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…
