Populations
A group of the same species of individual organisms living in the same area
Population
Biotic and abiotic factors that indicate a stream’s health
Water Quality
Newly exposed or newly formed rock is colonized by living things for the first time.
Primary succession
Water that flows over the land from precipitation or melting of snow or ice.
Runoff
In Jurassic Park, scientists bring back extinct species using DNA. If all dinosaurs came from similar genetic material, would the park have high or low species richness?
What is low species richness?
All the populations of different species of organisms living in the same area and how they interact with each other.
Community
Caused by waste, derived from plants and animals, which can negatively impact aquatic ecosystems by depleting oxygen
Organic pollution
An area previously occupied by living things is disturbed then recolonized following the disturbance. Soil remains after the disturbance.
Secondary succession
Loss of water from the leaf, how plants interact with the water cycle
Transpiration
In Moana, when the heart of Te Fiti is stolen, crops die and fish disappear. What term describes an ecosystem’s ability to bounce back after such a disturbance?
What is resilience?
Largest number of individuals of a population that a environment can support
Carrying Capacity
True or False
If organisms are found in a stream with high sensitivity score to pollution, that indicates that the stream is healthy.
True
True or False: Most bird species are typically considered secondary and tertiary consumers because they rarely obtain their energy directly from plants.
False
Relative abundance of the different species in an area
Species evenness
In Finding Nemo, the fish tank characters all live in a glass box. If they all depend on the same water quality, what factor—biotic or abiotic—is the water?
What is an abiotic factor?
Parasitism and disease are density ___ limiting factors
Density dependent
What is the deepest region of the ocean called?
Hadal zone
What might happen if you remove a primary consumer from the ecosystem?
The number of producers would increase
How many layers of the rainforest are there, and what are they called?
Four: Forest floor, understory, canopy layer, emergent layer
In Avengers: Endgame, after the Blip wipes out half of life, nature seems to recover. If fewer people means less pressure on resources, which ecological factor changed?
What is population size or carrying capacity?
In what month was carrying capacity reached on this graph?
Month 7
Calculate the species richness for the following example: 10 snails, 20 leeches, 50 crayfish, and 20 water striders
Species richness of 4
Fill in the blanks based on the fire and soundscape investigation we completed: If the amount of _______ increases, then the number of ________ recorded in that area will increase.
Fire, bird species
Fill in the blanks based on the transpiration investigation we completed: If the amount of ______ increases, the amount of ________ will significantly increase because the water vapor of the surrounding air is lower than the water potential of the leaves.
Wind, water loss (transpiration)
In Wall-E, Earth becomes uninhabitable due to pollution and trash. What kind of succession would be required for nature to return to this barren landscape?
What is primary succession?
