Transcript Animal Adaptation examples

BELL WORK:
Copy the questions and write your answers.
Consider the different levels of organization in
an ecosystem (from Friday’s worksheet)…
1) How do population and community differ?
2) How do community and ecosystem differ?
CO: I will identify biomes and
compare adaptations in each.
LO: I will write notes and draw a
picture to represent each biome.
World Biomes
Important Vocabulary:
• Biotic factor: living organisms in a biome
• Abiotic factor: non-living things in a biome
• Adaptations: a characteristic that differs
among organisms that increases an
organism’s chance of survival
Biomes are a group of ecosystems with
similar climates (temperature and
rainfall) and organisms.
1) Tropical Rainforest
 Location:
- Found near equator
- Little variation in
temperatures
- No distinct seasons
Earth's most complex land
biome

Tropical Rainforest
• Abiotic factors
 high biodiversity
 both hot and moist
 ideal for decomposters
(bacteria, microorganisms)
 A lot of rainfall

 Plant Adaptation
examples
1. Most sunlight does not
reach floor
2. Plants grow in layers
(“canopy”)
3. Shallow, wide roots
 Animal Adaptation examples
1. Adapted to levels in canopy (claws, eye size, etc)
2. Camouflage

2) Temperate Deciduous Forests
• Location:
 Temperate zone
 Where most the human population lives
 Has 4 seasons
Temperate Deciduous Forests
 Abiotic Factors
 Deep, nutrient-rich soil
 Average precipitation in all forms
 Has abundant amount of deciduous (leaf bearing
trees)
 Plant adaptations
High diversity due to increased sunlight
Trees become dormant in winter
 Animal Adaptation examples
 Lose winter coat
 Adapt to many seasons
 Eat from different layers
of the forest
3) Taiga
aka Northern Coniferous Forest or Boreal Forest
 Location: Found only in Northern Hemisphere
• Abiotic factors
 Winters are long and
cold
 Precipitation is mostly
snow
 Soil poor in nutrients
 Short growing season
Taiga Plant adaptations




Fireweed
Coniferous (needle-bearing) trees
are abundant
Roots long to anchor trees
Needles long, thin and waxy
Low sunlight and poor soil keeps
plants from growing on forest floor

Balsam Fir
 Animal Adaptations examples
 Adapt for cold winters
 Burrow, hibernate
 Warm coat, insulation
4) Grasslands
• Location: Found in the right above and below
equator
• Contain the greatest number of grazing
animals on Earth.
• Abiotic Factors
 Rainy and dry season
 Amount of precipitation supports tall
grasses but only occasional trees.
 Fire plays a large role in this
ecosystem
 Plant Adaptation examples
 Grows in groups
 Resistance to drought
 Thorns and sharp leaves to protect against predation.
 Animal Adaptation examples
• Adapt for short rainy season—migrate as
necessary
• Reproduce during rainy season—ensures
more young survive
5) Desert
 Location: Various depending on type of desert
Mainly near equator
 Abiotic Factors:
Less than 10 inches of rain per year
Poor soil quality
• Plant Adaptation examples:
 Spines
 Thick, waxy cuticle
 Shallow, broad roots
Animal Adaptation examples:




Get water from food
Burrow during day
Large ears
Smaller animals = less surface area
6) Tundra
 Location: Found north of the Arctic Circle
 Abiotic Factors:
Cold temperatures
Low precipitation
Short growing season
 Plant Adaptation examples:
Grow close to the ground
Shallow roots to absorb the limited water resources.
 Animal Adaptation examples:
 Insulation (thick coat)
 Migrate often
 Few predators
7) Oceans

Location: Covers nearly ¾ of the Earth’s surface.

Abiotic Factors:

Most productive in shallow waters (where
sunlight is available)
 Plant adaptation examples:
- Plants are micro and macroscopic
- Have floating plants (kelp shown here)
- Developed relationship with marine animals

 Animal Adaptation examples:
 Phytoplankton: base of marine food chain
 Gills, fins
 Eye positions and shapes
