ABIOTIC & BIOTIC Key Vocabulary: -Ecosystem -Biotic -Abiotic Factors
BIOSPHERE The Biosphere is one of Earth’s 4 Systems: 1. 2. 3. 4. Lithosphere Hydrosphere Atmosphere Biosphere None of the Earth’s systems are INDEPENDENT, instead they are INTERDEPENDENT
BIOSPHERE The biosphere is: • the portion of Earth that supports living things • unique to Earth • dependent on the other Earth Systems
What is the scientific way to say “living”? Biotic Factors- all living things in an ecosystem, such as plants, animals, fungi, & microorganisms
What is the scientific way to say “non-living”? -Abiotic factors are all of the nonliving things in an ecosystem. -The abiotic factors in an ecosystem include: water, soil, temperature, air, wind, elevation, source of energy (usually the Sun).
ECOLOGICAL LEVELS: • Organism: one living thing • ex. lion • Population: group of organisms of the same species living together ex. A pride of lions
ECOLOGICAL LEVELS: • Community: collection of interacting populations ex. Lions and hyenas • Ecosystem: organisms and their physical : surroundings ex. Lions, hyenas, water, sun
HABITAT • A HABITAT: is the place where an organism lives out its life • Examples include the bottom of a stream, a maple tree, a pond, a park • A habitat can change due to natural and human causes
ECOSYSTEMS • The biosphere’s systems are called: ECOSYSTEMS • All ecosystems must have a constant source of energy (usually the sun) and cycles to reuse raw materials. • Examples are the water, nitrogen cycle, oxygen. CO 2 cycle • An ecosystem is made up of all the LIVING and NON-LIVING components in a given area.
What are the essential parts to all ecosystems? An ecosystem is all of the living and non-living things in an area.
HABITATS: • Terrestrial: • Aquatic: land water • marine: salt water • estuary: where fresh and salt water mix • Niche: role a species plays in a community
