Some of the things that Living things need are
1) Biotic: Living/once living (Food)
2) Abiotc: Nonliving (water)

Ecosystems and Biomes
Levels of OrganizationThe smallest level of organization is a single organism, which belongs to a population that includes other members of its species.

The Water Cycle
- Cycles of Matter
The processes of evaporation, condensation, and precipitation make up the water cycle.

The Carbon and Oxygen CyclesIn ecosystems, the processes by which carbon and oxygen are recycled are linked. Producers, consumers, and decomposers play roles in recycling carbon and oxygen.

The Nitrogen Cycle
- Cycles of Matter
In the nitrogen cycle, nitrogen moves from the air to the soil, into living things, and back into the air.

Ecosystems and Biomes
Deciduous Forest BiomesMany of the trees in the deciduous forest are deciduous trees, which shed their leaves and grow new ones each year. A deciduous forest receives at least 50 centimeters of precipitation each year. Temperatures vary greatly through the year.

Ecosystems and Biomes
Boreal Forest (Tiaga) BiomesMost of the trees in the boreal forest are coniferous trees, trees that produce their seeds in cones and have leaves shaped like needles. Winters in the boreal forest are cold and very snowy, but summers are warm and rainy enough to melt all the snow.

TundraThe tundra is an extremely cold and dry biome. Most of the soil in the tundra is permafrost, which is frozen all year.

Primary succession is the
series of changes that occur in
an area where no soil or organisms exist.

What Is Pollution?Water pollution is the addition of any substance that has a negative effect on water or the living things that depend on the water.

Water Pollution
Wastes produced by households, agriculture, industry, mining, and other human activities can end up in water.
