What is the definition of Net Primary Productivity?
Energy used in cellular respiration
Total amount of incoming solar energy
Total amount of chemical energy produced
The amount of biomass available to consumers
How is current climate change different from historical climate change?
It is not really different.
The rate of change is faster.
The concentrations of CO2 are higher than 400 ppm
the rate of change is faster and the concentrations of CO2 are higher than 400 ppm
If warming of the oceans causes a decline in NPP, then what type of feedback* will this produce
climate change? (Use "feedback" as defined by climate scientists)
Question 3 options:
negative feedback (because it will go slower)
positive feedback because it will be helpful.
positive feedback (because it will proceed faster)
negative feedback because it will be harmful.
Besides burning fossil fuels, which of the following is a major way that humans have contributed
to global climate change?
Question 4 options:
Adding calcium carbonate to the ocean
Deforestation
Emitting cloud-forming particles
Planting nitrogen fixing crops
, A tapeworm can survive inside the tissues of a pig, and be transferred to a human where it can
develop further and reproduce while stealing nutrients from its host. What species interaction is
this?
Question 5 options:
competition
Consumption
mutualism
commensalism
Why does bioaccumulation (or biomagnification) impact higher consumers in a food chain?
Question 6 options:
Higher consumers have higher productivity than their prey, and therefore they contain more
toxins.
With every step up a food chain, consumers have less biomass than their prey but
the same amount of toxins.
Higher consumers live in habitats that are exposed to more toxins.
Higher consumers are most sensitive to toxins. They can be affected at lower
concentrations.
Mycorrhizal fungi excrete enzymes that digest organic matter into nutrients in soil surrounding
plant roots, and they receive carbon (forms of sugar) from plants in return. What type of
interaction is this?
Question 7 options:
mutualistic
commensalistic
competition
Consumption
