3 types of biodiversity
- species diversity
- genetic
- ecological
refers to variety of different types of species found in particular area
species diversity
refers to varieations among genetic resources of organisms
genetic diversity
refers to variety of different types of species found in particular area
ecological diversity
rainforests that occur in areas of tropical rainforest climate in which there isno dry season– all months have an average precipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rainforest
tropical rainforest
forest found between the tropical and boreal/taiga regions, located in the temperate zone. It is the second largest biome on the planet, covering 25% of the world’s forest area, only behind the boreal forest, which covers about 33%.
temperate forest
meaning Northern forest because it is located in the northern hemisphere that covers 17% of the earths land.
Coniferous/Taiga/Boreal/Snow forest
arefound to the north and south of tropical rainforest biomes(natural community). Plants and animals have to adapt to the long dry periods.
tropical graslland/savannah
areareas of open grassy plains that are sparsely populated with trees seen in Argentina, Australia and North America.
temperate grasslands

ecosystem
contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms
ecosystem
a place in which a
particular species of organism lives.
