Title: Ch 3.1 and 4.1 Ecology
L.O. SWBAT compare and describe abiotic and biotic factors in
a biome.
3.1 What is ecology?
The study of interactions among organisms
They study the biosphere – from Earth’s atmosphere to the trenches of the ocean and everything in-between
What is ecology?
These interactions are interdependent: everything is connected
We are constantly changing our surroundings by our habits (eating, driving, creating houses, etc).
Levels of Organization
Organism
Population
Community
Ecosystem
Biome
Planet Earth
Species: group of similar organisms that can breed and reproduce
Group of species
Different populations together
All organisms in an area & their non-living parts
Group of ecosystems that share similar climates and organisms
Levels of Organization
Amoeba Sisters Ecological Succession
Review: Biotic vs. Abiotic
Biotic: Living-Ex: Animals, plants, bacteria
Abiotic: Non-living-Ex: Sunlight, water, heat, soil
What levels of organization include abiotic factors?
Energy, Producers & Consumers
We need energy in order to survive… to get out of bed in the morning!
You can get your energy from a poptart, but where did the poptart get it?
Energy, Producers & Consumers
The ultimate source of energy is the sun!
Photosynthesis:Plants converting energy from the sun into “food”
Sometimes, organisms get energy from chemicals: Chemosynthesis
Bacteria that use sulfur deep in the ocean, or in volcanoes.
Energy, Producers & Consumers
Autotrophs:
• Primary Producers
• use solar / chemical energy to produce “food”.
• “food” - organic (contains Carbon)
Energy is stored and passed on to others. Without autotrophs, our ecosystem wouldn’t have any energy and you wouldn’t have any food!
Reminder!
Law of Conservation of Energy
Energy cannot be created nor destroyed, it can only be transferred and converted!!
Energy, Producers & Consumers
We cannot make our own energy, we have to get it from other organisms
-Known as Heterotrophs or Consumers
Energy, Producers, and Consumers
Different kinds of Consumers: Carnivores: kill and eat other animals
(komodo dragon)Scavengers: eat bodies of dead animals
(hyenas)Decomposers: break down organic matter
(bacteria)Herbivores: eat plant parts
(birds)Omnivores: eat both plants and animals
(humans)Detritivores: eat decomposers
(cockroaches)

Did you finish the summary as part of your homework?
Re-read your summary and ask yourself
Is my summary a good reflection of what I learned?
Did I use the words although, because, but, so to expand my reasoning?
I Forgot about the summary!
It is part of your grade! Get it done now…
