Mutualism

Front

A relationship between two species in which both species benefit

Back

Commensalism

Front

A relationship between two organisms of different species where one benefits and the other is neither harmed nor benefited

Back

predator-prey interactions

Front

an important process for transferring energy from one trophic level to the next.

Back

ATP

Front

(adenosine triphosphate) main energy source that cells use for most of their work

Back

threats to biodiversity

Front

habitat loss, introduced species, overharvesting, global change

Back

Biotic factors in an ecosystem

Front

living factors such as humans, plants, animals, and fungi

Back

Photosynthesis

Front

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 and starches

Back

Respiration

Front

The process by which cells break down simple food molecules to release the energy they contain.

Back

carbon cycle

Front

the movement of carbon from the nonliving environment into living things and back

Back

primary consumer

Front

An organism that eats producers

Back

competition

Front

the struggle between organisms to survive in a habitat with limited resources

Back

carrying capacity

Front

Largest number of individuals of a population that a environment can support

Back

Nucleotide

Front

monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base

Back

Parasitism

Front

A relationship between two organisms of different species where one benefits and the other is harmed

Back

Enzyme

Front

A type of protein that speeds up a chemical reaction in a living thing

Back

Succession

Front

(ecology) the gradual and orderly process of change in an ecosystem brought about by the progressive replacement of one community by another until a stable climax is established

Back

Decomposer

Front

an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

Back

pioneer species

Front

first species to populate an area during succession

Back

secondary consumer

Front

An organism that eats primary consumers

Back

food pyramid

Front

a model that shows the loss of energy from one trophic level to another; often called an ecological pyramid

Back

amino acids

Front

a simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.

Back

Ecosystem

Front

A biological community of interacting organisms and their physical environment.

Back

Consumer

Front

An organism that obtains energy by feeding on other organisms

Back

population graph

Front

A histogram showing the population structure of a country, also called an age-sex pyramid

Back

Producer

Front

An organism that makes its own food

Back

Bio molecules

Front

Organic molecules found in all living organisms e.g. lipids, carbohydrates and proteins.
