Autotroph

•Any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy

Producer

are responsible for the production of organic compounds from atmospheric or aquatic carbon dioxide.

Photosynthesis

The synthesis of complex organic material using carbon dioxide, water, inorganic salts, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll and other accessory pigments

Chemosynthesis

Process by which some organisms, such as certain bacteria, use chemical Energy to produce carbohydrates

Heterotroph

An organism that is unable to synthesize its own organic carbon-based compounds from inorganic sources, hence, feeds on organic matter produced by, or available in, other organisms

Consumer

An organism that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food from inorganic sources; a heterotroph

Herbivore

An animal that consumes herbaceous vegetation. Any animal that feeds chiefly on grass and other plants; horses are herbivores; the sauropod dinosaurs were apparently herbivores

Carnivore

An animal or plant (particularly insect- and invertebrate-eating plants) that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging

Omnivore

An animal that feeds on both plants and animals to survive

Detritvore

An organism that feeds on detritus or organic waste.

Decomposer

ecology) An organism whose ecological function involves the recycling of nutrients by performing the natural process of decomposition as it feeds on dead or decaying organisms

Food Chain

A feeding hierarchy in which organisms in an ecosystem are grouped into trophic (nutritional) levels and are shown in a succession to represent the flow of food energy and the feeding relationships between them

Food Web

interconnecting food chains in an ecological community

Trophic Level

A position in a food chain or Ecological Pyramid occupied by a group of organisms with similar feeding mode.

Ecological Pyramid

A graphical representation in the shape of a pyramid to show the feeding relationship of groups of organisms, and the flow of energy or biomass through the different trophic levels in a given ecosystem

Biomass

The total mass of all living material in a specific area, habitat, or region
