This means primary producers become the starting point in the food chain for heterotroph organisms that do eat other organisms. Some marine primary producers are specialised bacteria and archaea which are chemotrophs, making their own food by gathering around hydrothermal vents and cold seeps and using chemosynthesis.
Lycaenidae is the second-largest family of butterflies (behind Nymphalidae, brush-footed butterflies), with over 6,000 species worldwide, [1] whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
While blooms can be studied and traced, scientists still do not know if the extra production gets incorporated into the food chain or falls to the deep ocean after a bloom dies off. [ 42 ] [ 43 ] Even if carbon is exported to depth, raining organic matter can be respired, potentially creating mid-column anoxic zones or causing acidification of ...
Lycaeninae, the coppers, are a subfamily of the gossamer-winged butterflies (Lycaenidae). The relationships of the Lycaenidae are not fully resolved. Sometimes the Polyommatinae and Theclinae are included in the Lycaeninae; in particular the Theclinae tribe Eumaeini contains many similar taxa. Consequently, the delimitation of the Lycaeninae is ...
The subfamily Theclinae is a group of butterflies, often referred to as hairstreaks, with some species instead known as elfins or by other names. The group is part of the family Lycaenidae, the "gossamer-winged butterflies".
