LIVING:NON-LIVING:

 Ecology - the study of the interactions of organisms with one another and with their environment.  Ecologist – a scientist who studies ecology



 Biotic factors ◦ The living parts of an ecosystem  Ex.: plants, animals, fungi, bacteria ◦ Bio = living; life  Abiotic factors ◦ The nonliving parts of an ecosystem  Ex: water, sunlight, oxygen, temperature, soil ◦ A = non; not; without ◦ Bio = living; life

 Single living thing

 A group of individuals of the same species that live together.

 All the different populations of species that live together in an area –or-  All of the living things (biotic factors) in an area

 Made up of all the living and nonliving things (biotic and abiotic factors) that interact in a particular area ◦ Examples: prairie, mountain stream, ocean, forest

 In an ecosystem, organisms live in a habitat. ◦ Habitat provides food, water & shelter ◦ A single ecosystem may contain many habitats.  Within an ecosystem, organisms fit into a niche. ◦ Role or job within the ecosystem

 A large region with a similar climate, and specific plant and animal communities based on that climate Terrestrial (Land)Aquatic (Water) Tropical rainforestMarine (oceans) Savanna/GrasslandFreshwater (rivers & lakes) Temperate ForestEstuary Desert Taiga Tundra Mountain

 The part of Earth where life exists ◦ The biosphere includes the top portion of Earth’s crust, all the waters that cover Earth’s surface, and the atmosphere that surrounds Earth.
