Biotic Factors: The living parts of an ecosystem.
Examples:
Animals
Fungus
Trees
Plants
Humans
Bacteria
Abiotic Factors: Non-living parts of an ecosystem.
Examples:
-Soil
-Rocks
-Minerals
-Water
-Air/Gases
-Weather/Climate
Biosphere:Area where there are living
things on earth
-From the bottom of the ocean to 10 miles of atmosphere.
Ecosystem: A habitat where a community of organisms—animals, people, and plants—interact with one another and with their physical environment.
It includes other components such as soils, water, and nutrients that support the organisms living in an ecosystem. Human well-being depends on the services provided by ecosystems and their components.
Using your homework from last night, explain how your biotic factors rely on each other and on the abiotic factors of your ecosystem to survive.
Read the front and back page on the board titled “The Biosphere.”Write the following sentences in your notes section and fi ll in the blanks with these words: population, biome, niche.
A __________ is specific to a creature. It usually explains how something behaves, lives, and protects itself.
A habitat is smaller than an ecosystem and is classified by the ___________ or community.
We live in an area with a temperate deciduous forest. This area named for its vegetation and climate is called a __________.
Read the front and back page on the board titled
“The Biosphere.”
Think about the differences between a
biome, ecosystem, habitat and niche.
Primary Producer
Any living plant-like organism that produces energy.
Produces it’s own energy through photosynthesis.
Examples: Tree, Flowers, Blueberries, Watermelon, Algae
Primary Consumer
An organism that directly eats primary producers. (Plants)-Plant-eating animals
Examples: Caribou, Elk, Deer, Flying Squirrels, Insects, Zebras
Secondary ConsumerEats primary consumers (Eats the plant-eater).
Examples: Owls, Weasels, Raccoons, Skunks
Tertiary Consumer
Can eat secondary and primary consumers
Examples: Lions, Tigers, Bears, Humans,
CarnivoreA living organism that only eats meat.
HerbivoreA living organism that eats only plants.
OmnivoreA living organism that eats both plants and animals.
Share 10 biotic factors with your group and their classifications. Be sure to circle any answers that you are unsure of.
Decomposers
A biotic factor that breaks down dead organisms.
Sentinel SpeciesAn animal that is sensitive to change in the environment, which allow us to see problems and changes in the environment.
Adaptation
A change in an organism that allows it to change to its environment or be more successful.
Structural Adaptation
When an animal has something specific about their body that helps them to survive.
A change in the organism’s body that happens over time. (Evolution)
Functional Adaptation
Allows the organism to adjust its body systems or functions to different
environments.
Structural Adaptations
Examples:
Polar Bear thick skin-keep warm
Giraffes have long necks-reach leaves
Deer and Elk flat teeth-grind food
Tiger and Lions sharp teeth-rip apart meat
Birds beaks to eat-different wings to fly/swim/soar
Camel has hump to store water and fat
Ducks have webbed feet-to swim
Functional Adaptations
Examples:
Mammals warm blooded-keep body temp
Cold-Blooded animals- hibernate, change body temp
Alligator/Turtle- lungs can fill to stay under water
