Herbivores: organism that eats only plants
Carnivores: an organism that only eats meat
Omnivores: an organism that eats both plants and meat
Population: organisms that are the same species that live together
Community: Populations living in the same environment at the same time
Population density: groups of individuals belonging to the same species that live in the same region at the same time
Limiting factor: environmental factor that is of predominant importance in restricting the size of a population
Food chain: diagram that shows how food energy from 1 organism to another
Food web: a model that shows many different food chains in a web form
Predator: animal that feeds on other organisms
Prey: animals predators eat
Organism: is an individual living thing
Succession: A following of things, events, people, or ranks after another in sequence of time, as in a succession of disasters.

Taiga: a large naturally occurring area of land with largely evergreen forest vegetation found in northern sections of the Northern Hemisphere
Tundra: The tundra region is the coldest biome of the world. This region is treeless. Some vegetation like lichens, mosses and shrubs grows there. The winters are long and severely cold and the summers are cool.
Deciduous forest: A deciduous forest contains trees that lose their leaves each year. The leaves also change color. They turn red, orange, and yellow in autumn and then fall off. They grow back in spring.
Grasslands: Grassland biomes are vast stretches of grass where trees are rare. The soil of these ecosystems is very productive and so, they are used to grow crops like wheat and corn. Grasslands serve as grazing grounds for many animals.
Tropical rainforest: occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall.
Deserts: Deserts are located at the mid latitudes. They have extremely hot climates and less rainfall. The Sonoran desert is a rocky desert with Saguaro cacti and animals like snakes and lizards. The Sahara desert is a sandy desert having less or no vegetation.
Aquatic : Water is an aquatic resource that supports humans, animals, and plants. Freshwater and marine regions are aquatic ecosystems. All plants and organisms that live in these regions are aquatic.
