  • Responses to the Environment
    The ability of organisms to detect and respond to changes in their environment
  • Behavioral mechanisms
    • Organisms can change their behavior in response to environmental cues, such as changes in temperature, light, or food availability
  • Physiological mechanisms
    • Involve changes in the activity of genes, enzymes, and hormones in response to environmental cues
  • Photoperiodism
    • The ability of plants to sense changes in the length of daylight and to use this information to regulate growth and development
  • Phototropism
    • The ability of plants to sense changes in the direction of light and to use this information to orient their growth
  • Taxis
    • The directed movement of an organism towards or away from a stimulus such as light, heat, or gravity
  • Kinesis
    • A non-directional response where an organism's speed or activity level changes due to changes in their environment
  • Nocturnal activity
    The behavior of animals that are active at night and sleep during the day
  • Diurnal activity

    The behavior of animals that are active during the day and sleep at night
  • Fight-or-flight response
    A physiological response to a perceived threat or danger, characterized by the release of adrenaline and other hormones
  • Predator warnings
    The communication of danger by one organism to others of the same species
  • Communication in organisms
    The transfer of information from one organism to another through signals or behaviors
  • Cooperative behavior
    Actions taken by organisms that benefit others in their group, often at a cost to themselves
  • Innate behaviors
    Behaviors that occur naturally without any need for learning, instinctual and present at birth
  • Learned behaviors
    Actions or behaviors that animals acquire through experience or observing others within their environment
  • Long-day plants
    Plants that flower when nights are short, typically blooming in late spring or early summer
  • Short-day plants
    Plants that require a long period of darkness (shorter daylight) in each 24-hour cycle to induce flowering
  • Mutualistic relationships

    Relationships where both organisms involved benefit from their interaction with each other
  • Natural selection
    The process where organisms possessing certain genotypic characteristics that make them better adjusted to their environment tend to survive, reproduce, and pass on these favorable genetic traits
  • Sympathetic nervous system
    The part of the autonomic nervous system that prepares the body for action by triggering the fight-or-flight response
