Carbon Cycle
Process that absorbs atmospheric carbon, turning it into chemical energy stored within plants
Photosynthesis
The third level up from the bottom of the energy pyramid
Secondary Consumers
Outputs of photosynthesis
Oxygen and Glucose
Inputs of cellular respiration
Oxygen and glucose
Keystone species
Process of fossil fuels burning, returning carbon into the atmosphere
Combustion
Amount of energy that is available to move up to the next trophic level
10%
Inputs of photosynthesis
Carbon Dioxide, Water, Sunlight
Outputs of cellular respiration
Carbon dioxide, water, ATP
Name for the phase of life when a salmon hatches out of egg but still feed of attached yolk sack
Alevin
Definition of the Law of Conservation of Matter
Matter can not be created of destroyed (it can only change form)
Arrows represent this on a food web
The direction energy is moving. Points toward the organism that does the eating.
Chlorophyll
True or False:
Cellular respiration is a year round process that occurs through all 4 seasons.
True! Does not rely on access to sunlight like photosynthesis
Term for salmon reproduction
Spawn
Process done by plants and animals that releases carbon dioxide into the atmosphere
Cellular respiration
True or False:
Producers are autotrophs.
True! Producers make their own food through the process of photosynthesis
Organelle where photosynthesis occurs in the cell
Chloroplast
Organelle where cellular respiration occurs in the cell
Mitochondria
How do salmon move nutrients from the ocean to high altitude forests?
By swimming upstream to return to their natal stream where they will spawn and then die, allowing the nutrients from their bodies to be absorbed by nearby trees
Process done by fungi that breaks down organic matter, returning carbon to the soil
Decomposition
All energy enters the ecosystem from where?
The sun!
Reason for tree leaves changing color in the fall
Chlorophyll breaks down to save energy exposing other pigments like carotenoids (orange/yellow) and anthocyanin (red/purple)
True or False:
Only animals do cellular respiration
False! All living organisms do cell respiration to produce ATP in order to survive (Plants, animals, fungi, bacteria!)
Two key nutrients salmon help cycle through the ecosystem
Nitrogen & Phosphorous
