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.
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.
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.
The microbial food web refers to the combined trophic interactions among microbes in aquatic environments. These microbes include viruses, bacteria, algae, heterotrophic protists (such as ciliates and flagellates). [1] In aquatic ecosystems, microbial food webs are essential because they form the basis for the cycling of nutrients and energy.
Being generally herbivorous, and mostly passive plankton-feeders, they live their lives according to the currents and find food by floating ventral-side up; some may more actively forage, at times. [3] They ensnare planktonic food by entangling it in a mucous web [8] measuring up to 5 cm wide—many times larger than their own bodies. If ...
The large blue (Phengaris arion) is a species of butterfly in the family Lycaenidae.The species was first defined in 1758 and first recorded in Britain in 1795. [2] In 1979 the species became mostly extinct in Britain but has been successfully reintroduced with new conservation methods. [3]
