Food web
A food web (or food cycle) is a 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. To maintain their bodies, grow, develop, and to reproduce, autotrophs produce organic matter from inorganic substances, including both minerals and gases such as carbon dioxide. These chemical reactions require energy, which mainly comes from the Sun and largely by photosynthesis, although a very small amount comes from hydrothermal vents and hot springs.
Trophic level
The trophic level of an organism is the position it occupies in a food chain. The word trophic derives from the Greek τροφή (trophē) referring to food or nourishment. A food chain represents a succession of organisms that eat another organism and are, in turn, eaten themselves. The number of steps an organism is from the start of the chain is a measure of its trophic level. Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web".
Origin of the domestic dog
The origin of the domestic dog is not clear. The domestic dog is a member of the genus "Canis", which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the extant gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.
Predation
In an ecosystem, predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on it, but the act of predation often results in the death of the prey and the eventual absorption of the prey's tissue through digestion. Predation is often, though not always, carnivory, one of several heterotrophic consumer-resource interactions. Different feeding behaviors such as parasitism, parasitoidism, micropredation and predation form a continuum rather than being entirely separate strategies.
Forage fish
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the family Clupeidae (herrings, sardines, shad, hilsa, menhaden, anchovies and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin, and the goldband fusiliers pictured on the right. Forage fish compensate for their small size by forming schools.
Nile crocodile
The Nile crocodile ("Crocodylus niloticus") is an African crocodile, the largest freshwater predator in Africa, and may be considered the second largest extant reptile in the world, after the saltwater crocodile ("Crocodylus porosus"). The Nile crocodile is quite widespread throughout Sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent and lives in different types of aquatic environments such as lakes, rivers and marshlands. Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes.
Martial eagle
The martial eagle ("Polemaetus bellicosus") is a large eagle native to sub-Saharan Africa. It is the only member of the genus "Polemaetus." A species of the booted eagle sub-family ("Aquillinae"), it has feathering over its tarsus. One of the largest and most powerful species of booted eagle, it is a fairly opportunistic predator that varies it prey selection between mammals, birds and reptiles. Its hunting technique is unique as it is one of few eagle species known to hunt primarily from a high soar, by stooping on its quarry. An inhabitant of wooded belts of otherwise open savanna, this species has shown a precipitous decline in the last few centuries due to a variety of factors.

Carnivores are meat eaters right?
