© A. Weinberg Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive.
© A. Weinberg We can separate adaptations into two categories: Physical AND Behavioral A D A P T A T I O N S
© A. Weinberg Physical adaptations are body structures. Some examples of physical adaptations are: Camouflage Mimicry Body coverings & parts Chemical defenses
© A. Weinberg Physical adaptations are body structures that allow an animal to find and consume food, defend itself, and to reproduce its species. Physical adaptations help an animal survive in its environment. Hey! I’m a walking stick. I look just like a stick you’d find on the ground. © A. Weinberg
Physical adaptation Camouflage (use of color in a surrounding) The chameleon can change its color to match its surroundings. Can you do that?
© A. Weinberg Mimicry (looking or sounding like another living organism) The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart? Poisonous Not poisonous Physical adaptation I’m the Monarch! I’m the Viceroy!
© A. Weinberg Chemical defenses (like venom, ink, sprays) Physical adaptation
© A. Weinberg Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth) Physical adaptations The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick things up.
© A. Weinberg Now let’s learn about Behavioral Adaptations… Behavioral Adaptations allow animals to respond to life needs. Each organism has unique methods of adapting to its environment by means of different actions.
© A. Weinberg Instinctive behaviors happen naturally & don’t need to be learned = Finding shelter Methods of gathering & storing food Defending oneself Raising young Hibernating Migrating
© A. Weinberg Learned behaviors Obtained by interacting with the environment and cannot be passed on to the next generation except by teaching. Give an example of a learned behaviour =
© A. Weinberg Natural Selection Natural Selection is a process that favours the survival of organisms with traits that make them survive their environment. In terms of adaptation, explain this statement using this picture
© A. Weinberg Explain both how and why these organisms have coevolved
© A. Weinberg Competition Competition leads to Competitive Exclusion: only one species can live in a specific niche because competition for resources will result in either a species going into extinction or extirpation OR evolving
© A. Weinberg Competition When two organisms try to use the same resource or niche, the best adapted one will succeed. Interspecific competition occurs between two different species Intraspecific competition occurs between the same species
© A. Weinberg Decreased Competition can also be a result of Resource Partitioning where different species coexist in a similar habitat but use different parts of a resource
© A. Weinberg Adaptive Radiation- when a species adapts and evolves to fill slightly different niches Competition can also promote Adaptive Radiation- when a species adapts and evolves to fill slightly different niches.
