Please help me answer these questions. These questions had to be answered after watching the movie ‘An Inconvenient Truth’. I have done a lot of research but I could not find the answers to these questions. Please do try to answer all the questions (even if you’re not sure) but if even if you can answer a few, it would be greatly appreciated.
1. Who was the first person to propose measuring CO2 levels in the atmosphere?
2. Why do CO2 levels in the atmosphere have such drastic fluctuations within a year?
3. What trends can be seen in CO2 levels from 1958 – 2005?
4. How are scientist able to determine temperature and CO2 levels from specific years so long ago?
5. How recently did the 10 hottest years ever recorded occur?
6. Why did Katrina change from a category 1 hurricane before reaching New Orleans?
7. The ocean currents are interconnected via a conveyor type system. What would happen to this system if Greenland had to melt and why?
8.Describe 3 ecological niches that are affected by global warming?
Thank you so much 🙂

A) Taxonomy is the branch of biology concerned with naming and classifying the diverse forms
of life.
B) The ecological species concept identifies species in terms of their ecological niches.
C) The phylogenetic species concept defines a species as a set or organisms with a unique
genetic history.
D) The morphological species concept relies upon identifying genotypic diversity and
comparing the nucleotides of genes.
E) The biological species concept is useless for organisms that are completely asexual in their
reproduction

For a project, I need to know the ecological niches of these 4 organisms, but I don’t understand what an ecological niche is. Can someone please explain to me the types of niches? Please don’t tell me that it’s a project and to do it on my own, because I have been searching for a really long time now, and can’t seem to find it in my notes or the internet.

Behaviorally how are we and them different toward our ecological niches?

a) Taxonomy is the branch of biology concerned with naming and classifying the diverse forms of life.
b) The ecological species concept identifies species in terms of their ecological niches.
