What percent of the air is oxygen?
21%
True or false. The plants in a watershed hurt the watershed.
False, they are beneficial.
Why do many states and countries search visitors for fruits and vegetables?
So they don't bring in invasive species of plants or bugs.
Name all the trophic levels, start to finish.
Producers, primary consumers, secondary consumers, tertiary consumers.
How do the blind shrimp and the goby benefit from each other?
The blind shrimp digs and creates a home for the Goby and the Goby watches out and warns the shrimp if there is danger.
What are the 3 of the 4 things that use up oxygen?
1. Ozone formation. 2. Rusting or Oxidizing of metals and minerals. 3. Fire 4. Respiration.
1. Fixation, 2. Uptake, 3. Mineralization, 4. Nitrification, 5. Denitrification
The nutrients that fuel algal blooms typically come from Home Depot and Garden stores. Based on your knowledge of the water cycle, how are the algae acquiring these nutrients?
Rain falls on people's lawns and creates surface runoff drains into a watershed that enters our streams, rivers, lakes, and oceans.
What is a tertiary consumer?
One that eats secondary consumers.
In Module 3, learning about subkingdom protozoa under kindom protista, we saw an example of mutualism with one of the mastigophorites. What was it?
Trychonympha eating cellulose so the termite can eat wood.
What do plants do with the extra food they make.
They store it for later and produce more oxygen than they use.

Give an example of mutualism inside human bodies.

78%
A group of populations living in the same area.
Community
Based on the trophic levels, can the world feed more vegetarians or meat-eaters.
Vegetarians
Is photosynthesis the only way for oxygen to be produced?
No, ozone destruction and water vapor destruction can also produce oxygen.
What is the evaporation from leaves?
Transpiration
How does gaseous nitrogen become liquid nitrogen?
Pressure tanks that look like scuba tanks push the nitrogen molecules together until they are so close they have no choice but to be a liquid.
An Association of living organisms and their physical environment.
