow."

1

Upload a photo of a plant (inside or outside). Explain where the plant gets water, sunlight, and CO2.
