Carnivore

Omnivore

Food chain
A food chain is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species.
Food web
A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Energy pyramid
n ecological pyramid is a graphical representation designed to show the biomass or bio productivity at each tropic level in a given ecosystem.
Carrying capacity
the largest population that a movement can support at any given time
Prey
an animal that is hunted and killed by another for food.
Predator
an organists that eats all of the parts of another organism
Mutualism

- Parasitism
parasitism, relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.
Producers
Producers: Photosynthesizing organisms.
Decomposers
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life.
Tundra
In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons.
emperate deciduous forest
Temperate deciduous or temperate broad-leaf forests are a variety of temperate forest ‘dominated’ by trees that lose their leaves each year.
. Tropical rainforest
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season
Coniferous forest
Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature. Temperate coniferous forests are found predominantly in areas with warm summers and cool winters
Savanna
A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close
Temperate grassland
Temperate grasslands are areas of open grassy plains that are sparsely populated with trees.
