Biodiversity
What is Biodiversity?
The sum of all living organisms in an ecosystem.
What is a food web?
a system of interdependent species based on energy transfer between trophic levels
What are producers?
autotrophic organisms (produce their own energy)
ie. plants via photosynthesis
What is an Autotroph?
Organism that produces its own food (ie. via photosynthesis)
What is ecosystem diversity?
# of different ecosystems in an area
What does a food pyramid do?
helps illustrate food webs hierarchically (in tiers)
What are primary consumers?
herbivores that consume the producers
What is a Hetorotroph?
Organism that consumes other organisms as food
What is species diversity?
# of different species in an ecosystem
What are herbivores
Animals that eat producers only
What are secondary consumers?
carnivores or omnivores that consume primary consumers and producers
What is a Decomposer?
organisms that consume dead organic matter and/or waste.
What is genetics diversity?
level of diversity in heritable traits within a species
What are Carnivores?
Organisms that eat consumers only
What are Tertiary consumers?
consumers that consume secondary consumers, etc.
Energy moves in one direction? (True or False)
True
Equation for Biodiversity?
Higher biodiversity = more resilient against change!
What are omnivores?
Organism that eat consumers and producers
When energy is passed up the trophic level does it lose energy or gain?
Lose.
If a rabbit starts of with 4000, then a snake eats the rabbit, then the snake gets eaten by the hawk. How much energy would the hawk get than
40.
