Ecosystems and Environment
A group of the same species in an area
Population
Which is the consumer in this situation: Zebras or Lions?
Zebras
The living and nonliving things interact with each other in an area.
Ecosystem
What are molecules that store energy called?
Energy storage molecules
What population is the one that eats other organisms?
Consumer population
fat, glucose (sugar), starch (carbohydrates)
A living thing
Organism
What happens to an animal when their food source decreases in numbers?
What is the name of the population in an ecosystem that is eaten?
resource population
Weebugs eat greenleafs. What happens to the weebugs if the greenleaf population increases?
Weebugs get more ESMs to reproduce which yields more births and a growing population
When something stays relatively the same over time.
stability
How do consumers gain energy?
By consuming other organisms
What population that gets its energy from photosynthesis called?
producer
greenleaf -> weebug -> furbil
What happens to the greenleafs and furbils if a disease dramatically decreased the weebug population.
Greenleaf population increases because the weebugs aren't eating it anymore
Furbils decrease because they don't have food for ESMs to reproduce
The capacity to do work or cause change
energy
Which population receives the least accumulated energy?
The apex predator
What happened when wolves were re-introduced to Yellowstone National Park? List at least 3 events.
more grass
defined rivers
resurgence of many animal species: birds, beavers, etc.
What happened to the orca population when the seals were weighing 75% of their normal weight? Why?
Orca population decreased because not as much energy from ESM(fat) for reproduction. Less births.
the technique we used to estimate the number of pinto beans in our lunch bag ecosystem.
mark and recapture sampling
Give 3 examples in the animal kingdom of how reproduction requires A LOT of energy
salmon
emperor penguins
elephant seals
fireflies
