My ecological footprint is
Acceptable, I think I live responsably
Too high, I should really make some changes in my life
On earth all life ultimately depends on the energy of the sun
Plants capture the energy of the sun in photosynthesis and use this to produce biomass. The fate of plants is to be eaten (herbivory) or to die and decompose. The flux of energy into...
Herbivory is larger than into decomposition
Decomposition is larger than into herbivory
Two key concepts in ecology are habitat and niche. In a simple way one could say that
A niche is where you live (your address) and your habitat is what you do (your job)
A niche is what you do (your job) and your habitat is where you live (your address)
Nature is in perfect equilibrium. Human disturbance will only upset the balance of nature and in doing so destroy biodiversity
Human brainpower vs natural selection, who wins?
Nature has had 4 billion years to make itself perfect. We humans only appeared recently. It therefore makes sense that photosynthesis captures the energy of the sun more efficiently than solar panels
Evolution is not perfect. And we are clever. Our solar panels are much more efficient than plants in capturing solar energy
Biomes - e.g. tropical rainforest, savnnes, taiga - are biological communities which are adapted to their regeional climate and which extend over large geographic regions. Which of the following factors does NOT contribute to the worldwide distribution of biomes...

I am an ecosystem
If we work in groups of 3 - 4 to prepare the presentation of 2 Ecology papers (one classic and one modern) and if we meet up with the prof to select and discuss these papers one week before we will manage to prepare the presentation for the week thereafter
