Science of Curiosity TOPIC 2.6 Adaptations ENDURING UNDERSTANDING ERT-2 Ecosystems have structure and diversity that change over time. LEARNING OBJECTIVE ERT-2.H Describe how organisms adapt to their environment. ESSENTIAL KNOWLEDGE ERT-2.H.1 Organisms adapt to their environment over time, both in short- and long- term scales, via incremental changes at the genetic level. ERT-2.H.2 Environmental changes, either sudden or gradual, may threaten a species’ survival, requiring individuals to alter behaviors, move, or perish. Circle the TRUE word or phrase that completes each sentence: When the environment changes a (population / individual) can adapt to the new environment. An individual organism (chooses / is born with) genetic traits that may or may not be helpful in a given environment. Species who reproduce (asexualy / sexually) have offspring with more variation. A species (may or may not / will always) eventually adapt to a new environment. Part of the theory of evolution centers around the fact that organisms will produce more offspring than will survive, and that each of those offspring will have a different combinations of traits. In your own words, explain how these two facts lead to adaptation of a population. Use this scenario to explain:
