Science Study Cards Here is a list of all the study cards we’ve made during the Ecosystems Unit. Make sure you have each one completed. You will need to turn in your completed cards to earn 2 points on the test. They are due on the day of the test- Thursday February 16th. Please also use these study cards to help you prepare for the Ecosystems Test! You should know and be able to explain each of the key vocabulary words identified on the cards. It’s Alive (GRREW) Plant Parts Ecosystem #1 Ecosystem #2 Life Cycles Adaptations and Inherited Traits It’s Alive! An organism (living thing) is alive if it does all of the following: G - Grows and develops through a life cycle R - Reproduces more of its species R - Reacts to changes in its environment E - Energy is taken in W - Waste is given off Plant Parts Roots – Absorb nutrients and minerals from the soil, Anchor the plant in the soil Stem – Carries water and food throughout the plant, Supports the plant Leaves – Absorb the sunlight that is used for photosynthesis to make food for the plant Flower – Produces the fruit where the seeds are held to produce new plants (reproduction) *Photosynthesis – The process of plants making food from sunlight and carbon dioxide Ecosystem #1 Producers – organisms that make their own food. They capture energy from sunlight, and use it in a process called photosynthesis. Example: Consumers – organisms that get energy by eating other organisms. Example: Decomposers – organisms that help to break down and decay dead organisms and the waste of living organisms. Example: Predator – a carnivorous animal that hunts, kills, and eats other animals in order to survive. Example: Prey – an animal that is caught, killed, and eaten by another animal for food. Example: Ecosystem #2 Types of Consumers Herbivores – eat only plants and plant products. Some examples are elephants, deer, insects, gorillas, and cows. Carnivores – eat other animals. Some examples are ladybugs, spiders, sharks, hawks, and owls Omnivores – eat both plants and animals. Some examples are crows, raccoons, coyotes, and most humans. Scavengers – animals that feed on the bodies of dead organisms. Some examples are vultures and hyenas. Adaptations & Inherited Traits Adaptation – Structures and behaviors that help organisms survive in their surroundings Inherited Traits – Traits that pass from parents to offspring Instinctive Behavior – A behavior that an animal inherits from its parents Structural Adaptation – A body part that does a certain job for an organism Behavioral Adaptation – A specific behavior that helps an organism survive that may or may not be inherited Learned Behavior – A behavior that an animal develops by observing other animals or being taught, not by inheriting it Life Cycle: the series of changes and stages of development that a living thing goes through Metamorphosis: a change in body form that occurs during the life cycle of certain animals (example: butterflies, frogs, dragonflies)
