How's my Figure?
Figure:
Which organism would have the highest levels of toxin in their body as a result of biomagnification?
What is the Hawk.
Which of the following organisms can feed on more than one trophic level?
a. Decomposers
b. Producers
c. Omnivores
What are:
Decomposers and Omnivores
Which nutrient does not have a global biogeochemical cycle?
What is Phosphorus.
A plant that has root nodules that contain nitrifying bacteria (beans).
What is Legumes.
How does latitude and altitude affect the ecosystems?
Latitude: Colder going up or Warmer going down
Altitude: Warmer going down or Colder going up
Water Cycle:
Label the arrows using these terms:
Condensation, Percolation, Runoff, and Precipitation
Condensation
Precipitation
Runoff
Percolation
How is Carbon stored long term in the Carbon Cycle?
In the Fossil Fuels.
In the Nitrogen Cycle. plants use nitrates and nitrites to form this.
What is nutrients such as amino acids and nucleic acids.
The process by which runoff seeps underground.
What is Percolation.
What are two ways that carbon enters the atmosphere?
Breathing
Cellular Respiration
Burn fossil fuels
Burn wood
*Daily Double*
a. In this figure, which of the following organisms are tertiary consumers?
b. In this figure, which of the following organisms are primary consumers?
a. Fish
b. Copepods
What are three adaptations that plants and animals need to have in order to survive in a desert biome.
1. Water conservation / heat, drink less, cacti store water
2. Big Ears (bunny), store water, urinate less
3. Inside during heat of day, effective H2O loss
Small inputs of this substance can result in algal blooms and dead zones.
What is Phosphorus.
The process by which plants release water into the atmosphere.
What is Transpiration.
What contribution does bacteria make to the nitrogen cycle?
Changes in atmospheric N2 to NH4/NO3
Makes nitrogen usable for plants through Nitrification.Nitrogen Cycle:
Label the cycle with these terms:
Nitrifying Bacteria, Waste, Denitrifying Bacteria, Ammonification
Denitrifying Bacteria
Waste
Nitrifying Bacteria
Ammonification
Describe Nitrogen Fixation.
Bacteria takes nitrogen from the air and converts it to a form usable by plants.
The Hubbard Brook Forest Study demonstrated what?
Deforestation severely alters both the water drainage and nutrient cycling.
Toxins magnify and accumulate as they move up the food chain.
What is Biomagnification.
Name a specific plant that will put nitrogen back into the ecosystem of a farm:
Beans (Legumes)
Clover
Soybeans
Peas
In the Energy Pyramid shown, which level has the smallest number of organisms?
What is the Fox.
Examine the food web shown. What would most likely happen to the organisms in this ecosystem if the algae began to disappear?
The Minnow and bass population would likewise begin to disappear.
Calculate how much energy is available to the tertiary level of a food chain if the primary producers produce 12,345 units of energy. Assume only 10% of energy is transferred from one trophic level to the next.
12,345 -> 1234.5 -> 123.45 -> 12.345 -> 1.2345
Producer Con 1 Con 2 Con 3 Con 4
Top of the food chain who have a disproportional effect when eliminated.
What are Keystone Species
Example: Otter
One of the nutrient cycles moves from an atmospheric gaseous form to a solid through both abiotic and biotic processes, moves through the food web, then is returned to the soil or to the atmosphere. Which cycle fits this description?
What is the Nitrogen Cycle.
