Ecological Adaptation in the Animal Kingdom

This set of vocabulary flashcards covers the definitions and specific examples of structural, behavioral, and physiological adaptations in animals and plants based on the BIO 102 lecture by Dr. Excellence AKEREDOLU.

Ecological adaptation

The processes by which organisms adjust to their environment to enhance their survival and reproduction, involving changes in physical structure, behavior, or physiological processes.

Structural Adaptations

Physical characteristics that enhance an organism's ability to survive in its environment, such as camouflage and beak shapes.

Camouflage

A structural adaptation where an organism, such as a chameleon or Arctic fox, changes color to blend into its surroundings to avoid predators or ambush prey.

Darwin's finches

A group of birds that exhibit various beak shapes adapted for different diets like seeds, insects, or nectar, allowing them to exploit different ecological niches.

Behavioral Adaptations

Actions or behaviors developed by organisms that aid in survival, such as migration patterns and hibernation.

Migration Patterns

A behavioral adaptation where bird species travel thousands of miles to find food and favorable breeding conditions to avoid harsh climates.

Hibernation

A state entered by animals like bears during winter months to conserve energy when food is scarce.

Physiological Adaptations

Internal body processes that help organisms cope with environmental stresses, such as water conservation and thermoregulation.

Water Conservation

A physiological adaptation in desert animals like camels that allows them to minimize water loss and store water efficiently.

Thermoregulation

Internal processes, such as frogs changing skin color in response to temperature, that help organisms regulate their body heat.

Arctic Fox

A species adapted to cold climates with thick fur for insulation and a seasonal color change from brown to white for camouflage against snow.

Cacti

Plants adapted to arid environments with thick, waxy skin to reduce water loss and deep root systems to access underground moisture.

Biodiversity

The variety of life on Earth, which is significantly supported by adaptations that enable species to occupy various ecological niches.
