Biotic and Abiotic Factors
 Abiotic factors are essentially non-
living components that effect the
living organisms (ie: cloud cover,
seasons, location, altitude)
 Biotic factors are all the living things
or their materials that directly or
indirectly affect an organism in its
environment. This would include
organisms, their presence, parts,
interaction, and wastes

 A hot, humid biome near the
equator, with much rainfall and a
wide variety of life
 Vegetation: trees, vines, fungi,
broadleaf woody species-thin bark,
shallow roots, buttresses, vines
 Animals: More species of insects,
reptiles, and amphibians than any place
else, small mammals, birds
 Wet season, short dry season, hot
temperature

Temperate Rainforest
Temperate rainforests are coniferous or broadleaf forests
that occur in the temperate zone and receive high rainfall.
Temperate Rainforest
 Moisture: Abundant precipitation
200–400 cm, rain and snow.
 Temperature: Cool temperatures,
rarely below 5°F or above 100°F
 Vegetation:Diversity of conifers
and hardwoods, many tall and old.
 Animals: mammals(deer, bears),
slugs, birds

Midlatitude Grasslands
A biome where
grasses, not
trees, are the
main plant life.
Prairies are one
kind of
grassland
region.
Midlatitude Grassland
 Moisture: tall-grass, which are humid
and very wet, and short-grass, which
are dry
 Temperature:-40° F in winter, and in
the summer it can be as high 70° F
 Vegetation: large, rolling terrains of
grasses, flowers and herbs.
 Animals:large and small mammals,
birds, insects

Savanna
A savanna is a rolling grassland scattered with shrubs
and isolated trees,
which can be found between a tropical rainforest and
desert biome.

Biome “Report”
1-2 pages, Due Tuesday
1. Students are asked to build a three-dimensional model of
a biome in a box (no larger than a shoebox) using
everyday materials. Included in the model should be
representative examples of flora and fauna, and it should
show the terrain (mountainous, flat, shoreline, etc.). The
inside walls of the box should be decorated (painted,
collaged with photos, etc.) . Taped onto one side of the
box should be a written description of all of the
characteristics of the biome (elevation, precipitation levels,
temperature , flora, fauna, animals etc). Taped onto the
other side of the box is a world map indicating (by color,
outline, etc.) the locations of this biome.
