Matter and Energy in Ecosystems I
air, water, and rocks are this type of matter
Non-living Matter
an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
Consumer
all the living and nonliving things interacting in a particular area
Ecosystem
True or False
Interdependence is when organisms help each other thrive. For Example, organisms exhale carbon dioxide which the plants use to produce oxygen.
True
When an organism hunts and eats other organisms it is called a?
Predator
The role a mushroom has in an ecosystem
Decomposer
an organism that gets energy storage molecules (such as glucose) by breaking down dead matter
decomposer
What do plants use to make sugar that is found in the air?
carbon dioxide
The part of a plant where gases enter and exit
Stomata
What is a hunted organism called?
prey
these two organisms cannot live without each other (they exchange gases)
plants and animals
List a living thing in an ocean ecosystem
fish, whale, plankton, sea weed
What is the part of a plant that gives them their color?

True - If they run out of water, they will die
Give an example of an omnivoire
humans, bears, birds, ...
the definition of matter
anything that has mass and/or takes up space
a molecule made of carbon and oxygen atoms; required by plants to perform photosynthesis
Carbon Dioxide
The fractional amount of energy one organism passes on to the next
1/10
Plants cannot grow too close together because ___________ need to spread out and absorb nutrients from the soil.
roots
The level of classification of an organism in the food chain that only eats producers.
First level consumer
matter that has life
Living things
Tell me a nonliving factor in a forest ecosystem
Rocks, soil, water,
the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
Photosynthesis
What is the differences between a plant and a mushroom
Mushrooms are decomposers, they feed off dead organisms, plants are producers, they feed off the sun and carbon dioxide.
herbivore
