Ecosystems, Food Chains + Food Webs
Vocabulary Activities
by Tom Wier
This three page set of vocabulary worksheets includes a crossword
puzzle, a wordsearch puzzle, and a “Crack the Code” brain teaser.
Each of the worksheets is based on the key terminology for the life
science food chain and food web unit that is a part of many state
standards.
Each worksheet reinforces the following sixteen terms:
pollution
non-living things
consumer
habitat
decomposer
food chain
scavenger
ecosystem
food web
prey
omnivore
predator
carnivore
herbivore
population
producers
photosynthesis
Each worksheets includes kid-friendly graphics to make it more
appealing. I also have an Ecosystem Bingo activity that is based on
many of the same words and concepts.
