Biodiversity loss
10 important questions on Biodiversity loss
From top to bottom, which dimensions can be identified in the ecology sector?
Continental
Biome
Region
Landscape
Ecosystem
Stand or field
Plant
What is the keeling curve?
-Burning of fossil fuels
-Deforestation
-Cement making
Why is the amount of CO2 in the atmosphere, as shown in the keeling curve, dependent on the seasons?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How come human emissions of CO2 are so signifficant when they only make up a few percent of the total CO2 emissions on the earth?
What is the direct influence of increase of CO2 in the atmosphere?
-Enhanced growth due to CO2 fertilisation
-Changes in vegetable structure and patterns because of enhanced water use efficiency of the plants (enabling the plants to deal with draught better).
What is the direct effect of changing climate (due to increase in CO2in atmosphere)?
-Changes in decomposition
-Changes in vegetation patterns
What is the indirect effect of climate change (due to increase of CO2 in atmosphere)?
-Changes in disturbance regimes (eg. more fires in a certain area)
Apart from rising temperatures, what is a mayor effect of climate change that is difficult to deal with.
Why is it that in some figures a reduction in CO2 emission is visible, but the concentration in the atmosphere keeps increasing?
A temperature rise of how much can impact worldwide ecosystems drasticaly?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
