Name: _____________________________ Date: __________________ Ecosystem Study Guide Test Date: _______________________ Your child should be able to understand and work with the following words from our Ecosystem Unit: Carnivore – an animal that eats only other animals Herbivore – an animal that eats only plants Omnivore – an animal that eats both plants and other animals Predator – an animal that hunts other animals for food Prey – the animal being hunted as food Adaptation – special characteristics that help an organism survive in its environment Camouflage – an adaptation that allows an organism to blend in with its surroundings Mimicry – when an animal imitates the color or the shape of another organism Habitat – the home of a living thing Community – all the living things in an ecosystem Ecosystem – all the living and nonliving things Population – a group made up of only one kind of organism Producers – something that makes its own food (plant) Consumer – something that eats producers or other consumers for energy • Students should be able to label a given pair of organisms as predator or prey. (For example: Given a lizard and hawk: lizard – prey…..hawk – predator.) • Students should be able to compare and contrast characteristics of various ecosystems: -desert (dry, little rain, can be hot or cold) - forest (lots of trees, two kinds – temperate and tropical) - grassland (not a lot of trees, don’t get too much or too little rain lots of herbivores live there) - arctic (little rain or snow, cold winters and cool summers, part is always frozen) • Students should be able to explain the importance of the sun in the food chain. (The sun provides the producers with the energy needed to make their own food.) • Students should be able to explain why a food chain begins with a producer. (Producers use the energy from the sunlight to make their own food. Then a consumer gets its energy by eating the producer. Those consumers are eaten by another consumer to meet its energy needs, and so on. If there were no producers, everything else would die.) • Students should be able to give an example of a specific animal’s adaptation and describe how that adaptation helps the animal to survive. (For example, a bull frog has eyes on the top of its head to allow the frog to lookout for danger without leaving the water. Its adaptation is the position of its eyes to help keep it safe from predators.) • Students should be able to create and explain a simple food chain. sun algae mosquito dragonfly fish raccoon • Students should be able to explain the effect of removing an organism from a given food chain. (The organism that is below it will increase because there is no longer a predator. The population of the organism above it will decrease because its food source has gotten smaller.)
