1. Principles of Biology
The study of life is called
What is biology?
Organisms that make their own food are called
What are producers/autotrophs
Cells that work together to perform a function form a
What is a tissue?
The process by which species change over time is
What is evolution?
he smallest unit of life is the
What is the cell?
The basic unit of structure and function in living things is the
What is the cell?
The role an organism plays in its environment is its
What is a niche?
Organs that work together to perform a major function form a
What is an organ system?
Darwin proposed the theory of evolution by
What is natural selection?
Living things interacting with their environment demonstrates
What is interdependence?
DNA carries the instructions fo
What are traits/proteins/heredity?
The relationship where both species benefit is called
What is mutualism?
The highest level of biological organization is the
What is the biosphere?
Traits that help organisms survive and reproduce are called
What are adaptations?
Groups of the same species living together in an area form a
What is a population?
Organisms maintain stable internal conditions through
What is homeostasis?
Organisms that cannot make their own food are called
What are consumers/heterotrophs?
The cell theory states that all living things are made of
What are cells?
Evidence for evolution comes from fossils, DNA, and
What is comparative anatomy (or embryology)
The survival of organisms with traits best suited to the environment is
What is natural selection?
The process by which organisms use energy to maintain life is
What is metabolism?
The interconnected feeding relationships in an ecosystem form a
What is a food web?
The levels of organization from smallest to largest are
What are cell → tissue → organ → organ system → organism → population → community → ecosystem → biosphere?
The idea that all living things share a common ancestor is called
What is common descent?
The total variety of life on Earth is called
What is biodiversity?
