Not Spider Webs
a graphical image of what eats what in an ecosystem
food web
anything that has mass and takes up space
matter
conditions in an experiment are also called
variables
an animal that eats other animals is called a
carnivore
a type of living thing that recieves its energy from the Sun and is unable to move from place to place on its own
a plant
A type of organism that can break down most types of organic matter, can be large, small, or tiny pieces of mold
fungi
True or False: Plants do not need soil to grow, water and air are the most important matter for plant growth
TRUE : plants need mostly air and water. Some plants use soil for their roots to take hold and grow, but air and water are necessary for life.
Name two variables that can easily be changed to measure plant growth
sunlight levels
water levels
you would expect a carnivore to have teeth that look ________________
sharp
How do plants get their "food"
through nutrients in the soil
an organism that uses sunlight to make its own energy
producer
if we have a "drought" what can we expect to happen to the plants in our ecosystem
less water means lower growth
what are the 3 things we can do with variables in an experiment?
keep them the same
measure them
change them
animals that eat both animals and plants are called
omnivores
the process where plants use sunlight, water, and CO2 to produce sugar and release oxygen
photosynthesis
Where does the the plant at the start of the food web receive its energy from
the sun
describe an example of how matter changes throughout time
hint : think of a seed
example: seedling absorbs nutrients from ground and air and develops into a flower with a higher mass
the name of the variable that we measure in an experiment
dependent
an organism that consumes dead or non-living biomass with no need for internal digestion
decomposer
sunlight and air in plants are normally absorbed in what part of the plant?
leaves
On the food web shown in the other tab... who is the predator and prey of the mouse?
predator= lion
prey= plants
explain the difference between mass and matter
Matter includes all things present on earth and its atmosphere that takes up some space and has a definite mass.
Mass, on the other hand, is the quantity present inside the matter.
If Ms. Johnson was measuring how plants changed in response to different amounts of sunlight name label these variables as: Measured, Stayed the Same, Changed
Oxygen
Soil
Water
Sunlight
Plant Growth
Oxygen = same
Soil = same
Water = same
Sunlight = changed
Plant Growth = measured
herbivores, carnivores, and omnivores are all apart of a bigger class of organisms called ___________
consumers
If Ms. Nina was doing an experiment to see how sunlight affected plant growth how might she test this?
