Transcript Biological Classification Levels Lesson PowerPoint

What Does an Organism Get
from Its Environment?
• An organism gets food, water, shelter, and other
things it needs to live, grow, and reproduce from
its environment.
• An environment that provides the things an
organism needs to live, grow, and reproduce is
called its habitat.
• Organisms with different needs live in different
habitats.
What Are Two Parts of an
Organism’s Habitat?
• Biotic factors are the living or once living parts
of a habitat.
• Abiotic factors are the nonliving parts of a
habitat.
– Sunlight
– Soil
– Temperature
– Oxygen
– Water
So how is a Biome different
from an Ecosystem or Habitat?
• Habitat: the area or environment where an
organism or ecological community normally lives
or occurs.
• An Ecosystem: a system formed by the
interaction of a community of organisms with
their physical environment. It includes many
habitats and living and non-living things.
• A Biome is a major regional grouping with
similar climate, plants, and animals.
Levels of Organization in an
Organism’s Environment
• From smallest to largest, the environmental levels
are:
– Organism or Individual: A single living thing
– Population: A group of organisms of the same
species living in a particular area
– Community: All the different species that live
together in an area
– Ecosystem: The community of species that live in
an area, along with the abiotic factors in the area
How Is an Ecosystem
Organized?
What in the world is a biome?!
•Scientists have developed the
term Biome to describe areas on
the earth with similar climate,
plants, and animals.
•Biomes are made up of
•several ecosystems
Levels of Organization in an
Organism’s Environment
How is a biome different than an
ecosystem or a habitat?
• Habitat: the area or environment where an
organism or ecological community normally
lives or occurs.
– Think of yourself as the organism. Your house
is your habitat, but your community (all the
people, and animals in your area) is Lost Creek
Ranch or the City of Allen (depending on how
much area you want to include). So that is like
one big habitat.
How is a biome different than an
ecosystem or a habitat?
• An Ecosystem: a system formed by the
interaction of a community of organisms with
their physical environment. It includes many
habitats and living and non-living things.
– Your ecosystem would be more like the state of
Texas or the southwest United States and it
would include the land and water here not just
the people and animals.
How is a biome different than an
ecosystem or a habitat?
• A Biome is a major regional grouping with
similar climate, plants, and animals.
– Your biome would be the United States.
– There are many different types of Biomes!
• Let’s look back at our classification pyramid
in a different way now.

Biomes of the World
A journey across the Earth
in 30 minutes…
What biomes are on Earth?
• Scientists can’t agree on exactly how many biomes
Earth has!! One scientist pictures the biomes like
this:
The North Western Hemisphere
• Let’s take a closer look at where we live…
Another way to look at it…
Let’s take a closer look
at some specific biomes…
Aquatic Biomes:
• Water: Submerged
• Temperature: Varies
• Soil: None
• Plants: Aquatic Plants (seaweed)
• Animals: Fish, Shelled fish, invertebrates
(animals with out backbones), select
mammals.
Aquatic Biome
Tropical Rainforest
• Water: Very wet
• Temperature: Very warm
• Soil: Poor, thin soil
• Plants: Many plants (trees, flowers, shrubs,
etc.)
• Animals: Many animals (birds, mammals,
reptiles, insects, etc.) Many endangered
species with a lot of competition for resources.
• Near the Equator
Rainforests
Tundra
• Water: Dry
• Temperature: Cold
• Soil: Permafrost (frozen soil)
• Plants: Lichens and mosses
• Animals: Migrating animals, and small
rodents
• Located near the North Pole.
Tundra
Taiga
(also know as the Boreal Forest)
• Water: Adequate
• Temperature: Cool (year round)
• Soil: Poor, rocky soil
• Plants: Conifers (pine trees – evergreen trees)
• Animals: Many mammals, birds, insects,
arachnids, etc.
• Far Northern regions just south of the Tundra
Taiga
Grassland
• Water: Wet season, dry season
• Temperature: Warm to hot (but often has a
cold season)
• Soil: Fertile soil
• Plants: Grasses (few or no trees)
• Animals: Many mammals, birds, insects,
arachnids, etc.
• Located in Temperate Climate Zones
Grassland
Temperate Forest
(Deciduous Forest)
• Water: Adequate
• Temperature: Cool season and warm
season
• Soil: Fertile soil
• Plants: Deciduous trees (trees that loose
their leaves), shrubs, ground cover
• Animals: Many mammals, birds, reptiles,
insects, arachnids, etc.
Temperate Forest
Desert
• Water: Dry (almost none)
• Temperature: Hot or Cold (one or the
other)
• Soil: Poor (sandy)
• Plants: Sparse - succulents (like cactus),
sage brush
• Animals: Sparse - insects, arachnids,
reptiles and birds (often nocturnal)
Desert
Summary
• What is a biome?
• Name some of the world’s biomes…
• What might location in the world
(latitude and longitude) have to do with
a biome?
