Characteristics and Life Processes of Living Things

Sunlight intensity = Abiotic factor Predator-prey interactions = Biotic factor Temperature range = Abiotic factor Competition for resources = Biotic factor

Thick fur for insulation = Cold climate Camouflage for hiding from predators = Predator-rich environment Cactus spines to conserve water = Arid desert Strong roots for stability in windy conditions = Exposed mountain slopes

Photosynthesis = Organism obtains nutrients from the environment Decomposition = Organism alters the environment Respiration = Organism obtains nutrients from the environment Nesting in trees = Organism alters the environment

The fundamental unit of life that performs vital functions.

All chemical reactions in an organism, including synthesis and breakdown of molecules.

The process of creating new organisms, either asexually or sexually.

The ability to maintain a stable internal environment despite external changes.

Gradual changes in a population to better suit the environment over generations.

The movement of energy through an ecosystem from producers to consumers.

The organization of living things into hierarchical levels based on characteristics.

The variety of forms, functions, and habitats exhibited by living things.

The variety of life forms in different environments on Earth.

An organism's specific role or function in its ecosystem.

The process where organisms with favorable traits are more likely to survive and reproduce.

The gradual change of species over time through adaptation and natural selection.

Abiotic factors are non-living components, while biotic factors are living components of an environment.
