1.What is primary productivity? What do we measure it in? (units)
it's the amount of livable mass is being laid down by producers , It's measured in
grams of carbon per meter square per year
2: What are producers? Who are the main producers in the ocean? How is this measured in
an aquatic environment?
Producers are organisms that can make their own food. main producers in an aquatic environment are algae
3: What is a trophic level? List and define the trophic levels. (Give examples) In which direction does the arrow go in a food web? Explain.
trophic levels are the levels of energy from one organism to other
Producers are organisms that make their own food,
consumers are organisms that can't make their own food,
The second level consumers eat primary consumers.
Third level consumers eat the second level consumers.
The arrow goes up, because it goes up the more energy transferred is to decrease.
4: What is a food web? How is it different than food chains?
food chain is the amount of transferred energy from one organism to other one while food web is a more complicated flow of energy
5: Explain the limiting factors for growth in ecosystems. Explain logistic growth.
Amount of number of a specific creature.
Logistic growth is when growth will eventually reach a
limit.
6: What is the carrying capacity (K) of an
ecosystem?
Maximum level an ecosystem can support.
7: What factors affect the carrying capacity of a population? Explain how wolves and elk populations are linked and how they will reach equilibrium.
Not enough resources for everyone and too much pollution making the world worse.
Elk is the prey of wolves so the increasing of wolves means the decreasing of elks and if wolves decrease the other way around so they should stay equal to maintain equilibrium.
8: Summarize the story of the White bark Pine and how humans can impact an entire ecosystem by choices we make (directly or indirectly).
White bark Pine is a place where there are lots of pine nuts and squirrels. climate change caused by humans and our activities are affecting Yellowstone park. The warming temperature of White bark Pine, animals cannot adapt to the temperature.
