lu5 & lu6 gamification Flashcards
What is the right definition of ecological succession?
The gradual process by which ecosystems change and develop over time.
Which Scenario describes the secondary sucession?
a. abandoned agriculture field
b. glacial retreat
c. sand dune formation
d. volcanic island formation
Lichen is the first organism that inhibit an area after the disturbance.
True
Which one is climax vegetation?
rainforests
Phytoplankton→rooted aquatic plants→free floating stage→reed swamp stage→woodland stage→sedge meadow stage→climax forest
false
P/RAQ/FF/RS/SM/W/CF
Phytoplankton→rooted aquatic plants→free floating stage→reed swamp stage→sedge meadow stage→woodland stage→climax forest
The forest adapts to the enviromental conditions → one of the characteristics of the most climax community. T/F?
true
Which human activities disturb phosphorus cycle?
?
Buffer zones in and around protected areas are a way to mitigate climate change. T/F?
True
Air Quality Index can predict the density of air particles. T/F?
false
The Air Quality Index (AQI) is a numerical scale used to communicate how polluted the air currently is or how polluted it is forecasted to become. It is calculated based on concentrations of various air pollutants, such as particulate matter (PM10 and PM2.5), ground-level ozone, sulfur dioxide, carbon monoxide, and nitrogen dioxide.
The sea level has been increasing since the 20th Century. Is this the effect of climate change? T/F?
true
An increment of oxygen will happen if excess consumers are relative to producers in a pond. T/F?
false
f there is an excess of consumers relative to producers in a pond, it is more likely to lead to a reduction in oxygen rather than an increment. This is because consumers, through respiration, use up oxygen, and if the rate of oxygen consumption exceeds the rate of oxygen production (from photosynthesis), it can result in lower oxygen levels in the water.
After a forest commnity is razed by fire, lichens will grow first and next be replaced by other species. T/F?
true
