Species Interactions
This term describes a relationship where both species benefit.
What is mutualism?
This biome has permafrost
Tundra
The major reservoir of carbon is this.
What are sedimentary rocks or fossil fuels?
The equation for net primary productivity is this.
What is GPP – R = NPP?
Water vapor forming clouds is this process.
Condensation
If GPP = 4.8 kg C/m²/yr and R = 2.2 kg C/m²/yr, what is NPP?
What is 2.6 kg C/m²/yr?
In this type of competition, members of the same species compete for resources.
What is intraspecific?
Tropical rainforest
In the nitrogen cycle, this process converts N₂ gas into ammonia.
Nitrogen fixation
Only this percent of energy transfers between trophic levels.
What is 10%?
This cycle is powered primarily by the sun.
Hydrologic cycle (water cycle)
The independent variable is the one that is...
changed
This relationship occurs when one organism benefits and the other is unaffected.
What is commensalism
This biome has grasses, a dry season, and supports large grazers.
What is Savanna
The phosphorus cycle is unique because it lacks this component.
What is atmospheric component
The remaining 90% of energy is converted into this form.
What is heat
Humans impact the hydrologic cycle by paving land, which reduces this process.
What is seepage/percolation?
The dependent variable is the one that is...
measured/observed
When one species outcompetes another, what happens to the losing species’ population?
It decreases
As climate warms, temperate forests will shift in this direction.
What is toward higher latitudes (north in the Northern Hemisphere)?
Too much nitrogen or phosphorus in water leads to this process.
What is eutrophication
Which terrestrial biome has the highest NPP?
What is tropical rainforest
The major reservoir for nitrogen is this.
What is the atmosphere?
Why is a control needed in an experiment?
baseline for comparison
Give an example of resource partitioning
Birds using different parts of a tree to avoid direct competition.
These two biomes have the most nutrient-rich soil.
What are temperate grasslands and deciduous forests?
What are the reactants of photosynthesis?
What are CO₂, H₂O, and sunlight?
Calculate: if primary consumers have 4000 kJ, how much energy do tertiary consumers have?
What is 40 kJ?
This human activity adds excess nitrogen to ecosystems.
What is fertilizer use or animal agriculture?
The law of conservation of matter means what for biogeochemical cycles?
Matter is cycled, not created or destroyed.
