Get Plants And Snails Answer Key Pdf

Snails generate CO2 that elodea convert into sugar. Elodea produces the O2 and glucose that the snail will consume.

The water remained yellow because, even though it was placed in the light, a snail cannot photosynthesize and produce oxygen, only breathe out carbon dioxide.

1 snail and 2 plants needed to keep a stable environment because it takes the oxygen and releases carbon Dioxide from the 12 hrs in the light.

Plants and animals both release carbon Dioxide at night.

What gas do plants give off in the dark? Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.

Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.

Snails generate CO2 that elodea convert into sugar. Elodea produces the O2 and glucose that the snail will consume.

They are exposed 24 hours of dark and light conditions. When the plant and snail are placed in the dark condition the snail release large amount carbon dioxide.

The water remained yellow because, even though it was placed in the light, a snail cannot photosynthesize and produce oxygen, only breathe out carbon dioxide.

In the Gizmo, students add water plants and aquatic snails to a test tube, then monitor the oxygen and carbon dioxide levels. When only plants are present, the oxygen levels rise and carbon dioxide is depleted. When only snails are present, carbon dioxide levels rise as oxygen is depleted.

1 snail and 2 plants needed to keep a stable environment because it takes the oxygen and releases carbon Dioxide from the 12 hrs in the light.

Snails generate CO2 that elodea convert into sugar. Elodea produces the O2 and glucose that the snail will consume.

What does it tell you when the water is green? There is an equal amount of o2 &CO2.

They are exposed 24 hours of dark and light conditions. When the plant and snail are placed in the dark condition the snail release large amount carbon dioxide.

Plants take in CO2 during photosynthesis and give out oxygen into the atmosphere, while animals take in oxygen and breathe out carbon dioxide during respiration. In this way, plants and animals help each other in the exchange of gases in the atmosphere.
