imagine you are volunteering in a 1​ st ​ grade classroom. The students recently learned about the water cycle. One student raises her hand and asks, “I heard that elements like carbon can cycle too. How does carbon cycle? Is it like how water cycles?” How would you explain the cycling of carbon to this 1​ st ​ grade class? Keep in mind that the students have likely not taken an advanced science course ​yet​!

Nitrogen ​gas is more abundant in our atmosphere than oxygen! However, nitrogen needs to be converted into different forms to be used by many organisms. Bacteria are highly involved in this! Describe the role of (A) ​bacteria fixing nitrogen as they live symbiotically with some plant species​, (B) ​nitrifying bacteria​, and (C) denitrifying bacteria ​in the nitrogen cycle.

The flow of matter through the carbon and nitrogen cycle can be disrupted! The video clip explained an example in both the carbon and nitrogen cycle. Pick one of these and describe how this disruption could impact cycling.

When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow.

Susan has just moved into a new house. For some reason, she cannot get the grass to grow in her yard. She decides to grow small amounts of grass inside her house as part of an experiment. The first group of grass is exposed to a light intensity of 400. The second group is exposed to a light intensity of 1200.



Using the graph, which of the following should be expected from Susan’s two groups of plants?

Group of answer choices

The plants at a light intensity of 1200 will produce more oxygen than the plants at 400.

The plants at a light intensity of 1200 will perform only stage 1 of photosynthesis.

The plants at a light intensity of 400 will produce more glucose than the plants at 1200.

The plants at a light intensity of 400 will grow more quickly than the plants at 1200.
