ACT Science - Animal Life and Evolution

an animal that primarily feeds on insects or other small invertebrates

(of plants or animals) feeding on the meat or flesh of other animals

(of an animal) solely feeding on plants

an organism that cannot produce its own food and must obtain energy by consuming other organisms or organic matter

an organism that breaks down and feeds on dead organic matter, such as decaying plant and animal material

relating to organisms that live on or inside other organisms, benefiting at the expense of their hosts

(of an animal) generating and regulating their own body heat internally

the process of waking up or becoming active and alert, often influenced by environmental stimuli or internal biological rhythms

(of some animals or plants) to spend the winter sleeping deeply

a toxic substance produced and secreted by certain animals, typically used for defense or hunting

the harmful effects or potential for harm caused by a substance to living organisms or the environment

the capacity or ability of an organism, often referring to its genetic potential, reproductive success, or influence within its environment

the natural environment in which a particular animal, plant, or other organism normally lives or grows

(of wild animals) hunting, killing, and feeding on other animals for survival

a community of living organisms together with their physical environment, interacting as a system

primarily active or occurring during the daytime

(of animals or organisms) primarily active during the night

(of an animal) active during the twilight hours of dawn and dusk

to bring up partially digested food from the stomach back into the mouth, often to feed young or as part of the digestive process

the internal bony structure of an animal that gives it form and supports its weight

the hard outer covering that supports the body of an animal, such as an arthropod

(of an animal, plant, etc.) not having any living members, either due to natural causes, environmental changes, or human activity

the process of bringing extinct species back to life through scientific methods

(of a wild animal) tamed and adapted to live with or to the benefit of humans

the protection of the natural environment and resources from wasteful human activities

the scientific process of creating an identical or near-identical copy of a living organism, cell, or DNA sequence through asexual reproduction or genetic engineering techniques

related to evolution or the slow and gradual development of something

(biology) a distinct group within a species, often formed by geographic separation and showing slight physical or genetic differences

belonging to an early stage in the evolutionary development of humans or animals

(of an animal, plant, etc.) being at risk of extinction

found or restricted to a specific geographic region or habitat

an extinct large, elephant-like mammal with long, curved tusks and a body covered in hair, which lived during the Pleistocene epoch

an extinct hominid species closely related to modern humans, characterized by a robust build and distinctive facial features, that lived in Europe and parts of Asia until approximately 40,000 years ago
