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 pyrmind
An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Carrying capacity

Prey
an animal that is hunted and killed by another for food.
Predator
an animal that naturally preys on others.

Desert
an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year.
Tundra
a cold and treeless plain where harsh conditions make it hard for plants and animals alike to survive
Temperate deciduous forest
a biome that is always changing
Tropical rainforest
mainly located between the latitudes of 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn)
Coniferous forest
vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas that have long winters and moderate to high annual precipitation
Savanna
a grassy plain in tropical and subtropical regions, with few trees.
Temperate grassland
areas of open grassy plains that are sparsely populated with trees
