Weeds do produce oxygen through photosynthesis, the same process used by desirable plants. Like all green plants that contain chlorophyll, weeds absorb carbon dioxide, water, an...

An autotroph is an organism that can build its own food from inorganic substances using energy from light or from chemical reactions. Unlike animals, which must eat other organi...

science-environment

Primary producers—organisms that convert sunlight or chemical energy into organic matter—are the original source of energy and carbon for almost all food webs. By turning in...

Autotrophs in the rainforest are organisms that make their own food using light, water, and carbon dioxide, forming the base of every food web. In dense forests where shade and...

A producer in the food chain is an organism that makes its own food from inorganic sources, forming the base of nearly all energy flow in ecosystems. Often called autotrophs, pr...

Science & Nature

At the foundation of nearly every land-based food web are producers—organisms that convert sunlight into chemical energy. Shrubs are common components of many ecosystems, but...

Relationships

The relationship between photosynthesis and cellular respiration is easiest to see in their balanced chemical equations. Photosynthesis uses light energy to convert carbon dioxi...

A primary producer in the food chain is an organism that can manufacture its own food from inorganic substances, usually using light or chemical energy. By converting energy int...

Science & Education

An aquatic producer is any photosynthetic or chemosynthetic organism that forms the base of aquatic food webs by converting inorganic carbon into organic matter. In freshwater l...

science-biology

Organisms described as autotrophic can build their own organic matter from simple inorganic sources, using energy such as sunlight or chemical bonds. In most ecosystems, autotro...
