How long ago did the common ancestor of all the organisms on this phylogenetic tree exist?
Answer must be in between 27mya and 29mya.
200
What is the first species to colonize a newly formed island called?
Pioneer species
200
The result of excess fertilizer in nearby bodies of water.
Eutrophication
300
I have a cell wall made of chitin and feed off dead or decaying organisms.
Fungi
300
Based on this cladogram, which two species have the most DNA similarity?
Pygmy chimps and humans
300
What is the difference between primary and secondary succession?
Primary has no soil and takes longer to recover. Secondary starts with soil and takes less time to recover.

How does excess carbon dioxide in the oceans affect marine life?
Causes ocean acidification. It can lead to coral bleaching and the dissolving of shells. Affects organisms ability to maintain homeostasis.
400
Which organisms are considered eukaryotes?
Organism 1 and organism 4.

Option 1 - The Raccoon and the Red Panda
Option 2 - The Giant Panda and the Spectacled Bear
Option 2 - The Giant Panda and the Spectacled Bear
Explanation - their most recent common ancestor was around ~17mya. The most recent common ancestor of the Raccoon and the Red Panda was around ~23mya.

How do pioneer species like lichen and moss alter their environment?
Help with the formation of soil through decomposition and erosion.

How does deforestation affect atmospheric carbon dioxide levels?
Increase in atmospheric carbon dioxide.

Why are viruses not considered living things?
They do not contain all seven characteristics of life.
They cannot reproduce without a host.

Two correct answers:
500
Wildfires lead to secondary succession. How do wildfires promote growth in communities?
Ash from the fire returns nutrients to the soil.
500
How does excess nitrogen and phosphorus lead to anoxic (oxygen-depleted) zones in the water?
The decomposition of harmful algal blooms reduces the amount of available dissolved oxygen.
