Ecosystem Flashcards
Photosynthesis
a process where plants use water,sunlight and carbon dioxide to make glucose
chloroplast
a plants organelle that photosynthesis takes place in
Carbohydrates
sugar molecules or food
chlorophyll
a green pigment in plants leaves
cellular respiration
process where organisms use oxygen to break down food,sugar,to produce energy
producer
an organism that makes their own food
autotrophs
producer
consumers
organisms that get their energy by eating other organisms
heterotrophs
consumer
herbivores
plant eaters
carnivores
meat eaters
omnivore
eaters of everything
decomposers
consumers that get their food by breaking down dead organisms
food chain
a sequence where energy is transferred from one organism to the next as each organism eats another organism
food web
a diagram that shows many feeding relationships in a ecosystem
how is energy transfered
plants uses energy from sunlight to make sugar and then is then passed on to consumers
trophic level
each step in the transfer of energy through a food chain or food web
describe one way consumers
cows need to eat grass to get energy
list two types of consumers
primary consumers,cow,and secondary,lion.
