Flashcards in Chapter 2 Deck (26):
Different species interacting
How do decomposers get their food?
By feeding on the dead
Occurs when organisms use the same limited resources
A close physical and long term relationship between two organisms of different species
A relationship between two organisms in which they both benefit
Relationship between two organisms is which one is not affected, and the other benefits
A relationship in which one (parasite) lives in/on the other (host). Host if harmed
One (predator) eats the other (prey)
What's a quadrat?
A method of deterring population size
Used on stationary animals
What is capture-recapture?
Method of deterring population size
Used on mobile animals
Formulae for capture-recapture
N1 ✖️N2 ➗M2
What is photosynthesis?
The process in which glucose is produced from water and carbon dioxide
Formula for photosynthesis
Carbon dioxide + water =======> glucose, oxygen, water
Where does photos occur?
What do chloroplasts contain?
Chlorophyll, green pigment
Formula for cellular respiration
Glucose, oxygen ======> carbon dioxide, water, energy
What is aerobic respiration?
How much energy is transferred in the flow of energy?
10%, 90% is lost
What is the carbon cycle?
The process of carbon dioxide cycled through an ecosystem by decomposers and photosynthesis
What is 'carrying capacity'?
The maximum of organisms in a population that can be sustained by an ecosystem
Buds beneath the bark that will grow into new branches after a fire has passed
Enhanced greenhouse effect
The burning of fuels that release gases into the air that trap heat, resulting in global warming
