100
What is an ecosystem?
Organisms working together in their physical environment.
100
What is the difference between biotic and abiotic?
abiotic means not living organisms and biotic means living organisms.
100
What are the two main types of adaptations
Behavioral and Physical Adaptations.
100
What is equilibrium?
The balance of populations in an ecosystem.
100
How does energy circulate through an ecosystem?
Through the consumption of organisms
200
What does a food web show?
Food Webs show the flow of energy
200
What is an abiotic and a biotic factor in this room?
biotic is a person and abiotic is anything else!
200
What are the three reasons that physical adaptations happen?
Adaptations to climate, adaptations for food consumption, and adaptations for avoidance of predators.
200
What happens when an ecosystem is out of equilibrium?
Organisms Adapt, migrate, or die.
200
What are two types of matter that could move through an ecosystem?
Nitrogen and Carbon
300
What are the three main types of organisms in a food web?
producer, consumer, decomposer
300
What is it called when the same species of organisms group together?
A population
300
How long does it take a species to adapt?
Over thousands of years or generations.
300
What is the difference between and testable question and a hypothesis?
A testable question is a questions that you can design and experiment around and a hypothesis is what you predict will happen in that experiment.
300
What is the main source of energy in any ecosystem?
The sun is the main source of energy for any ecosystem!
400
What in a food web show how the energy flows?
The arrows show which direction the energy is moving.
400
In an ecosystem, what is the difference between a community and a population?
Populations are all one type of species and a community is a group of populations living together.
400
Why is plastic pollution such a problem for ecosystems?
Plastic pollutions causes an imbalance in populations which causes the ecosystem to decrease needed populations.
400
What is a independent and a dependent variable?
An independent variable is one that the scientist changes and a dependent variable is the one that gets measured at the end.
400
What happens to energy as it moves up a food web by consumer levels?
The amount of available energy decreases.
500
Why do we need more producers than consumers in an ecosystem?
Producers have more energy and because energy decreases as you move up consumer levels. Also higher level consumers need to eat more organism to survive.
500
What is one ecosystem that could not survive without abiotic factors. Give an example
The ocean because those organisms can not survive with out water.
500
List three ways that plastic could be a problem for an ecosystem
Pollutes water which can decrease producers, cause all consumer levels to fluctuate, increases chemical levels that can move through food webs to people.

Jose wants to grow pea plants. He wants fins out which one will grow the tallest based on the amount of water he gives them. He puts one in the middle of the room, one in the window and one in the closet. He then gives each of his plants 10 ml of water every other day and records their growth. What is incorrect about his experiment?
His independent variable he is questioning is not the same one that he is testing in his experiment.
500
How does the circulation of matter differ from the circulation of energy?
Matter circulates through the soil and the air, where energy circles though consumption.
