Scientific study of interactions among organisms and between organisms and their environment.

Levels of Organization

Organism, population, community, ecosystem, biosphere.

Group of ecosystems that have the same climate and similar dominant communities.

A group of organisms so similar to one another that they can breed and produce fertile offspring.

An organism that can capture energy from sunlight or chemicals and use it to produce its own food from organic compounds; known as the producer.

Process by which plants and other organisms use light energy to convert water and carbon dioxide into oxygen.

When organisms use chemical energy to produce carbohydrates.

Organism that obtains energy from the foods it consumes; also known as the consumer.

Obtain energy by only eating plants.

Feed on plant and animal remains and other dead matter.

a series of steps in which organisms transfer energy by eating and being eaten.

Links all the food chains in an ecosystem together.

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

Each step in a food chain or web.

diagram that shows the relative amounts of energy or matter contained within each trophic level in the food chain or web.

Process in which elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

When an ecosystem is limited by a single nutrient that is scarce.

when an aquatic ecosystem receives a large input of limiting nutrient, an increase of algae and other producers are made.
