Week 1: Science-Matter and Energy in Ecosystems

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?

Consumers eat both producers and other consumers.

Organisms use most of the available energy to fuel their own life processes.

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."

Plant roots take in energy from water in the soil.

Plants take in nutrients from the sun through their leaves.

Plant leaves take in carbon dioxide from the water.

Plants take in energy from the sun through their leaves.

Plant roots take in nutrients from water in the soil.

Plants take in nutrients from water even without soil.

Plant leaves take in carbon dioxide from the air.
