Ecosystems
Name 3 Terrestrial and Aquatic Biomes
Terrestrial Biomes: Savanna, Desert, Tropical Rainforest, Subtropical desert, Taiga, Temperate Rainforest
Aquatic Biomes: Oceans, Coral Reefs, Estuaries, Lakes and Ponds, Rivers and Streams, Wetlands, Tundra
Define Biodiversity.
The variety of life, in all it's forms.
The difference of species.
Name all 3 Major Greenhouse Gases.
Carbon Dioxide, Methane, Water Vapor.
Dogs and Ticks are a form of which symbiotic relationship?
Parasitism
A cat and a mouse is this relationship called. (not symbiotic)
Predator-prey
This form of symbiotic relationship benefits both species
Primary: Life colonizes a lifeless area that starts from nothing. (no possiblity of life)
Secondary: The process of ecosystem recovery where a habitat is recolonized following a disturbance that removed vegetation but soil is intact (there is the possiblity of life)
Which Greenhouse Gas does not have a detrimental effect on the atmosphere and why?
Water Vapor since it's short resident time.
According to the 10% rule, if a teritary consumer had 187 kcal, how much did the primary consumer have?
18,700 kcal
If the NPP of a forest is 1012 and the rate of carbon is 945 what is the GPP of the forest?
67
Explain the 10% rule.
10% of the energy gained when eating is given to the predator.
Island 1 has high species evenness
Island 2 has high species richness
Which island's species would be most likely to survive a disruption? Why?
Island 2 due to it's high biodiversity which means that there could be a species that survives it and is capable of repopulating.
Explain Coral Bleaching.
Algae dies or leaves Coral due to it's ecological tolerance which causes the Coral to turn white possibly being fatal.
Diseases are which types of disruptions?
Periodic
Carbon Sinks, Protects soil
Provisioning services
Provides timber, Food and medicine
Cultural services
Tourism
Supporting, Habitat
Name 2 processes of the Nitrogen Cycle and explain them
Nitrogen Fixation: Atmospheric Nitrogen into Ammonia or Ammonium
Nitrification: Ammonia into Nitrites into Nitrates
Assimiliation: Nitrates or Ammonium goes into the soil
Denitrification: Nitrates back into Atmospheric Nitrogen
Ammoniafication: Dead animals/humans producing Nitrogen back into the soil
Explain the theory of Island Biogeography.
Colonization rates against Extinction rates determined by the size and distance an island has (Smaller = higher extinction) (Farther = Lower Immigration/Colonization)
Describe a method of combating anthropogenic activites that affect biodiversity.
Creating protected areas, Promoting sustainable land use practices, restoring lost habitats.
Name one unintended consequence of the Polar Ice Caps melting.
Global sea rise
Costal Flooding
Habitat Loss
Name 3 ways to determine how polluted a body of water is.
If the total GPP of a forest is 118, and the total NPP of the forest is 51. What is the rate of Photosynthesis.
67
Brazil nuts are the largest edible nuts to eat. If this was the only food source for birds on an island, would an island with a high species richness or species evenness is the most likely to go extinct, why?
An Island with a high species evenness would go extinct because the range of beak sizes would have to be big enough to eat the Brazil Nuts.
Explain Eutrophication
the abundance of water by nutrients, primarily phosphorus and nitrogen, leading to excessive algal blooms, severe oxygen depletion (hypoxia), and the creation of aquatic "dead zones", this kills the fish in the water and the algae.
The loss of energy in a trophic pyramid is explained by the laws of...
Name the Nitrogen Cycle in order.
Nitrogen Fixation: Atmospheric Nitrogen into Ammonia or Ammonium
- Nitrification: Ammonia into Nitrites into Nitrates -
Assimiliation: Nitrates or Ammonium goes into the soil
- Ammoniafication: Dead animals/humans producing Nitrogen back into the soil
Denitrification: Nitrate turns into Atmospheric Nitrogen.
