Dependent variable
What you’re measuring (u axis)
Independent variable
What you’re changing (x axis)
1 constant

Control
Opposite of independent variable, non treated group.
If part of a hypothesis is independent variable then part is the __________?
Dependent variable
How does energy flow in an ecosystem?
In 1 direction, from producers ▶️ consumers ▶️decomposers
What is a short term effect?
Immediate result of an event like the fish population rising quickly because they aren’t sharks
Long term effect?
Takes time to show like the fish population reaching its carrying capacity.
Decomposers?
Recycled energy by eating dead organisms.
What factors can influence population growth?
Hunting, amount of food, disease, predators, exit.
What is the role of producers?
To produce energy through photo synthesis is which takes light energy and turns it into oxygen and chemical energy (sugar for the plant to eat).
Logistic growth?
Steady until reaching carrying capacity
