What is an autotroph?
How much energy is moved forward from one trophic level to the next?
Diffusion moves from?
What is an area of high concentration to low?
pH below 7
What is an acid?
pH of purified water
What is 7.0?
An organism that consumes other living things for energy and nutrients
What is a heterotroph?
If there are 1500 kcal available in the autotroph level, how much energy is available to the primary consumer?
What is 150 kcal?
Diffusion of water through a cell membrane is called?
What is osmosis?
pH above 7
What is a base?
The part of sea urchins that is destroyed by ocean acidification
What is the shell?
When one organism hunts and kills another for food
What is predation?
In our oceanic food web, what plant was affected when sea otters were removed?
What is kelp?
This image shows molecules that are in and out of a cell. How will the molecules move?
What is into the cell?
The effect of pH on sea urchins (or other calcium-shelled organisms)
What is shell damage/shell loss?
The numerical value (pH) of something that is acidic
What is less than 7?
The organism that consumes secondary consumers
What is a tertiary consumer?
Where the greatest number of organisms /biomass should be in a food pyramid
Movement across the cell membrane that does not require energy?
What is passive transport?
The effect of excess carbon dioxide in ocean water
What is ocean acidification?
A nonliving thing in an ecosystem
What is an abiotic factor?
A species on which other species in an ecosystem largely depend.
What is a keystone species?
Where the fewest number of organisms are in a trophic pyramid
What is the top level?
Does passive transport use ATP to move molecules against their concentration gradient?
What is no?
maintaining balanced internal conditions
What is homeostasis?
This organism will eat both plants and animals
What is an omnivore (or possibly a second order consumer)?
