Basic Definitions
Levels of Organization
Energy Relationships
Survival Relationships
Biomes
100
the branch of Biology that studies living things and how they interact with their environment
What is ecology?
100
An individual living thing
What is an organism?
100
grass --> mouse --> hawk
What is a food chain?
100
Identify the three types of survival relationships
What are mutualism, commensalism, and parasitism?
100
an extremely cold, dry biome characterized by grasses, permafrost, and the absence of trees
What is the tundra?
200
sunlight, rain, and soil are examples
What are abiotic factors?
200
lions, hyenas, and zebras all living in the same area
What is a community?
200
Several interacting food chains
What is a food web?
200
an example might be bees and flowers
What is mutualism?
200
the biome boasting the greatest amount of biodiversity on the planet
What is the tropical rain forest?
300
A lion's might include the fact that they are carnivores, consumers, and predators
What is a niche?
300
the human species is an example of one
What is a population?
300
The three major classes of organisms that all ecosystems must have
What are producers, consumers, and decomposers?
300
an example might be the remora and the shark
What is commensalism?
300
your biome, characterized by moderate temperature and broad-leafed trees that grow and lose their leaves each year
What is the temperate (deciduous) forest?
400
sponges, fungi, and bacteria are examples
What are biotic factors?
400
Temperature and precipitation are the single most important factors in determining them
What are biomes?
400
Predict what would happen to the following food chain if a grey wolf were introduced grass --> deer --> black bear
AWV but will include: the wolf is a competitor for the black bear, and will compete for the deer as a prey source. As a result black bear population may decrease, and deer population would almost definitely decrease. As a result grass population would increase...
400
Provide two examples of parasitic relationships.
AWV, but include examples like: dog and tick; human and tapeworm; human and leech; etc. (cases in which one benefits at the expense of the other)
400
The two factors that most impact the formation of a biome, and therefore all plant and animal life within it
What are temperature and precipitation?
500
Provide three examples of heterotrophs.
Answers will vary, but must include examples of consumers.
500
From smallest to largest, identify the 6 levels of ecological organization in their proper order.
What are organism, population, community, ecosystem, biome, and biosphere?
500
Identify the secondary consumer in the following food chain: seeds --> kangaroo rat --> mojave snake --> Chihuahuan raven
What is the mojave snake?
500
Predict how the introduction of spiders which feed on deer ticks might impact the deer population.
AWV, but will be similar to: As spiders are natural predators of the deer tick, they will likely decrease the population of deer ticks, thereby reducing the number of parasitic infections by deer ticks upon deer. Deer populations might increase as a result.
500
Choose one biome and describe: its average temperature, its average precipitation, three examples of plant life, and three examples of animal life.
Answers will vary (AWV). An example might be: Temperate (Deciduous) Forest; moderate temperatures; moderate precipitation; oaks, elms, poplars; bears, squirrels, foxes
