2
Ecological Successions

Series of predictable changes that occur over
time in response to disturbances.
Two types
Primary Occurs on new ground (little/no soil)
Glacier melt
Volcanic lava/ash
Secondary
Disturbance over existing soil (ex. old farmland)

3
Primary Succession

Occurs where no ecosystem was before.
On rocks, cliffs
Soil building occurs

4
Primary Succession

Soil particle sizes how they are classified

5
Primary Succession

Volcano addingnew land to Hawaii

6
Primary Succession

Lichens begin growing

Mosses on rocks

Primary succession can be seen happening on the
sidewalks.
If left alone, even NYC would return to a cement
filled woodland.

Primary Succession

Grasses and other species begin to cover in
subsequent years

Trophic Levels
Tertiary Consumers(Carnivores eat carnivores)
Top two also contain Omnivores (Eat plants and
animals)
Secondary Consumers (Carnivores eat herbivores)
Primary Consumers (Herbivores eat plants)
Producers (Plants)
Decomposers (bacteria and fungi)
23
Trophic Levels

How the numbers of these type organisms actually
compare to each other.

Food Webs
An example of a Food Web Shows how many
organisms are interconnected by different paths.
27
Food Chain
Food chains are different from food webs.
Chains only show ONE path of energy flow.
