All of the conditions surrounding an organism is called a(n) ______.
environment
Any substance that damages the environment is _____.
pollution
What hockey team has won the most Stanley Cups?

both begin with a producer
An attempt to preserve or protect an environment from harmful changes is called ________.
conservation
Which team won 4 Stanley Cups in a row?
New York Islanders
What is the source of energy for most plants?
sunlight
predator and prey
Which would cause an ecosystem to change quickly?
an earthquake

How many wins did the Boston Bruins have in the 2016-2017 regular season?
44
During photosynthesis plants give _______.

An organism that cannot makes its own food is called a(n) ________.
consumer
Non-native animal populations can grow rapidly in a new ecosystem because?
predators in the ecosystem are not used to hunting them
What are three other items that should not be placed in trash and dumped in landfills?
paint, chemicals, and plastic
What is Sidney Crosby’s nickname?
Sid the Kid
During cellular respiration, organisms give off _______.
carbon dioxide
Explain how producers, consumers, and decomposers all help an ecosystem support the population within it.
Producers turn sunlight into energy that is used in the ecosystem. Consumers eat producers and help keep local populations from getting too large. Decomposers break down dead organisms and wastes into material that can be used again by other organisms in the ecosystem.
Available supplies of food, water, sunlight, and space in an environment is called a(n) _________.
resources
Look carefully at the image. How is each population in the food chain affected if humans start using large amounts of pesticides in nearby areas?
Pesticides reduce the grasshopper population. The remaining grasshoppers have less competition for food and the trees would grow more because there would be fewer grasshoppers eating them. With fewer grasshoppers, lizards would have more competition for food and some might die. The same would then happen for birds that eat lizards, and then for foxes that eat birds.
When was the last time the Bruins won the cup?
2011
