Study Notes

Thermoregulation in Animals

Some animals bathe to cool down
Flying insects, such as bees, use shivering to warm up before taking flight
Adjusting metabolic heat production is a way for animals to regulate body temperature

Behavioral Adaptations

Some animals, like hummingbirds, enter a state of inactivity, such as seeking shelter, during extreme periods of weather or when food is scarce
Inactivity helps animals conserve energy and survive during harsh conditions

Communication in Animals

Pheromones are chemical substances released by an individual to affect other individuals of the same species
Pheromones are used for communication, such as to bring about mating or other behaviors

Territorial Behavior

Territories are used for feeding, mating, and rearing young
Territories are fixed in location and help animals defend their resources and space
