Obtaining Energy
This is a type of organism that captures energy (from the sun or chemicals) and provides energy for other organisms.
an organism that needs to eat or absorb nutrients from other organisms
consumer
This process uses oxygen and sugar and converts it into carbon dioxide and chemical energy (ATP)
cellular respiration
An organism, like bacteria or fungi, that absorbs energy by breaking down the remains of dead organisms or animal waste
decomposer
an organism that cannot make its own glucose and must feed or absorb other organisms to obtain nutrients.
heterotroph
a model showing a single path of energy flow and matter in an ecosystem
food chain
sun's light energy is converted into chemical energy for use by the cell
photosynthesis
a heterotroph that decomposes organic material and returns the nutrients to the soil, air, and water. An earthworm is an example.
detritivore
omnivore
A model that demonstrates many interconnected pathways through which energy and matter flow through an ecosystem.
food web
This chemical process uses carbon dioxide and water to produce glucose and oxygen
photosynthesis
matter cannot be created or destroyed is this law
law of conservation of mass
seaweed in the ocean is an example of
an organism that produces its own food (glucose)
producer
this process uses oxygen and glucose and produces water and carbon dioxide (ATP too)
cellular respiration
anything that takes up space and has mass
matter
