100
what is ecological succession?
a gradual process in which species replace each other over time
100
What is the group of people who lived a nomadic life and hunted giant sloths for food?
Hunter/Gatherers
200
where do consumers get their energy from?
They get their energy from consuming other organisms
200
How is carbon added to the atmosphere?
Carbon is added to the atmosphere through the burning of fossil fuels
200
what are two ways that nitrogen is fixed?
Lightning and nitrogen-fixing bacteria
200
what is the difference between primary and secondary succession?
primary succession occurs where no life existed previously; secondary occurs in an ecosystem where life has previously existed
200
what is the bottom layer of the atmosphere?
troposphere
300
What is the purpose of a food web?
the purpose of a food web is to show you all the various interactions between species in an ecosystem
300
What is the largest carbon reservoir on Earth?
Limestone
300
What does it mean when nitrogen is fixed?
Nitrogen fixation is when the nitrogen is changed into a usable form
300
What is a climax community?
An ecosystem in which ecological succession has basically stopped.
300
what is a biological community?
a group of different populations living in an area
400

deeply buried soil bacteria

freshwater algae

intestinal bacteria


freshwater algae
400
What role do plants play in the carbon cycle?
Plants take carbon out of the atmosphere through the process of photosynthesis
400
Where can phosphorus not be found on planet Earth?
The atmosphere
400
What is the first class of plant to move into a primary successional site?
moss and lichens
400
In what type of environments can you find Archaea?
Extreme environments such as hydrothermal vents and hot springs
500
what is the formula for cellular respiration (write it down)

C6H1206 + 6O2 ---> ATP (energy)

500
What happens to the pH ocean as it absorbs more carbon?
The pH of the ocean decreases and becomes more acidic which is harmful for corals and other wildlife species
500
What happens as excess nitrogen and phosphorus enter an aquatic ecosystem?
A process known as eutrophication occurs in which algae blooms rapidly causing a decrease in oxygen in the ecosystem
500
How could you keep an ecosystem in a certain successional state?
With a regular disturbance such as scheduled fires
