A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community.Another name for food web is consumer-resource system.Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs. with large plants such as mangroves, seagrass and rushes. Trophic levels in the Ria de Aveiro food web were consistent with previous reports on the studied species (Marin-Guirao et al., 2008, Pasquaud et al., 2010), and allowed to discriminate between species that while occupying similar habitats, have distinct feeding tactics, such as the case of the two sediment dwellers, S. plana and H. diversicolor.

Detritus is eaten Simplified feeding relationships are shown in this Curious Minds is a Government initiative jointly led by the Ministry of Business, Innovation and Employment, the Ministry of Education and the Office of the Prime Minister’s Chief Science Advisor. The sun gives energy to the plants by a process called photosynthesis, in which the plants converts carbon dioxide and water into oxygen and glucose. With the help of my partner Jay-Don I had created a food web of my own using some of the photos I … All organisms need energy to live. In some regions of the San Francisco Estuary, the two broad habitat types, tidal wetland and open water, contain distinct trophic pathways that function separately and in parallel (Grimaldo et al. then become food for snails and shellfish. b.
