This text explores key interactions among living organisms, focusing on adaptation, competition, and predation. Natural selection drives adaptation, allowing species to thrive in their environments, illustrated by animals like penguins and cheetahs. Competition for limited resources leads to struggles for survival, as seen in warblers in pine forests. Predation showcases the dynamic relationship between predators and prey, emphasizing adaptation strategies like camouflage and mimicry that prey use to evade hunters. Understanding these interactions reveals the complexities of ecosystems and survival strategies in nature.
E N D
1. Adapting to the environment • Natural selection: process where a characteristic that makes an individual better suited to their environment becomes common. • Adaptation: behavior and/or physical characteristic that allows an organism to live successfully • Ex. Penguin, cheetah, finches
2. Competition: struggle between organisms to survive and obtain a limited resource. • Ex. Warblers in pine
Interaction in which an organism kills another for food • Predation can greatly effect population size • Too many predators causes a decrease in prey population which then causes a decrease in predators. • Predators/prey populations rise and fall in cycles 3. Predation
Predators have adapted to become better and more efficient • Ex. Hunting at night, speed, eyes in the front of their head • Prey have also adapted to avoid being eaten • Mimicry • False coloring • Warning colors • Camouflage
