Biology Semester 1 Final

A group of individuals that belong to the same species and live in the same area

A consumer in a biological community; An animal that preys on other animals

An interaction in which one organism kills another for food.

An organism that lives in or on another organism, deriving nourishment at the expense of its host, usually without killing it

Environmental factors that restrict population growth

nonliving parts of an ecosystem

(1). air

(2). water

(3). sunlight

(4). soil

(5). temperature

(6). climate

living parts of an ecosystem

plants, animals, fungi, bacteria

An organism that can make its own food.

incapable of photosynthesis and must obtain their energy by consuming other organisms

An organism that breaks down wastes and dead organisms

the maximum size of population the environment will support

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars

Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

6CO2 + 6H2O ------> C6H12O6 + 6O2

C6H12O6+6O2---> 6CO2+6H2O+ATP

Respiration that does not require oxygen

alcohol and lactic acid

Movement of molecules from an area of higher concentration to an area of lower concentration.

the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins

Energy-requiring process that moves material across a cell membrane against a concentration difference

Solute concentration is less than that inside the cell; cell gains water

Solute concentration is greater than that inside the cell; cell loses water

a solution whose solute concentration is equal to the solute concentration inside a cell
