1. What do you suppose the TFS football field looked like 100 years ago.

2. What do you suppose the TFS football field would look like 100 years from now if left untouched?

3. What do you think the word succession might mean?

Limiting Factors

• Any biotic or abiotic factor that restricts existence, numbers, reproduction or distribution of organisms. Common limiting factors:– Sunlight, climate, temperature, water, food, fire,

soil, space, other organisms

• Imagine if the entire school were locked in our classroom for an entire week. What would limit our survival?

Tolerance

The ability of an organism to withstand fluctuations in biotic

and abiotic environmental factors

(Ability to deal with change)

Succession

Succession

Orderly and predictable natural changes and species

replacements that take place in the communities of an

ecosystem

Sucession

Primary Succession

Takes place on land where there are no living organisms

(barren land)

Example: A forest growing in

an area where there is nothing

Pioneer Species

The first species to inhabit a new area

Ex) lichens and mosses

A lichen or moss will be the first species to enter an area

Climax Community

A stable, mature community that undergoes little or no change

in species

Secondary Succession

The Sequence of changes that takes place after an existing

community is severely disrupted in some way

Natural Disruptions: fire, tornado

Human Disruptions: deforestation

After this fire, a secondary succession will take place – the area will “start over”

What’s the difference?Question Primary Secondary

How much time does it take?

What does it start with?

Is the area old or new?

What type of pioneer species start the process?

What does it end with?

Sucession

Homework

C#3: Homework

Succession Drawing or flipbook or story

Think of an example of succession then draw or describe the sequence

of changes that took place
