1 Interactions Among Living Things How do adaptations help an organism survive?What are competition and predation?What are three types of symbiosis?
2 My Planet Diary- Reading Prompt Discuss the questions on your packet with your row neighbors. Answer them on the spaces provided.1. How does the trap-jaw ant’s adaptation help it avoid becoming prey for another organism?2. What are some adaptation other predators have to capture prey?
3 How do adaptations help organisms survive? Adaptations are special features or abilities to help an organism escape danger or catch its food.Examples:Camouflage - Hide from predator or preyWarning coloration - Bright colors let predators know you are poisonous.Biolumenesence - A flash of light often produced by bacteria in another animal.
8 NichesAll organisms have a role they play in the environment. This role is called a niche.This role explains:How an organism obtains food and shelter, finds a mate, cares for its young and avoids danger.
9 Competition Vs. Predation Two members of the same species might occupy the same niche. This can be a reason for Competition. This causes a struggle for survival as they both attempt to use the same limited resources.Predators catch and eat other organisms (prey) for nutrients and survival. This interaction of feeding is called Predation.
12 Activity: Making Models Imagine an ideal predator to capture and eat a porcupine. Draw or describe this new creature and its adaptations to protect itself from the porcupine while trying to feed on it.
13 Symbiotic Relationships Mutualism- Both organisms benefit from the relationshipCommensalism- One organism benefits and one organism is not affectedParasitism- One organism benefits and one organism is harmed
