The study of interations between biotic and abiotic components in an ecosystem

Ecosystem A complex, self-regulating system in which living things interact with each other and non-living things. Ecosystems come in all sizes and are made up of different biotic and abiotic characteristics.
Healthy ecosystems have... An energy source, definite boundaries, biodiversity, nutrients, minerals, water, etc.
Biodiversity a variety of different organisms with different roles in an ecosystem.
Sustainable populations of plants, animals and other living organisms can continue to interact and reproduce indefinitely. Sustainability helps support future generations.
Stewardship A way of acting that involves taking personal responsibility for the management and care of something. For example: the environment
Species group of organisms that can reproduce with each other, and their offspring are viable.
Community populations of different species live and interact in an area where an organism lives.
Niche an organisms role in an environment.
Biomes large geographical area that contains similar ecosystems. Categorized by average rainfall, temperature and plants.
how many biomes are in Canada.. there are 5 terrestrial biomes in Canada and 2 aquatic biomes. Ecosystems combine to make biomes. Biomes combine to make the atmosphere.
Marine Biomes marine biomes are found within the ocean, and have a high salt content.
Fresh water Biomes fresh water biomes are found within the lakes, streams, rivers and wetlands, and have a low salt content.
Atmosphere (Air) layers of gases that surrounds the earth. it contains water, carbon dioxide, oxygen, Ozone, etc. the atmosphere help keep the plants warm.
Lithosphere (Ground) earths solid outer layer, includes the rigid crust and upper mantle. It runs 100km down from the surface. It also includes soil.
Hydrosphere (Water) ALL of the water on earth. 97% of this water is salt water in the earths oceans. all living things depend on water for survival.
What sustains life on earth? Solar energy, the cycling of matter, and gravity.
Organic Substances contains atoms of C.H. and many times O.N. (for example: proteins, sugars, fats)
Inorganic Substances matter does not contain carbon and H (hydrogen) atoms (For example: nylon, carbon dioxide)
Decay Organic minerals die, and then decomposers break them down and then recycle nutrients back to the earth.
Decomposers (mushrooms, bread mold, bacteria, fungi) break down organic matter into small inorganic molecules.
