Station 1: Species Interactions
Part 1: Responses to Predation
For each of the following statements or pictures determine the correct response from the following list:
Camoflauge
Warning Coloration
Mimicry
Moment of truth Defenses (action by prey)
Deceptive Markings
Alluring Coloration
Picture
Description
1.
This a spider, Synemosyna formica, that looks like
an ant species to avoid predation from birds
mimicry
2.
This lizard’s tail is blue to attract predators to a
non vital body part.
Alluring coloration
3.
The moth has markings that look like eyes.
Deceptive markings
4.
The peacock flounder can change colors to match
its surroundings.
camouflage
5.
Bright orange color tells predators that they are
toxic.
Warning coloration
6.
The beetle releases a strong odor to distract
predators.
Action by Prey
Part 2: Species Relationships
For each of the following statements or pictures determine which type of relationship is occurring:
Mutualism
Predation
Commensalism,
Parasitism
Intraspecific Competition
Interspecific Competition
Competitive Exclusion.
Niche/Resource Partitioning
7.
11.
Remora fish eats left over’s that the
shark catches. commensalism
8.
Parasitism
12.
Male giraffes compete for mates.
Intraspecific competition
9.
10.
Competitive exclusion
13.
Different plant species having different
root depth. Niche/resource
partitioning
Ants hollow out the large thorns of the 14.
Acacia trees for nests and feed on
sweet secretions from leafs. The ants
in return protect the trees from
herbivores that would eat the leaves.
With a movement of the branch, ants
emerge and release a nasty odor and
attack the herbivore. mutualism
predation
Two different species compete for the
same limited resource
Interspecific competition
Station 2: Community Ecology
Part 1: Community Properties
1. Which site has higher species richness? Why?
A. because it has more species
2. Which site has more evenness? Explain why?
B. because the relative abundance of each species is the same.
3. Which site has more biodiversity?
Site B because it has more than one species and it even.
4. What is the trend in species richness as you move closer to the equator?
It increases
5. Name the concept shown in this graph (above).
Species-area-effect
6. Explain this concept.
The larger the island, the more species are found on it.
Part 2: Succession
7. Define Succession.
Sequential growth of an ecosystem.
8. Create a double bubble comparing and contrasting Primary and Seconday succession. Must have
one similarity and two differences.
Part 1: Ecosystem
Station 3: Biomes
1. Describe which parts of Earth are found in each of the following:
a. Geosphere
b. Hydrosphere
c. Atmosphere
d. Biosphere
Part 2: Biomes
1.
Complete the following chart
Biome Name
Temperature
Tundra
Taiga
Temperate
Forest
Tropical
Rainforest
Desert
2.
Using the following graphs: Identify each biome.
A. rainforest B. Tundra C. grassland D. Desert
Precipitation
Soil Description
permafrost
Station 4: Humans and the Environment
Part 1: Environmental Solutions
1. Define the following:
a. Biodiversity Hotspot
b. Ecological (Carbon) Footprint
c. Sustainability
2. What is ecotourism and how does it benefit the environment?
Part 2: Environmental Issues
1. Using the image to the right: Explain how DDT in the water
ends up harming the fish-eating bird. (Must use the terms
bioaccumulation and biomagnification in your explanation).
2. What causes acid precipitation to become acidic?
Burning of fossil fuels creates sulfuric and nitric acid gas
which mixes with the water vapor in the atmosphere
lowering it’s pH.
3. What are the health risks to humans if we destroy the ozone (O3) layer (hint: what does the ozone
layer absorb)? Skin cancer
4. Using the image below:
a. What environmental issue is being demonstrated?
Global warming
b. Explain how green house gases keep the planet warm.
they trap heat from the sun
