OBJ: Intro to Ecology

Variety of Life on Earth

Biodiversity

Categories of Organisms in an Ecosystem

ProducersOrganism which makes its own food (plants)

ConsumersOrganism which must eat another organism

HerbivoreConsumer which eats plants (producers)

CarnivoreConsumer which eats other animals

OmnivoreConsumer which eats plants and animals.

DecomposerConsumer which breaks down the remains of another dead organism into unrecognizable materials.

PredatorCarnivore which hunts other organisms for food

ScavengerCarnivore which finds and eats already dead organisms

Energy Transfer in an Ecosystem

BiomassOrganic material manufactured by producers.

Trophic LevelFeeding level in an

ecosystem.

Biological Species Concept: A species is a group of organisms that can breed and produce fertile offspring.

CHAPTER 15 NOTES

SpeciationThe creation of a new species is

considered SPECIATION.

Barriers to producing offspring - Reproductive Isolation –

◦Timing – Different Breeding Seasons Ex. Jan. or Feb

◦Behavior – Different Mating Rituals ex. Mating calls

◦Habitat – Different habitats in the same geographical location

Geographic IsolationPlants vs. Animals

◦stationary vs. mobile

Barriers to producing offspring -

The more barriers-more speciation

Speciation: the gradual change into two separate species

More barriers less likely to exchange genetic material

Less sharing of material-more differences occur

The more differences the more likely we will create two new species

QU: Describe a species.

HW: Due on Monday!!

OBJ: Over Ch 14 Test, Taxonomy

Where are you

from?

Answers usually vary depending where you are at that point.

◦Michigan?◦Another state?◦Another country?◦Another planet?

Where are you from?

Can be confusing…..

Saying where you are from can be confusing…

Imagine trying to name every individual species…◦Special way to classify all organsims!!

Called TAXONOMY…what you will be reading about today

QU: Why do common names present problems to scientists?

Chapter 15 and 36 Test on THURSDAY!!

OBJ: Taxonomy and the 3 Domains

Dichotomous Key

A dichotomous key is a tool that allows the user to determine the identity of items in the natural world.

Keys consist of a series of choices that lead the user to the correct name of a given item.

Dichotomous Key

Dichotomous Key

Phylogenetic Tree

A tree that shows evolutionary relationships between different species.

Phylogenetic Relationship…

QU: Describe how a phylogenetic tree differs from a dichotomous key.

**Ch 15 and 36 Quest Thursday***Ch Review Due Thursday*

OBJ: Domain Notes and Over Homework

Differences in domains….

Three Domain System Archaea Domain

◦Archaebacteria Kingdom

Bacteria Domain◦Eubacteria Kingdom

Eukarya Domain◦Protista Kingdom◦Fungi Kingdom◦Plantae Kingdom◦Animalia Kingdom

THE Domains

Archaea Domain◦microscopic organisms ◦single-celled prokaryotes.◦exist under some of the most extreme conditions

Bacteria Domain◦Prokaryotic organisms

THE Domains

Eukarya Domain◦Eukaryotic cells ◦Unicellular (protists) or Multicellular (most Fungi, Plantae, and Animalia)

THE Domains

Eukarya Kingdoms…

Protista: Usually unicellular, highly specialized

Fungi: Multicellular, cell wall, lack of mobility.

Plantae: Multicellular, cell wall, larger, autotroph

Animalia: Multicelluar, no cell wall, mobile

Punctuated EquilibriumDarwin – Evolution occurs gradually

◦Called Gradualism

◦BUT: Fossil evidence is missing transitions

SO………………….Punctuated Equilibrium – Evolution can be rapid.

◦Evolution is in spurts.◦Rapid is still 10,000’s of years.
